 Potential application of electrical performance enhancement methods in PV/T moduleYashun Lu and Guiqiang Li Energy, 2023, vol. 281, issue C Abstract: Hybrid photovoltaic/thermal (PV/T) modules have been proposed to generate more electricity and heat, which can improve the solar energy conversion efficiency per unit area. However, the photovoltaic (PV) efficiency of PV/T modules decreases as the PV cell temperature increases, which significantly affects the solar energy conversion efficiency of PV/T modules. Here, four temperature profiles (uniform, single-Gaussian, double-Gaussian, multi-Gaussian) are proposed on the PV cell surface by adjusting the heat transfer arrangement for the PV cell cooling duct in the PV/T module. Compared with the uniform temperature profile, the multi-Gaussian temperature profile PV cell efficiency increased by 1.292%; the single-Gaussian temperature profile PV cell efficiency decreased by 4.308%. The results show that for PV cells in the PV/T module, different temperature profiles lead to great differences in electrical performance, and a nonuniform temperature profile can be set to improve their electrical performance.
