Abstract:
This study is aimed at to find changes that occur on electrical characteristics for monocrystalline silicon solar cells when exposed to laser light continuous wave mode (CW) at different time periods. Experimental results showed that most output values of the solar cell parameters were increased after irradiation for a period of 15 minutes, then began declining gradually increase when the irradiation of up to less than the value before irradiation values also the values of the internal parameters of the sample were increased according to the irradiation time, this increase also contributed to the decrease in the efficiency of the solar cell conversion. The increase in parameter values for the solar cell when irradiation went out for a period of 15 minutes, due to the short-term radiation exposure, while the values decreased to increase the period of exposure to radiation due to changes in crystal structure resulting from the defect and blemishes caused by prolonged exposure to radiation that.
