Determining shunt resistances <i>via</i> modeling the photovoltaic performance of organic solar cells
Dashan Qin, Mengyu Qiu, Xiaowei Zhan
Abstract
The thermal vibration of molecules is markedly enhanced upon illumination (photoexcitation), leading to an increase in the (vibrational) free volume of photoactive layer and thereby markedly decreasing shunt resistance of device.
