摘要：

This article studied the a-Si:H solar cell with a randomly rough surface for high-power conversion efficiency. Both experimental result and simulation modeling are presented. A full three dimensional numerical modeling program including finite difference time domain for optics and Poisson and drift-diffusion solver for electronic simulation are used and verified by experimental results. The influences of surface recombination, junction recombination, absorption, influences to V-oc, and fill factor are analyzed to find the balanced condition. The simulation results show the optimized absorber thickness is around 150 nm and the major non-radiative loss region is analyzed. The optimized texture condition is also studied in this paper.
