MST's a new breakthrough in solar energy

MST is located in Israel, the PV system developers, the company developed the first solar photovoltaic concentrator network system of Israel and became Israeli photovoltaic electricity subsidy policy Xiadi a feed-in tariff to enjoy the company.

MST's concentrating solar network time July 12, 2010, the system is that Israel and the world's first type of optical network systems.

The system capacity 50KWp, and has been Israel's electricity sector, access permission, and to receive more than 20 years the Israeli government subsidies for photovoltaic FIT through the sale of electricity MST's of the project is likely to achieve the desired profit.

MST is the Israeli system uses technology developed by the MST construction companies. The company's management and operators is Mr. Dov Raviv - Israeli father of the famous rocket missiles. MST system works in a multi-junction solar cell based on the intensity of radiation 500 times the light gathering, resulting in a smaller space to gather more energy. This advanced solar cell had previously been used in space satellites, but the ground has begun to be used in photovoltaic systems.

This highly efficient solar cells for solar tracking devices coupled with further significant increase in efficiency, solar tracker can accurately track the sunrise and sunset and thus make the system to maximize exposure to the sun radiation produce as much electricity. The dual-axis solar tracking system is the invention of the MST's developed the system technology used in the current situation is also the world's most advanced.

The system has been almost a year of field testing, test data show that the system capacity has reached 24.5% capacity efficiency. The data is almost standard now twice the efficiency of crystalline silicon systems.

MST is the biggest advantage of the system in less space can produce more energy, the same energy output conditions, MST system, the space occupied by the other half of photovoltaic systems technology or even a third. Efficient use of space in the name "dual use" of the MST system has become more evident. The system was installed in a two-meter-high metal frame, so the system or the surrounding land can still be used for agricultural or other purposes. The system is currently being installed in the southern city of Arad in Israel.

CPV distance the core business promising

CPV distance the core business promising

Concentrator photovoltaic (CPV) is after the convergence of high conversion efficiency of sunlight through photovoltaic cells directly into electrical energy technologies, CPV is concentrating solar power technology is the most typical representatives.

Using crystalline silicon cells and thin-film battery photoelectric conversion, respectively, first and second generation solar technology, have been widely used. The use of optical components that convert sunlight to generate electricity together and then make use of concentrating solar technology, solar power is considered the future trend of third-generation technology.

Advantages and shortcomings

Our prospects for the development of CPV cautious optimism, based primarily on the following three reasons:

First, the high potential for scale: CPV technology because of its photoelectric conversion efficiency and high, in the foreseeable future time can be used to support the construction of large-scale solar power generation technology the best.

Second, the cost reduction is big: the crystalline silicon and thin film solar technology compared, CPV currently 3 to 4 $ / Wp of the construction costs have an advantage, but as an emerging technology, with the expansion of production scale, the battery efficiency improvement, improvement of concentrator modules, the cost of a huge decline in space.

Third, technical progress and scale of uncertainty: as a being from the laboratory to the engineering of new technologies, CPV technology line has not been established, nor the formation of the industrial chain. For related businesses, we need to focus on technical or cost advantage of its position.

Important future clean power

With crystalline silicon and thin-film solar power system compared to the flat, CPV because of its high conversion efficiency and a much smaller amount of semiconductor material, is the most potential to develop into large-scale solar power to support power generation. By simple replication of large-scale deployment, a single CPV power plant can easily reach MW class size, and even the future of this figure is expected to reach 100MW.

Small footprint: in the case of equivalent capacity, CPV power plant occupies an area of land is much smaller than the flat-plate solar. CPV system consists of pillar bearing the main structure, small footprint, and because the system generates the shaded area on the ground is moving, so the power plant site ecological impacts would be smaller, the bottom panel of the land can still be used for livestock, etc. purposes.

Water consumption is very low: usually in areas with high solar radiation are relatively dry, CPV systems throughout the power generation process completely without water, only a small amount of water used to clean the glass to photovoltaic modules. And concentrating solar thermal (CST), nuclear power, IGCC and other clean power generation technology compared to, CPV has a significant water-saving advantages.

According to the current understanding, CPV's technical characteristics required to install the solar radiation intensity throughout the year to 1800kWh / m & sup over the world to meet the conditions of the region include: the southwestern United States, southern Europe, northern Africa, southern, Middle East and Australia , there are some areas in northwest China's construction of CPV systems with better natural conditions.

In the current production of CPV systems is still very limited circumstances, many systems and components manufacturers in the production process still using a lot of manual operations, especially in component assembly and other aspects, the amount of the future, once up, large-scale automated production will is inevitable.

However, the budding CPV systems engineering special time, domestic enterprises might play a "Made in China" opportunity cost advantages, some of the relevant technical capacity of domestic enterprises to take this opportunity if the emerging markets in the first set the advantage, future growth is huge.

Development of new energy enterprises in Shenzhen to make Taiwan counterparts "shines", while government departments on the new energy industry support policies, but also to Taiwan expert was surprised and excited. 8, participate in the sixth cross-strait trade and cultural forum of experts, the first visit in Shenzhen, the new energy and cultural and educational development. Reporters accompanying the visiting group of new energy-site interviews.

"Shenzhen counterparts done a good job"

Morning, the new energy industry leaders and experts first came to Shenzhen to visit Trony Technology Development Co., Ltd..

The company's chairman and president Li introduction, founded in 1993, the benefits from the company, is currently the largest amorphous silicon thin film solar cell manufacturers and solution providers, is the only company with more than 100 photovoltaic produce its own brand of patented technology solar energy company, master of the second generation thin film solar cell production and development of core technology.

After the meeting, Chairman of Taiwan's Central Group Director Liu Qi told reporters, we are businessmen counterparts, we are concerned with scientific and technological achievements is the distance between the market, the cost can be reduced to simple terms is how much the market will be able to do much; At the same time want to learn new mainland energy companies to understand the extent of the international market. "Shenzhen's peers doing well."

In fact, the benefits from science and technology in 2006 to complete the "low-cost photovoltaic glass curtain wall" of research projects and the acceptance by the national expert group; 2009, the "low-cost amorphous silicon BIPV curtain wall components" technology, won the annual global investment in renewable energy value of the top ten most leading-edge technology, "Blue Sky Award."

If the two sides together to the global market share of photovoltaic power generation for more than 70%

Subsequently, the group went to visit is located in Bao'an District, Shenzhen City, Taima scenery Energy Technology Co., Ltd.. The company was founded in 2008 as a technology innovation enterprises, Taima is a magnetic levitation wind turbine technology systems development, manufacturing, sales, engineering and integration services for high-tech enterprise, has been involved in a number of national, provincial, municipal energy conservation technology research projects, products in China, USA, China Taiwan, Singapore, Australia, New Zealand and other countries and regions have begun to practical application.

Taima, Chairman and magnetic levitation wind power generator systems, the inventor Lin Wenqi led the team, after seven years of research, experienced many failures, and finally developed the world's first maglev wind turbines, small wind power to achieve a technical milestone leap. Taima technology has a number of independent intellectual property rights and patents, and have completed a number of international testing and certification.

Ke Dong, chairman of Taiwan believe Nagasaki, said the technology should be leading, but his appearance on the sample is not very appreciated. At the same time, he believes cost is the key, the current large-scale industry may have to overcome many problems.

Taiwan solar dry cloth Lin Jiang, general manager of financial calculations to reporters. He said that last year, the world's photovoltaic power generation capacity of 7 GW, the mainland accounted for 38%, Germany in second and Japan third, Taiwan 12%, ranked fourth, if the mainland and Taiwan, adding generating capacity , just 50%, but "if the two sides coming together to further each other's needs, then the performance will double share of global market share will soon be exceeded more than 70%." Choi said Lin Jiang.

BYD electric cars to enjoy government subsidies should learn from Taiwan

That reporters from the Shenzhen media, Tainan University of Technology Professor, Department of green energy Huang Zhenjiang immediately turn to the BYD electric cars up. "Shenzhen BYD battery-powered cars I already know, has been concerned." That the reporter was surprised, even the just-released government subsidies for new energy vehicles to a maximum subsidy of $ 120,000 so the latest news, he knows quite well chest. Professor Huang said that, in fact, started 10 years ago, Taiwan has experimented with electric drive vehicles, for various reasons, but no new progress in recent years. "Mainland policy to encourage new energy vehicles, would be appropriate to develop Taiwan's industrial policy from the boosting effect."

Huang Zhenjiang told reporters that Taiwan has abundant wind, the light of resources, to explore the beautiful area than the earlier generation, some aspects of walking in front of the mainland, such as small scenery generator technology is quite mature, however, inadequate investment in research and development of large generators engaged in the business is very small. Now, new energy, including Shenzhen, mainland enterprises have come from behind the trend, in turn, can promote the progress of Taiwan.

Huang Zhenjiang, "said first second-generation solar cells, the Western countries ahead of us, want to start from the third generation of solar cells in Taiwan and the mainland can progress together, with our original technology output, rather than in the global technology map OEM were to become - to sell when we are not a battery, but the entire production line!

Lithium-ion battery repair instrument design

The birth of mobile phone battery repair instrument background:

Development needs of contemporary society, almost everyone in the use of mobile phones, mobile phones have become one of daily necessities that we can not do without. The people in frequent use, and gradually find the phone battery does not meet our requirements, often appear after a period of time does not go electric charge, discharge time shorter case. A freshly charged battery is good, not long before no electricity, so a repair instrument repair mobile phone battery was born.

Design Principles

(A) the introduction of mobile phone batteries

Cell phone batteries are now generally used for lithium-ion battery. Mainly due to the lithium-ion battery is a lithium-ion (Li-Ion) and Lithium Polymer (Li-Pol), battery with a light weight, large capacity, internal resistance characteristics. But we need to follow its characteristics to be charged, otherwise it will be great damage, its number of charge cycles will be greatly discounted.

Lithium ions in the charging process does not need to pay attention to overcharge and over discharge, it has its own minimum voltage and maximum voltage, the general minimum voltage between 2.2V to 2.3V, the maximum voltage between 4.2V to 4.3V, so we be aware of when designing the circuit to set the discharge termination voltage and charge termination voltage.

(B) the design ideas

The design discharge and recharge circuit is divided into two phases. General battery charger only a simple charge, and the instrument repair more than a discharge.

Discharge the battery in the first stage of mainly the remnants of completely let go of power and value of its voltage reaches the discharge end. Discharge voltage discharge stage the main attention to the termination value of the set, if the battery had discharged, the battery will cause great damage.

We generally charge the charger stage, there are different, using the periodic changes in pulse frequency signal to charge the battery. Taking into account the main pulse can be battery chemicals gradually activated, the battery to the factory results. Similarly, in the charging voltage can not exceed the charge termination value, over charging the battery may also cause permanent damage.

Production process

(A) the discharge circuit design

1, the design requirements

a generally preferable to battery discharge current of 0.2 times the rated capacity.

b must accurately grasp the discharge voltage, so as to avoid over-discharge and damage the battery.

c manually on the discharge to start and stop control.

2, the design points

a battery discharge to the termination voltage, the discharge circuit should be disconnected automatically, or automatically transferred to the state of charge.

b easy status monitoring of discharge work.

The following design ideas for the discharge circuit diagram:

Discharge circuit

Part of two relay drive circuit constituted by a self-locking circuit, the discharge end of the switch is automatically disconnected, transferred to the charging section.

(B) the charging circuit design

1, the design specifications

a adjustable constant current charging, the maximum charge current 500mA.

b discharge end automatically transferred to constant current charging status.

c charge to the charge termination voltage, constant current circuit to stop working and lock "the end of charge" state.
