Customer ServiceMoreover, the attenuation of the current-limiting unit is smaller. As a result, the total irradiation attenuation increased slightly. Therefore, the quality of the subcell and the current matching of each subcell determine the radiation resistance of the solar cell.
Furthermore, the radiation resistance can be enhanced by reducing the thickness of the base. This is because the displacement damage dose of the incident particles in the solar cell increases as the depth of the incident particles increases.
In general, the degradation due to the particle radiation mostly depends on the sort of particle, its energy and impacting direction, the material of the cell, the active region thickness, and the concentration and type of doping , .
The radiation-induced degradation of PV-cells is due to the defects created by ions or nuclei particles that strike the solar cells’ wafers. The striking particles modify the crystal structure of the semiconductors by ionization or atomic displacements, see Fig. 2 - (a).
When the scanning voltage is fixed, the dark currents of the IMM3J, GaAs, and InGaAs SJ solar cells increase rapidly with increasing irradiation fluence and the dark currents of the IMM3J and InGaAs SJ solar cells increase at the same rate. These results verify the conclusions presented in Figs. 2 (a) – 2 (f). FIG.
With the increase in the irradiation fluence, the spectral response of the GaInP subcell in IMM3J solar cells remains almost unchanged, while the GaAs and InGaAs SJ subcells degrade significantly and the InGaAs subcell is degraded more. This is mainly due to the correlation between the structure and physical effects of radiation.
