Abstract

At present, the research and development of PVT modules by researchers and engineers worldwide is still in the stage of small-scale production and research and development. Most PVT modules use ordinary photovoltaic cells. In order to ensure their best operating efficiency, the output hot water temperature is generally not more than 30°C. To obtain high temperature hot water, secondary heating is required, such as using heat pump, so the overall system cost is high. Based on the above problems, this paper studies and develops a new PV-thermal integrated module, re-optimizes the overall structure, selects the characteristic high-temperature resistant crystalline silicon photovoltaic cell (black silicon) and solar special heat-absorbing coating to improve the operating temperature of the PVT module, and uses graphene heat conductive material to increase the contact area of heat conduction and heat transfer, which is packaged and processed. After a series of experimental tests, the operating temperature of the PVT module reaches 60°C, and it can stably obtain high-quality hot water above 50°C. The PVT module can work under high temperature conditions for a long time, effectively improving the overall energy conversion efficiency of the system, and the generated hot water can directly meet the needs of daily life and space heating without secondary heating, has a good market development prospect.
