Sharp has developed solar cells that match the concentrator solar cell efficiency world record set by Solar Junction last year. The technology’s staggering 43.5% efficiency from a triple-junction compound solar cell is 1.2% higher than the efficiency of the cells holding the record before March of 2011 (when Solar Junction busted that record). The conversion efficiency was actually confirmed by the Fraunhofer Institute for Solar Energy in April 2012 (for some reason, these companies and researchers don’t let us know about the new records for months sometimes). “Compound solar cells utilize photo-absorption layers made from compounds consisting of two or more elements, such as indium and gallium,” Sharp writes. “The basic structure of this latest triple-junction compound solar cell uses Sharp’s proprietary technology that enables efficient stacking of the three photo-absorption layers, with InGaAs (indium gallium arsenide) as the bottom layer.”

Germany’s Renewable Energy Industry (IWR) announced that over the weekend the country’s solar energy infrastructure met approximately 50% of the country’s energy demand. The IWR notes that more than 22 gigawatts of solar energy per hour was generated by the country’s various alternative energy systems and fed into the energy grid. This is comparable to the energy generated by 20 nuclear power plants operating at full capacity. This marks a new record for Germany and sets the bar higher for the global solar energy industry Government officials claim that this milestone is proof of the viability of solar energy. The fact that the country was able to meet half of its energy needs through the use of solar power during the weekend is being considered a major accomplishment. The German solar energy industry continues to break records and show that alternative energy should be taken more seriously by developed countries.
