Abstract
In this work an innovative antireflection coating technology for photovoltaic modules based on remote plasma-enhanced chemical vapour deposition of porous SiO 2 films is presented. We show that the proposed technology has the potential to significantly improve the performance of photovoltaic modules by effectively reducing the optical losses of the air/glass interface. As a result, the transmission of a glass pane measured at a single wavelength was increased from 91.7% to 100% by a single-layer porous SiO 2 antireflection coating on both sides of the glass pane. Furthermore, a double-layer porous SiO 2 antireflection coating on both sides of the glass pane increased the transmission weighted with the AM1.5G spectrum in the 400–1150 nm wavelength region from 91.6% to the remarkably high value of 99.4%.
