Study and optimization of heterojunction silicon solar cells

Abstract

This paper reports on the optimization of fabrication parameters of a heterojunction silicon solar cell using computer simulations and comparison of the simulation data with experimental results. The optimization of the photovoltaic devices was performed with respect to the thicknesses of amorphous silicon layers. As a result, a reasonable correlation between the simulation data and experimental results is observed within the acceptable margin of error with respect to heterojunction silicon solar cells with efficiency exceeding 20%.
