High performance and efficiency enhancement for organic solar cell : layers thickness optimization

Abstract

Abstract A mathematical modeling for performance and efficiency for organic solar cell is presented, bulk hetero-junction photovoltaic of ITO layer (indium tin oxide), P3HT (Poly3-Hexylphiophene) PCBM (phenyl C61-butyric acid methyl ester) was investigated, the results show main effect of all layers thickness and a major effect for the active layer thickness of the electrical energy obtained for this OPV solar cell due to open circuit voltage, fill factor and short circuit current for the OPV solar cell. The efficiency investigation was done according to J-V curves obtained from GVPDM (General photovoltaic purpose device model) which built according to optical treatment and drift diffusion model based on the poisson’s equation solution, we started from 1e-5 to 1e-9 meter thickness for each layer, then by taking optimum thickness for each layer which are about 1e-7 meter we investigate the efficiency for active layer thickness between (1e-7 to 9e-7), the efficiency obtained was about 3.7 to 2.7 respectively.
