摘    要:为了研究柔性太阳能电池的性能,通过太阳能电池减薄工艺制备出轻质柔性Ga In P/Ga(In)As/Ge三结太阳能电池芯片。尺寸为40 mm×60 mm的电池芯片重量为0.7 g,仅为常规175μm厚度电池重量的30%。验证了柔性电池工艺的可行性,制得的柔性电池转换效率达到了30.64%,同常规厚度电池十分接近。对比测试了两种样品不同温度下的暗电流曲线,拟合了两种电池样品的温度系数,结果表明:电池的温度系数与衬底类型无关,只与电池PN结本身相关。

关 键 词:空间太阳电池  柔性太阳电池  温度系数

Abstract:In order to study the performance of flexible solar cells,low-weight flexible GaInP/Ga(In)As/Ge triple-junction solar cell was fabricated by thinning process.The weight of the 40 mm×60 mm solar cell chip is 0.7 g, which is only 30% of the conventional solar cell with the thickness of 175 μm.The conversion efficiency of this kind of solar cell is 30.64%, closing to that of the normal thickness chips.The results show the feasibility of this thinning process.For both samples with different chips thickness, under different temperature, the dark I-V curves were measured and the temperature coefficients were fitted.It can be concluded that the temperature coefficient is linearly correlated to the PN junction rather than the substrate type.
Keywords:space solar cell  flexible solar cell  temperature coefficient
