Optimum Morphology and Performance Gains of Organic Solar Cells

09 Sep 2011 | Online Presentations | 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...

Modeling and Optimization of Polymer Based Bulk Heterojunction (BH) Solar Cell

15 Feb 2010 | Online Presentations | Contributor(s): Biswajit ray

A polymer phase separation model based on Cahn-Hilliard equation and a three-dimensional (3D) coupled exciton/electron/hole transport model in the disordered, phase-segregated morphology so generated, allow us to predict, possibly for the first time, the morphology dependent performance limits...
