A full 3D numerical modeling program developed by our group including 3D FD-TD for optics and 3D Poisson and drift-diffusion solver for electronic simulation are used to model the characteristics of a textured solar cell. The balance between the optical and electrical performance of the a-Si:H solar cell is studied in this work. For model verification, a solar cell with high 9.23 % power conversion efficiency is used to examine the model and parameters. This article figured out the electrical limit for the a-Si:H solar cell and studied the influence of different roughness scales. © 2014 SPIE.Amorphous silicon; Numerical simulation; Surface roughness; Textured surface; Thin film solar cell[SDGs]SDG7Amorphous silicon; Conversion efficiency; Numerical models; Photonic devices; Silicon; Solar cells; Surface roughness; 3-D numerical modeling; Electrical performance; Electronic simulation; Power conversion efficiencies; Randomly rough surfaces; Textured surface; Thin film solar cells; Three dimensional simulations; Computer simulationconference paper10.1117/12.20393162-s2.0-84901788099
