Optimum Morphology and Performance Gains of Organic Solar Cells
09 Sep 2011 | | Contributor(s):: Biswajit ray, Muhammad Alam
Morphology of light absorbing layer is known to dictate the power conversion efficiency of organic photovoltaic (OPV) cell. The innovation of bulk heterojunction (BHJ) led to significant improvement for exciton harvesting, but carrier recombination at the distributed interfaces and variability of...
