Abstract

After several years of using solar cells, its electrical parameters are degraded. in this paper, to simulate of aging, solar cells were exposed to the different doses of gamma radiation. The (I–V) characteristics of silicon solar cells were studied before and after gamma irradiation. Experimental results showed that the electrical parameter of solar panel such as short circuit current, open circuit voltage, and efficiency decrease with the increase of the gamma doses. As well as, dependence of Voc and Isc according to the absorbed dose for different illumination levels has been investigated.

Keywords
