| Popis: | 33rd European Photovoltaic Solar Energy Conference and Exhibition; 1379-1382 Herein we report on the development and testing of a high-performance structured AR coating applied to solar glass by means of TOWA’s high-pressure molding technology. This technology allows the application of optically-active structures on glass with unprecedented freedom of geometry and precision. The structured layer with AR functionality were based on a theoretically defined geometry, which then was translated into a mold design. As deduced from the systematic I-V measurements at different angles of incidence, the developed ARC provided a ca. 2.1% rel. gain in ISC at normal incidence and greatly improved light capturing at high angles of incidence as compared to flat glass, but also compared to a typical commercial structured solar glass. The experimentally-derived incident angle dependence was then used to estimate the impact of ARC on annual yield for a typical residential system. Depending on the location and the system orientation the ARC improves the annual yield by 5-7% rel. when compared to a flat glass-black background configuration and by 2-2.5% rel. when compared to a flat glass-white background configuration. Aside from greatly light trapping, the coating could offer additional advantages, like improved aesthetics, protection against mechanical impact, and electrical safety of a module and could benefit such applications as BIPV, automotive PV, portable PV, space-based PV |
