Enhanced solar-light transmission by broadband anti-reflective structure with mesoporous silica of low refractive index

Abstract

Mesoporus silica dielectrics, which revealed low refractive index (n similar to 1.26), were introduced together with Si3N4 layers to be double-layer-based graded-refractive-index ant-reflectors for silicon solar-cells. Enhanced solar-light transmission increased conversion efficiency of Si solar panels by 4%.
