However, PM2.5 leads to adverse effects on the PR of a-Si and CdTe systems since a negative trend with an average R of 0.83 is observed throughout the considered experimental period.
In contrast, the amorphous silicon and cadmium telluride PV systems with a narrower spectral response range show a decreasing trend in the performance ratio over the experiment.
Moreover, an increasing trend in the performance ratio of monocrystalline silicon, polycrystalline silicon, and copper indium gallium selenide PV systems with the increase of PM2.5 concentration is observed.
