Transparent solar cells (TSCs) can be used in systems where conventional opaque cannot applied, such as the glass windows of buildings and sunroofs vehicles. Although extensive research is being conducted on development TSCs, some critical limitations remain, including low power conversion efficiency (PCE), reduction PCE with changes angle incidence light, temperature increase TSC. In this study, we address these issues by selectively applying microscale inverted-pyramidal-structured polydimethylsiloxane to As a result, develop crystalline silicon-based glass-like TSCs 15.8% (at an average visible transmittance 20%). Furthermore, due wide-angle anti-reflection effects, system maintains retention 96% even at incident 50°, film demonstrates radiative cooling effect that reduce temperatures TSC up 16°C.
