Abstract

In this paper

the analyzed and optimized of photovoltaic properties of a-Si:H(p)/i-a-Si: H/c-Si(n) heterojunction solar cell are simulated by the AFORS-HET software. Mainly compared the a-Si:H(p) uniformly doped layer and the surface doping concentration

gradient doping case of photovoltaic properties. The photovoltaic properties comparative and optimized were simulated by the AFORS-HET software. The conversion efficiency can reach 22.32% by gradient doping. Compared with the uniform-doping mode

the gradient doping not only introduced an additional electric field

but also optimized the energy band

spectral response and recombination rate. The simulation results show that the gradient doping can improve the photovoltaic performance of the solar cells efficiently.
