Abstract

Mesoporus silica dielectrics, which revealed low refractive index (n~1.26), were introduced together with Si3N4 layers to be double-layer-based graded-refractive-index anti-reflectors for silicon solar-cells. Enhanced solar-light transmission increased conversion efficiency of Si solar panels by 4%. The degradation in photovoltaic efficiency of solar panels that were covered with Si3N4/MS anti-reflectors was as small as 0.54 % after 60 hours of irradiation. MS films revealed wide band-gap of 6.4 eV and, therefore, negligible absorption in the solar spectrum, in response to highly stable photovoltaic efficiency during long-term irradiation.
