The behaviour of a typical single-crystal Si solar cell under high intensity of electric field

The effect of high intensity of electric fields on the operation of a single-crystal Si solar cell was investigated in this work. A single-crystal Si solar cell was irradiated by spontaneous and stimulated light sources. Firstly, a triac-lamp having a tungsten filament and green, yellow, red and blue LEDs from the spontaneous light sources were used to irradiate the solar cell exposed to a high-intensity electric field EDC. Later, as a stimulated light source He–Ne laser with λ = 633.8 nm and P = 1 mW was utilized, and the behaviour of the solar cell exposed to the electric field EDC ranging from 100×103 to 500×103 V/m was studied. The results showed that the Voc value of the solar cell irradiated by the two light sources mentioned above decreased due to the electric field.
