New findings to help extend high efficiency solar cells' lifetime

Monday, April 7, 2014 - 07:30 in Physics & Chemistry

OIST's Energy Materials and Surface Sciences Unit has made a surprising discovery about the degradation of solar cells that could help pave the way to creating a longer lifetime for these cells.  Key factors for creating cost-efficient solar cells to compete with conventional energy sources like fossil fuels include fabrication cost, efficiency and lifetime of the cells.  Professor Yabing Qi and members of his team have investigated the cause of degradation of a high efficiency solar cell.  This discovery, published in The Journal of Physical Chemistry Letters, can help move various forms of solar cell technology forward now that researchers know what is causing degradation and shortening the lifespan.
