Hybrid photovoltaic and thermal (PV/T) module can generate both thermal and electrical energy and thus achieve a higher overall solar efficiency compared to the independent solar thermal and PV modules of same sizes. However, electrical efficiency of the PVs falls with the rise of the temperature of PV cells which has affected the enhancement of energy performance of the PV/T modules. Recently we found an interesting physical phenomenon that indicates at a specific non-uniform temperature field (i.e. Gaussian), the PV cells in a PV/T module can achieve a significantly higher electrical efficiency 1.978% and 1.653% compared to the anti-Gaussian and uniform temperature fields. This finding creates an opportunity to enhance the energy performance of the PVs in a simple, measurable and cost-effective way.
