Modeling and Simulation of Photovioltaic Cell with MATLAB for Different Temperature and Different Solar Radiation

Abstract

In this paper the photovoltaic (PV) effect is studied for different Environment parameters (solar radiation and temperature). Modern research focuses on the renewable energy sources such as solar energy. Solar energy can be converted in to electricity by using photovoltaic cells. The photovoltaic system is a mechanism that allows the transformation of solar radiation into electricity (convert photon energy into the form of electrical signals in a PN silicon junction or other material) that we can use for our needs, for example in the electricity supply of an apartment or in the electricity supply of electricity distribution operators in public networks. The PV cells have nonlinear nature, so numerical methods are preferred in these cases. Numerical results are generated by MATLAB software and they are presented graphically. In this study, PV cell specification characteristic curves current-voltage and power-voltage have been obtained for different temperature at constant irradiance and different irradiance at constant temperature. From this graph we can see the effect of irradiance and temperature on the current and voltage. Finally, we have presented power-voltage characteristic curves of photovoltaic cell for different solar radiation in Durres city.
