Modeling and Experimental Validation of a New Hybrid Photovoltaic Thermal Collector

A calorific energy is generated during the photovoltaic conversion of the solar module, which increases the temperature of the cell and will cause a fall in its electric output. This phenomenon is, on one hand, due to the partial unabsorptive solar radiation, which constituted the origin of the cell...

Zusammenfassung:A calorific energy is generated during the photovoltaic conversion of the solar module, which increases the temperature of the cell and will cause a fall in its electric output. This phenomenon is, on one hand, due to the partial unabsorptive solar radiation, which constituted the origin of the cell's heating, and on the other hand, due to the Joule effect caused by the passage of the photo-electrical current generated in the external circuit. This heating, harmful for the photovoltaic cell output, involved many research efforts to limit its effects by evacuating this heat. There was also the idea to exploit this phenomenon by the combination of the photovoltaic module with a thermal system to form the photovoltaic thermal (PVT) hybrid collector, which will generate, at the same time, electricity and heat. In this paper, the design of a new type of PVT collector is described through its numerical modeling and experimental study. This novel collector constitutes a new technical approach to maximize the total output of conversion with lower cost compared to the traditional hybrid collectors.
