Effect of Junction Cell Temperature and Geographical Coordinates on The Electrical Performances of a Photovoltaic Module

After the absorption of the photons, during the photovoltaic conversion process, one part of the radiation remains unabsorbed causing the cell to overheat and thus a drop in e ciency. The purpose of this study is to explore the e ect of junction temperature, geographic coordinates as well as the season on the electrical performance of the photovoltaic cell. The results obtained show that the junction temperature has an e ect which is not favorable on the electrical e ciency of the module for high temperatures around midday which is of 11% however it reaches 14% for low temperatures in the morning. Geographical coordinates at di erent altitudes, have no e ect on the energy produced from the module, but the e ect of the season on the efciency con rms the previous results, that, the e ciency is good for low temperatures. The results are obtained by simulation, through a computer code in FORTRAN language, designed for this purpose.
