Click to enlarge.Mitsubishi Cooperation (MC), the National Institute of Advanced Industrial Science and Technology (AIST) and Tokki Corporation have developed a new, highly-integrated Organic Photovoltaics (OPV) module. Like silicone PVs, OPVs employ a P-N diode junction as a generating active layer. The biggest challenge over some 30 plus years of R&D has been raising the low power output of PVs. In January, 2005, AIST achieved 4.0% light exchange efficiency with the introduction of a bulk-hetero junction (i-layer). At the time, this was...
