New Solar Cell Efficiency Record for Organic Solar Cells

New Solar Cell Efficiency Record for Organic Solar Cells

The most organic solar cell possible is a leaf, but photosynthesis is ridiculously difficult to reproduce . That hasn’t stopped a number of researchers from trying, and this week an American company from Illinois has set the new efficiency record for an organic solar cell, or OPV. So Close to the Magic Number Polyera, based in Skokie, Illinois (a suburb of Chicago), announced 9.1% efficiency in the lab, and the results were confirmed by Newport Corporation of Irvine, California. Given some of the previous efficiency levels reported for solar cells (current records are around 17% for some types of relatively cheap solar cells , somewhere in the 25% range for others, over 30% for high concentrating photovoltaic (HCPV) modules , and over 43% for concentrated photovoltaic cells ), this may not seem like much. However, commercial viability is based on a mixture of cost and effi...
