Performance Research on Photovoltaic/Thermovoltaic Solar System in Building Integrated Photovoltaic (BIPV)

Wei Chen, Yi Wang Bao

Abstract

A novel hybrid photovoltaic/thermovoltaic solar system (PV/TV) was designed with PV cells combined with heat collector and thermoelectric generator. This PV/TV model can collect heat from the solar panels to reduce its surface temperature, and then to generate electricity by using of temperature difference technology and devices. In this paper, electricity generation performance of PV/TV system between April to October was tested and discussed. The application of this system in photovoltaic building was discussed. The results indicate that overall efficiency of this PV/TV system is higher than that of a pure PV system, and about 5%-15% efficiency increase.
