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.
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.
Throughout the years, the evolution of solar cells has marked numerous significant milestones, reflecting an unwavering commitment to enhancing efficiency and affordability. It began in the early days with the introduction of crystalline silicon cells and progressed to thin-film technology.
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.
The presence of dislocations affects the epitaxial quality of the InGaAs subcell to some extent and ultimately affects the performance of solar cells. 11,12 SHARP developed an IMM GaInP/GaAs/InGaAs solar cell with a conversion efficiency of 35.8% in the AM1.5G spectrum.
The electrical parameters of the solar cells degraded logarithmically with changes in the irradiance fluence. According to the dark IV analysis, the IMM3J solar cell and InGaAs SJ subcell exhibited the same increase in the dark current. The EQE analysis revealed that the spectral response of the GaInP subcell remained nearly unchanged.
