Abstract

The article considers the problems of formation the light flexible III–V compounds-based solar cell. Approaches of the problems solves were proposed. Was fabricated the light flexible solar cell based on the InGaP/GaAs heteroepitaxial structure. The solar cell weight and size characteristics have been determinate. The solar cell specific weight was 0.51 kg / m2.The bending tests showed that the minimum bending radius of the solar cell is 36 mm. The solar cell current-voltage characteristics were measured for AM0 and AM1.5D spectrum at 28.6°C и 25°C respectively. The efficiency was 23.1% for AM0 and 28.32% for AM1.5D.
