| Abstract: | The concentrated photovoltaic-thermoelectric hybrid system (CPV-TE) increases the light intensity by concentrating, which
enhances the temperature difference between the two sides of the thermoelectric module to improve the thermoelectric efficiency. However, concentrating also brings problems such as the excessive temperature of the photovoltaic cell. Improving the heat transfer capacity of the cold end is an effective method to reduce the photovoltaic temperature and improve the temperature difference between the two sides of the thermoelectric module. The effects of cooling temperature at the cold end, cooling water flow rate, and different cooling media on the CPV-TE hybrid system were investigated under different light intensities. The result shows that reducing the cooling water temperature and increasing the medium flow rate could reduce the temperature of the photovoltaic cell and increase the temperature difference between the two sides of the thermoelectric module, thereby improving the photoelectric conversion efficiency and the thermoelectric efficiency. Moreover, the cooling effect is enhanced by using the MWCNT-water nanofluid as a heat exchange medium to improve the overall output of the system. |
