A simple approach to block incidence of Ultraviolet radiations on PV Module

Photovoltaic cell is not a new technology, as it has been the topic of interest for researchers since its invention who have been working to make it more feasible, sustainable and efficient. Photons energize electrons in solar cells, which generate electricity, but the short wavelength part (i.e., ultraviolet radiations) of solar spectrum increases cell temperature and also degrade solar panel's encapsulant which decreases PV module's performance along with a reduction of its life. So in this paper, a simple mechanism to block ultraviolet (UV) radiations incidence on PV module, is presented and its effect on PV module is calculated. Analytical results show a reduction in cell temperature along with slightly decrease in output power. This research work can be used for almost all types of PV modules available today to enhance their life.
