Description
Summary:Problems arising in fabrication of lightweight flexible solar cells based on heteroepitaxial A III B V structures with substrate etching are discussed. Possible solutions are proposed. A tandem lightweight flexible solar cell based on a heteroepitaxial InGaP/GaAs structure was fabricated. Its mass and dimensional characteristics were determined, and bending tests were performed. The specific mass of this solar cell was 0.51 kg/m 2 , and the allowable bend radius was 36 mm. Its current–voltage curves were measured for the AM0 and AM1.5D spectra at 28.6°C and 25°C, respectively. The cell efficiency was found to be 23.1% and 28.3%.
