一维衍射光栅和一维光子晶体组成的硅薄膜太阳能电池背反射器
Back Reflectors of Thin-film Silicon Solar Cells Consisting of One-dimensional Diffraction Gratings and One-dimensional Photonic Crystal
摘要
Abstract
We designed a type of reflector that consisted of one-dimensional diffraction gratings and one-dimensional photonic crystal. It can be used for thin-film silicon solar cells. The structure parameters were optimized by Legendre polynomial expansion method, and the reflectivity at the range of 400 ~ 1 200 nm was calculated. Under the high reflectivity one-dimensional photonic crystal, the propagation path of the photon can be extended and absorbed in the battery. The results show that the diffraction grating and a back reflector in the photonic crystal structure are efficient at the range of 750 ~ 1 100 nm. Back-reflection layer can greatly improve the light harvesting capacity and enhance the conversion efficiency of solar cells.关键词
