The aging of the solar cell in space generally designates the degradation owing to the irradiation of electrons and protons for a given period. The degradation in this model is assumed to be caused by the cumulative set of defects created by proton and electron irradiations. The following equation (10) models the degradation rate due to the accumulation of irradiation defects in the
Aging of perovskite solar cells has been considered as a negative process toward degradation of efficiency.

Though gallium arsenide (GaAs) solar cells are proven to be relatively stable in space working conditions, they are prone to the effects of aging, which deteriorate their characteristics.

In general, solar PV has a 25-year expected lifespan. Solar PV modules will not survive for this long in the majority of cases. Aging is the term that is used to describe the degradation of a PV module before its expected lifespan [8, 9]. The factors that underlie the reduction in the lifetime of a PV module can be defined as aging factors.

As perovskite solar cells approach maximum theoretical performances, stability becomes the next big challenge. However, ion migration, causing the infamous hysteresis effect, required measurement standards for efficiency. Analogously, it is now necessary to develop stability standards or else another "wild west" period, without comparable stability data, may
Given their efficiency by the end of the testing period of more than 68 days, the extrapolated intrinsic lifetime of the solar cells worked out to be an astonishing 27,000 years. Lead author, Quinn Burlingame, tested similar cells at a solar station in the Negev desert.
The aim of this paper is to investigate the influence of aging on the main characteristics of solar cells. To simulate and accelerate the effects of aging, solar cells were exposed to the different doses of ionizing radiation. Efficiency dependence on the ideality factor. Dependence of the series resistance on the absorbed dose.
One of the key issues that contribute to the early aging of solar PV is discoloration. PV cells cause discoloration by altering the material’s color. The encapsulant ethylene-vinyl acetate (EVA) corrodes as a result of this incident. EVA is a substance that transmits radiation well and degrades slowly under sunshine.
The degeneration of solar cells is brought on by their discoloration, which can lead to irreversible cell degradation and accelerate aging [67, 68, 69]. This degradation is often seen after a prolonged period of exposure and worsens over time. Figure 3 illustrates the aging process due to discoloration.
Aging is the term that is used to describe the degradation of a PV module before its expected lifespan [8, 9]. The factors that underlie the reduction in the lifetime of a PV module can be defined as aging factors. The roots of this degeneration are aging-related issues.
Aging of the photovoltaic cell and the various types of degradation have several repercussions on cell’s electric characteristics . Thus, its parasitic resistances are affected (with an increase in series resistance, R s, and a decrease in shunt resistance, R sh) as well as its transmittance (τ) that suffers a reduction.
Kazem et al. evaluated the effect of aging on a grid-connected photovoltaic system by investigating a 1.4 KW PV plant exposed for 7 years; the results indicate that the efficiency of the PV modules decreased by 5.88%, and it is also notable that the degradation rate was severe during the summer months because of the dust density .
