Investigation of the Optical Absorption of a-Si:H Solar Cells on Micro- and Nano-Textured Surfaces
Abstract Light trapping is essential for thin-film silicon solar cells due to their thin absorber layers. Textured surfaces are widely used to scatter light, thereby increasing the pathlength of light in these solar cells. In a-Si:H solar cells...
