In this paper, the possibility of using commercial low-power photovoltaic cells batteries as sensors for the estimation of the gamma radiation dose in a certain point in space and for certain
This means that thin-film solar panels, which are much cheaper to produce, are getting more efficient. 1.12 PV Modules. A PV module or panel is a grouping of PV cells. The voltage generated by a single PV cell is
UV radiation accelerates the aging process of the polymer at the initial stage. Therefore, UV radiation is a major factor to affect the lifetime of backsheets, which should be considered when estimating the service life of
The results show that the sunshine duration is an important factor affecting the solar radiation received by photovoltaic panels. In regions from 66°34′N to 66°34′S, intelligent

Exposure of PV materials to UV radiation in an environmental chamber using highly UV transmissive glass allows UV doses equivalent to 20 years of exposure (relative to stress behind 3.18-mm-thick Ce-doped glass) in about 6 months. This allows reasonable evaluation of PV materials.
Similarly, IEC 62108 requires a “UV Conditioning Test” consisting of 50 kWh/m 2 below 400 nm. This is equivalent to about 180 days real-time exposure. The existing qualification tests do not nearly provide assurance that a PV module will withstand 20 or more years of UV radiation.
With the exception of the Staebler Wronski effect in amorphous Si and similar transient effects in copper indium gallium selenide-based PV cells , , , the UV radiation principally acts to degrade the polymeric materials used in PV modules.
It can embrittle the polymer and cause the loss of the mechanical property of backsheets, affecting the stability and the lifetime of the entire PV modules. (18) Thus, the effect of UV radiation on the lifetime of backsheets should be considered.
Based on this principle, solar PV cells have been studied as radiation dosimeters in some applications. 1–3 Different from a semiconductor gamma-ray detector, a solar cell operates under zero external bias voltage, and thus, has an extremely thin depletion region that is inefficient for gamma-photon interception.
“Historically, the harmful effects of UV radiation have largely been associated with the aging of module packaging materials and have led to encapsulant discoloration, delamination, and backsheet cracking,” the group said. “Solar cell performance is also adversely affected by UV radiation through the generation of surface defects.”
