英文摘要	The influence of triangular grating used as a light trapping structure on the optical wave propagation within thin-film microcrystalline silicon (mu c-Si:H) solar cells is investigated. A finite difference time domain (FDTD) approach is used to rigorously solve the Maxwell's equations in three dimensions. We apply two parameters of mean surface roughness (S-a) and slope (k) to define triangular structure and study their influence on the absorption of mu c-Si:H. When Se and k are set to 400 nm and 1, respectively, a largest enhancement of absorption is achieved. The optimum short circuit photocurrent (J(SC) of a 1-mu m thick mu c-Si:H solar cell made on such a textured substrate can reach 27.0 mA/cm(2). The carrier generation rate in the mu c-Si:H material is also rigorously analyzed. Finally, we identify some key optical losses in mu c-Si:H solar cells and propose for further optimizing the device design. (C) 2016 Elsevier B.V. All rights reserved.
