“…Nevertheless, the fact that no degradation is observed for a dose of 10 16 e À cm À2 implies that PSCs are promising candidates for space applications. These findings compare favorably with results obtained under similar conditions for Si, [23] GaAs, [24] and InGaP/InGaAs/Ge, [25] single and triple junction cells that show a larger decrease in the overall efficiency (10-30%). Other thin film technologies such as CdTe and Cu(ln,Ga)Se (CIGS) show similar stability than our PSCs.…”

Metal halide perovskite solar cells (PSCs) are of interest for high altitude and space applications due to their lightweight and versatile form factor. However, their resilience toward the particle spectrum encountered in space is still of concern. For space cells, the effect of these particles is condensed into an equivalent 1 MeV electron fluence. The effect of high doses of 1 MeV e‐beam radiation up to an accumulated fluence to 1016 e− cm−2 on methylammonium lead iodide perovskite thin films and solar cells is probed. By using substrate and encapsulation materials that are stable under the high energy e‐beam radiation, its net effect on the perovskite film and solar cells can be studied. The quartz substrate‐based PSCs are stable under the high doses of 1 MeV e‐beam irradiation. Time‐resolved microwave conductivity analysis on pristine and irradiated films indicates that there is a small reduction in the charge carrier diffusion length upon irradiation. Nevertheless, this diffusion length remains larger than the perovskite film thickness used in the solar cells, even for the highest accumulated fluence of 1016 e− cm−2. This demonstrates that PSCs are promising candidates for space applications.

“…Therefore, radiation resistance is also a critical index to evaluate the quality of space solar cells. The main reason for the performance deterioration of space solar cells is the irradiation of high-energy particles, that include electrons (energy up to 10 MeV) and protons (energy up to several hundred MeV) from the earth's radiation belt, as well as solar cosmic rays (energy up to GeV) [86]. When these high-energy particles collided with the cell materials, the transmitted energies cause the lattice atoms to shift their original positions and form displacement damages, and, consequently, the diffusion length of minority carriers decreases and the performance of solar cells is degraded [87].…”

The demands for space solar cells are continuously increasing with the rapid development of space technologies and complex space missions. The space solar cells are facing more critical challenges than before: higher conversion efficiency and better radiation resistance. Being the main power supply in spacecrafts, III-V multijunction solar cells are the main focus for space application nowadays due to their high efficiency and super radiation resistance. In multijunction solar cell structure, the key to obtaining high crystal quality and increase cell efficiency is satisfying the lattice matching and bandgap matching conditions. New materials and new structures of high efficiency multijunction solar cell structures are continuously coming out with low-cost, lightweight, flexible, and high power-to-mass ratio features in recent years. In addition to the efficiency and other properties, radiation resistance is another sole criterion for space solar cells, therefore the radiation effects of solar cells and the radiation damage mechanism have both been widely studied fields for space solar cells over the last few decades. This review briefly summarized the research progress of III-V multijunction solar cells in recent years. Different types of cell structures, research results and radiation effects of these solar cell structures under different irradiation conditions are presented. Two main solar cell radiation damage evaluation models—the equivalent fluence method and displacement damage dose method—are introduced.

Defect‐assisted recombination often restricts the performance of photovoltaic devices, and in order to mass‐produce reliable solar cells, low‐cost express methods are in demand, which could monitor contamination during the process of manufacture. In our work, we applied the deep learning‐based approach for estimating iron concentration in silicon solar cells by using ideality factor. The simulation of solar cells with the back surface field design for generating labeled training and test datasets was performed using SCAPS‐1D software. Our results demonstrate that deep neural networks can predict iron concentration using the ideality factor, temperature, base‐thickness, and doping level of solar cells. Our simulation showed smaller prediction errors at high doping level, low temperature, and the two values of ideality factor: the first one for structures containing only iron interstitial atoms and the second for structures where Fei and iron–boron pairs coexist. The proposed method was tested on real silicon structures.
