Van allen radiation belt
范艾倫輻射帶 -
Van allen belt
范艾倫輻射帶 -
At present, the solar cells used on space aircrafts are still mainly si and gaas solar cells. however, the radiation resistance ability of these two materials is poor. since the photoelectric conversion efficiency attenuates rapidly with the radiation, the lifetime of si and gaas solar cells is short and their stability is not satisfied for space applications at van allen belt
目前國內外用於航天器上的太陽電池主要為si和gaas太陽電池,但這兩種材料的抗輻射能力較差,其光電轉換效率由於高空輻射衰減很快,因而壽命短,穩定性差,不能滿足用於vanallen強輻射帶的空間應用需要。
