Solar's Outlook Dazzles

At the end of last year, the global photovoltaic market hit a cumulative installed capacity of 40 GW, of which 16.6 GW was added during 2010. A year of unprecedented growth saw new capacity more than double from 7.2 GW in 2009. Worldwide, solar PV already produces some 50 TWh each year. By 2015, though, capacity could climb to range from 131 GW to 196 GW. (...) Germany continued to lead the PV market worldwide, with 7.4 GW installed over the year, while Italy added a substantial 2.3 GW. Other countries with significant growth included the Czech Republic, which saw a 1.5 GW expansion in 2010, a rise unlikely to be sustained in 2011. Japan gained 990 MW, the United States 900 MW, and France 700 MW. Spain regained some ground by installing 370 MW after two years of strongly adverse conditions. Belgium connected more than 420 MW of PV.

Record Efficiency of 18.7% for Flexible CIGS Solar Cells

Renewable Energy News
Scientists at Empa, the Swiss Federal Laboratories for Materials Science and Technology, have further boosted the energy conversion efficiency of flexible solar cells made of copper indium gallium (di)selenide (also known as CIGS) to a new world record of 18.7% – a significant improvement over the previous record of 17.6% achieved by the same team in June 2010.

China doubles solar power target by 2020

AFP report
China has more than doubled its target for solar power capacity to 50 gigawatts by 2020, state media said, as the world's largest polluter steps up efforts to boost clean energy sources. The increased target follows a massive earthquake and tsunami in Japan that triggered a nuclear crisis in the country's northeast and fuelled worldwide debate about the safety of atomic power. China hopes its installed solar power capacity will reach 10 gigawatts by 2015 and 50 gigawatts by the end of the decade, the Shanghai Securities News said, citing Li Junfeng, deputy director of the energy research arm of the National Development and Reform Commission. The country's current installed capacity is less than one gigawatt, the official China Daily said last month. Li said China will soon publish a five-year blueprint and other supportive policies for the solar power industry. (...) It currently relies on carbon-belching coal for 70 percent of its energy needs.
