Research on heat-transfer characteristics of solar cells and heat exchanger combined system and its optimization

The study of solar heat exchanger is committed to enhancing the thermal efficiency of the existing system to achieve a result that little electricity is required and clean energy is applied to cool in summer and heat in winter. It makes full use of sunlight energy, through photovoltaic and solar thermal effects to produce heat and power generation at the same time. The gravity heat pipe is installed on the back surface of a solar panel, so that heat from the solar panel can be transferred to the house. Thus, the photovoltaic efficiency of the solar cell is obviously improved without changing its solar board structure.
