Abstract :
Mesoporus silica dielectrics, which revealed low refractive index (n~1.27), 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 2%.
