Radiation effects in solar cells

Imaizumi, Mitsuru*; Oshima, Takeshi

Radiation effects in solar cells are described. Degradation behavior of space solar cells, such as silicon solar cells and InGaP/GaAs/Ge triple-junction solar cells, due to high-energy electrons and protons are elaborated in the presentation. Space solar cell design technology is also explained. In addition, technologies for practical application of solar cells in space including methodology for radiation protection and degradation prediction are interpreted. Furthermore, recent development status of state-of-the-art space solar cells is introduced.
