【摘要】 为了满足航天器电源系统对太阳电池的不同要求,研制多种性能和多种结构的新型太阳电池是十分必要的。研制了砷化镓(GaAs)太阳电池、薄型BSFR硅太阳电池、绒面薄型BSFR硅太阳电池等新型空间用太阳电池,并将这些太阳电池与常规BSFR硅太阳电池和BSR硅太阳电池的电性能和抗辐照性能进行了比较,砷化镓太阳电池有着最高的性能和最好的抗辐照性能,单晶硅太阳电池的电性能和抗辐照性能由电池的厚度,表面形貌及基体材料的电阻率决定。展望了这些太阳电池的空间应用前景。更多还原

【Abstract】 It is very important and necessary to develop different space solar cells which have different performances and structures for varied space missions. Some new types of space solar cells were developed, including single junction GaAs solar cells, thin BSFR(Back surface field and reflector) silicon solar cells, textured thin BSFR silicon solar cells. All these solar cells were suffered to 1 MeV electron radiation experiment. The GaAs solar cells had the best performances and radiation resistance characteristic, which are determined by the thickness, surface structure and substrate material resistivity of the cells. And all of their application prospects were expected .更多还原
