Compound semiconductor solar cells have near optimum band gap for solar spectrum, and efficiencies in exess of 20% are expected. (GaAI)As/GaAs heterojunction solar cells have an efficiency over 20%. Recent progress of GaAs solar cells is reviewed with emphasis on the development as a concentrator solar cell and the single crystalline thin film technology. Furthermore, the spectral splitting type and the monolithic cascade type solar cells are also reviewed.
