Multilayer Antireflection Coatings for Cover Glass on Silicon Solar Modules

The cover glass on solar modules provides protection for the underlying cells but also leads to two forms of power loss: reflection losses and soiling losses. In this work, we report design a broadband multilayer antireflection (MAR) coating designed use with silicon its advantages over commercial porous SiO $_{2}$ sol-gel coatings. six-layer comprising ZrO has then been deposited using high-rate pulsed dc magnetron sputtering. are reduced by 2.4% absolute compared uncoated glass, whereas coatings reduce 2.2%. increased light reaching cell improves short-circuit current density ( J notation="LaTeX">$_{{{sc}}}$ ) spectral response, which increases conversion efficiency from 17.1% 17.5%, relative increase 2.34%. is environmentally robust abrasion resistant, AR susceptible damage water ingress. sputtering process used fabricate MAR high throughput applications most major manufacturers.
