摘要

Solar cells operating in harsh conditions such as extraterrestrial environment suffer from ionizing UV irradiation from the sun and radiation damages from high-energy particles. Titania (TiO_2) can achieve high trans-mittance in the visible and near-infrared while efficiently blocking UV irradiations. Cerium-doped yttrium aluminum garnet (YAG:Ce) is commercially used as an efficient spectral downconverter in white-light LEDs, and it has also been studied for its potential as a radiation-withstanding scintillator. We propose TiO_2/YAG :Ce thin films utilizing TiO_2's UV cut-off properties as well as YAG:Ce's downshifting properties as both multipurpose protector and performance enhancer for solar cells. photovoltaic; protective coating; downconversion; space application.
