RESUMO:
Over the years, the contribution of photovoltaics energy to an eco-friendly world is continually increasing and its costs reducing. In PV technologies, the solar cell temperature and incident solar radiation are the main factors that affect their behaviors. The focus of this work will be the temperature, in view of the few number of investigations currently available in literature, which cover simultaneously all aspects of the temperature influence on performance parameters of solar cells. Therefore, to bridge this gap on understanding this influence, a study on the impact of cell temperature on the performance parameters of silicon solar cell is undertaken. The experiment will be carried out using a mono-crystalline silicon solar cell with the temperature in the range 25–80 °C at constant light intensity of 1,000 W/m2, employing a solar simulator (SOLSIM) developed by the INPE and adapted by the author. In this work, the main existing research works on PV cell model parameter estimation problem are classified according to number of parameters, parameters’ extraction, translation equations and PV technology. The existent models were discussed pointing out its different levels of approximation. A qualitative comparative ranking was made and four models were found to be the best ones to emulate PV cells per the aspects considered. From this selected group, an equivalent circuit model was chosen to be used in the solar cell performance parameters extraction. It was made a brief review of the various existing mathematical relationships involving the influence of temperature over solar cells. A possible solution to mitigate the efficiency reduction caused by the temperature is presented. Such solution is expected to improve therefore the performance of PV devices.
