In order to study the performance of flexible solar cells,low-weight flexible Ga In P/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 of175 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.
