| Abstract: | The effect of ultraviolet(UV)radiation on polycrystalline silicon solar cell was stud-
ied. The reflectance spectrum, performance parameter and external quantum effi-
ciency was analyzed by varying exposure time for different fluence of UV radiation.
Reflectance spectrum showed increase for 10 minutes of exposure and starts to de-
crease and come back to nearly original value after 190 minutes exposure. Maximum
potential power (Pmax ) showed no change for all fluence of UV radiation. Short cir-

cuit current density (JSC ) increase from 0.037 cm2 to 0.041 cm2 for 10 minutes of UV
radiation exposure and external quantum efficiency (EQE) of polycrystalline silicon
solar cell showed reduction for 10 minutes exposure and for the rest of fluences of UV
radiation very small change of EQE was observed. |
