Abstract


Effect of charge carrier mobility on P3HT: PCBM based organic solar cell has been investigated in this study.  Numerical simulation for the structure ITO/PEDOT: PSS/P3HT: PCBM/Al has been done using simulating software GPVDM (General Purpose Photovoltaic Device Model). Hole mobility has been varied from 5*10-8 m2V-1S-1 to 100*10-8 m2V-1S-1at fixed electron mobility 2*10-8 m2V-1S-1and vice-versa. Short circuit current density, open circuit voltage, fill factor, efficiency has been studied to understand the dependency of carrier mobility on device performance. Result shows that efficiency is greatly influenced by charge carrier mobility.
