Abstract

Silicon solar cells are much of interest as the best possible way to use most abundant energy on the earth. The silicon heterojunction solar cell consists n -type nanocrystalline emitter and p-type crystalline base. Wafer thickness is the major contributor in cost to power conversion ratio. Solar conversion efficiencies are compared at different thickness. The study of the solar cell is done by using one-dimensional solar cell simulation software PC1D. The efficiency is observed under ONESUN, AM1.5G solar radiation, and constant intensity of 0.1 W/cm2 . The simulation results show 20 µ thickness solar cells is the best in cost to power conversion ratio with the short circuit current of 3 A with open circuit voltage of 0.7818V which is quite high in the range of 20 µ thickness. The fill factor(FF) is 0.8578 with overall solar cell efficiency (Ƞ) of 20.14%..
