Abstract :
The effects of different module configurations on the performances of multijunctioning (MJ) solar cells in a radiation environment were investigated. Module configuration refers to the electrical circuit in which the subcells of the multijunction cell are wired. Experimental data for AlGaAs, GaAs, InGaAs, and silicon single-junction concentrator cells subjected to 1 MeV electron irradiation were used to calculate the expected performance of AlGaAs/InGaAs, AlGaAs/silicon, GaAs/InGaAs, and GaAs/silicon MJ concentrator cells. These calculations include independent, series, and voltage-matched configurations. The module configuration is found to have a significant impact on the radiation tolerance characteristics of MJ cells.
