>20% efficiency modules
SunPower press release
Sunpower launched the SunPower™ E20 series of solar panels, the industry's first commercially-available solar panels to achieve total area efficiencies of 20 percent or more. The new 96-cell E20 solar panels are available in 333-watt and 327-watt models for rooftop installations and featureSunPower's 22.4 percent efficient patented Maxeon™ cell technology. The all-back contact Maxeon solar cell captures significantly more sunlight and conducts more electrical current than conventional solar cells, and holds the world record for efficiency among commercially available, mass-produced solar cells.

Germany Scraps Solar Energy Subsidy Cut as Merkel Exits Nuclear
Bloomberg
Germany scrapped a planned cut in subsidies paid to solar panel owners as Europe’s biggest electricity market seeks to exit nuclear power, according to a draft law published on the Environment Ministry’s website.
“There are no significant changes for electricity from photovoltaic facilities from those made in 2010,” reads the document, which details scheduled cuts in above-market rates paid to solar panel owners. Environment Minister Norbert Roettgen has said he considered an additional reduction in March next year. (...) The minister told reporters on May 30 that he considered a 6 percent aid cut in March 2012 that would come on top of reductions of as much as 24 percent between July and next January to adapt the subsidy to falling panel prices. (...) Germany, which uses nuclear for 23 percent of its power, plans to switch to renewable energy output after Japan’s reactor disaster stoked safety concerns. The government is balancing aid for energy from solar panels and wind turbines with the associated cost for citizens and industrial users, who finance the technology’s roll-out through their power bills.

Solar's Outlook Dazzles
RenewableEnergyWorld.com
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.
