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%


Experimental Smart House Completed In Tokyo University

August 19th, 2011 | by Charis Michelsen

The Institute of Industrial Science of Tokyo University, widely regarded as the top university in Japan, has erected a "smart house" on their Komaba Campus, in cooperation with LIXIL Housing Corporation's Eyeful Home Company. The current structure, the COMMA house (COMfort MAnagement), is the start of a series of prototypes and tests geared toward creating more-or-less self-sufficient home. The project is expected to have plans for a standard smart house by
