【摘要】 对 Al Ga As/Ga As太阳电池进行了质子辐照和热退火实验 .质子辐照的能量为 32 5 ke V,辐照的剂量为 5×10 1 0— 1× 10 1 3cm- 2 .实验结果表明 ,质子辐照造成了 Ga As太阳电池光伏性能的退化 ,其中短路电流的退化比其它参数的退化更为明显 .退火实验结果表明 ,2 0 0℃的低温退火可以使得辐照后的电池的光伏性能得以部分恢复 .此外 ,实验结果还指出 ,在 Ga As太阳电池表面加盖一层 0 .5 mm的硼硅玻璃盖片可以明显地减少质子辐照对 Ga As太阳电池性能的损伤更多还原

【Abstract】 The investigation on proton irradiation and thermal annealing of AlGaAs/GaAs solar cells has been reported.The energy of the proton irradiation is 325keV and the fluences are ranging from 5×10 10 to 1×10 13 cm -2 .It is demonstrated that the irradiation-induced degradation in the photovoltaic performance of the solar cells exists mainly in the short circuit current and the irradiation damage can be partly recovered by low temperature annealing at 200℃.In addition,it is found that the borosilicate cover glass has an obvious protection effect against the proton irradiation.更多还原
