もう日本は追い付けないかもしれません。通常の太陽電池では。
起死回生の量子ドットしかないでしょうか。。。
ファーストソーラー：中国と世界最大規模のソーラーパーク建設
ファーストソーラーと中国が、ソーラーパーク建設の協力取決め（ＭＯＵ）を結んだ。手始めに、内モンゴルの砂漠地帯に合計2,000MWe（世界最大規模）の発電所を作り、２０１９年には11,950MWeに拡大する計画。完成すれば、300万世帯の中国人に電気を供給できる壮大な計画。

U.S. Company and China Plan Solar Project
September 8, 2009
Chinese government officials signed an agreement on Tuesday with First Solar for a 2,000-megawatt photovoltaic farm to be built in the Mongolian desert.
Set for completion in 2019, the First Solar project represents the world’s biggest photovoltaic power plant project to date, and is part of an 11,950-megawatt renewable-energy park planned for Ordos City in Inner Mongolia.
The memorandum of understanding between Chinese officials and First Solar, the world’s largest photovoltaic cell manufacturer, would open a potentially vast solar market in China and follows the Chinese government’s recent moves to accelerate development of renewable energy.
When completed, the Ordos solar farm would generate enough electricity to power about three million Chinese homes, according to First Solar.
Most proposed large-scale solar projects use solar thermal technology. But as photovoltaic technology becomes more cost-competitive, utilities are turning to companies like First Solar for big solar power
farms.
Financial terms of the agreement have yet to be reached and will depend on China completing a feed-in tariff that pays a premium for electricity generated by renewable energy projects. First Solar said the 2,000-megawatt power plant would cost $5 billion to $6 billion if built in the United States today, but it said the cost to build such a project in China would probably be lower.
The company also has agreed to supply two California utilities with 1,100 megawatts of electricity
from three big solar farms.
Until the announcement of the Ordos project, the largest single photovoltaic power plant was the 550-megawatt Topaz solar farm to be built by First Solar in California. As solar panel prices continue to fall and projects like Ordos bring further economies of scale, photovoltaic farms are expected to become more competitive with solar thermal power plants.
Plans for the Ordos renewable energy park call for wind farms
to generate 6,950 megawatts, photovoltaic power plants to provide 3,900 megawatts and solar thermal farms to supply 720 megawatts. Biomass operations will contribute 310 megawatts; 70 megawatts will be available from hydro storage, a load-balancing technology that uses off-peak power to pump water to a high reservoir from which it can be released to turn turbines at peak demand periods.
