Study The Effect Of Ultraviolet Radiation On Polycrystalline Silicon Solar Cell

The effect of ultraviolet(UV)radiation on polycrystalline silicon solar cell was studied.rnThe reflectance spectrum, performance parameter and external quantum efficiencyrnwas analyzed by varying exposure time for different fluence of UV radiation.rnReflectance spectrum showed increase for 10 minutes of exposure and starts to decreasernand come back to nearly original value after 190 minutes exposure. Maximumrnpotential power (Pmax) showed no change for all fluence of UV radiation. Short circuitrncurrent density (JSC) increase from 0.037 Arncm2 to 0.041 Arncm2 for 10 minutes of UVrnradiation exposure and external quantum efficiency (EQE) of polycrystalline siliconrnsolar cell showed reduction for 10 minutes exposure and for the rest of fluences of UVrnradiation very small change of EQE was observed.
