Losses in solar cells can result from a variety of physical and electrical processes, which have an impact on the system's overall functionality and power conversion efficiency. These losses may happen during the solar cell's light absorption, charge creation, charge collecting, and electrical output processes, among others.
The amount of solar radiation energy reflected by the device can have a substantial influence on this loss, which affects the efficiency of the solar cell as a whole.
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 radiation damage is uniform throughout a solar cell, the relativeeffectiveness of various energy particles is the same when measured by thediffusion length damage coefficients, or critical fluences determined by cellparameters such as Isc, Voc, orPmax.
Protons in theenergy range from 1.5 to 3 MeV produce a maximum in relative radiation damagein silicon solar cells. The relative damage to silicon solar cellVocand Pmaxdue to low energy protons ismore severe than that exhibited by Isc. Proton damage in silicon solar cells can be normalised to the damage producedby protons of one energy.
