Overview and Loss Analysis of High-Efficincy III-V Compound Single-Junction Solar Cells

The III-V compound solar cells have contributed as space and concentrator solar cells and are important as sub-cells for multi-junction solar cells. This paper reviews progress in III-V compound single-junction solar cells such as GaAs, InP, AlGaAs and InGaP cells. In addition, analytical results for non-radiative recombination and resistance losses in III-V compound solar cells are shown for further understanding and reducing major losses in III-V compound materials and solar cells.
