Making Cheaper and More Efficient Solar Cells with Copper

September 8th, 2011 | by Charis Michelsen

There are two ways to lower the cost of producing energy through photovoltaics – more efficient solar cells (more power per square foot) and lower production costs (lower cost per square foot). The ETAlab of the Fraunhofer ISE has devised a way to do both simultaneously. The research team in the laboratory for new solar cell structures and processing steps has not only made the solar cell contacts out of 100% cost-effective materials (replacing expensive silver with cheaper copper and nickel), but the process also increases the efficiency of the solar cell to a very respectable 21.4%


Panasonic’s Solar Cells Take On the World Solar Challenge

August 26th, 2011 | by Charis Michelsen

Specialized challenges are usually pretty entertaining – wacky ideas come to life to compete, and often garner some pretty impressive results. The upcoming World Solar Challenge in Australia should deliver some fun; competitors must drive from Darwin to Adelaide, a total of 1,864 miles across the desert, without using any fossil fuel


Screen-Printed Solar Cell Sets New Efficiency Record – 20.2%

August 25th, 2011 | by Charis Michelsen

SCHOTT Solar announced the world’s first monocrystalline screen-printed solar cell on Wednesday -- with conversion efficiency of 20.2%. The Fraunhofer ISE in Freiburg, another research institute, confirmed the results of SCHOTT Solar’s tests with an independent measurement
