Method of integrating light-trapping layer to thin-film solar cell

摘要

A light-trapping layer is integrated into a thin-film solar cell. It is integrated as a light-inlet layer, an intermediate layer or a shaded layer with nano-particles embedded in a transparent or non-transparent conductive film. Thus, light stays longer in an absorption layer with photocurrent increased; defects of interface between the absorption layer and the nano-material are decreased; anti-reflective effect to inlet light is enhanced; and a good integrity and a good reliability for long-time light-shining are obtained.
