simulation of the performance parameters and carrier concentration profile of poly 3-hexyl thiophene / phenyl-c61-butyric acid methyl ester planar hetero-junction photovoltaic cell

In this research work, the performance parameters , such as fill factor (ff), external quantum efficiency (eqe) , maximum power density and carrier concentration profile of a planar hetero-junction poly 3-hexyl thiophene (p3ht) / phenyl-c61-butyric acid methyl ester (pcbm) photovoltaic cell has been simulated for different values of carrier mobility where the simulation has been performed under the consideration of incident solar radiation of 1 kw/m^2 irradiance, air mass of 1.5, ambient temperature of 300k and indium tin oxide (ito) and aluminium (al) has been considered as the anode and cathode of the p3ht/pcbm solar cell respectively. the performance parameters has been determined for electron mobility of 5 × 10^-4 , 5 × 10^-3 , 5 × 10^-2 and 5 × 10^-1 (cm2/v.s) at the acceptor and hole mobility of 1 × 10-4 , 1 × 10-3 , 1 × 10-2 and 1 × 10-1 (cm2/v.s) at the donor layer. carrier concentration profile has been studied for 0.4 and 0.5 v junction voltage and for different values of carrier mobility. finally highest external quantum efficiency of 2.413% and maximum power density of 24.13 w/m2 has been obtained for hole mobility of 1 × 10^-1 (cm^2/v.s) and electron mobility of 5 × 10^-1 (cm^2/v.s).
