In photovoltaic power generation, only less than 18% of incident solar energy of the solar cell is converted into electric energy, and most of the solar energy is absorbed and then converted into heat energy, so that the temperature of the solar cell is increased. The temperature of the solar cell rises by 1 ℃, and the conversion efficiency is reduced by 0.25-0.5%. Therefore, how to reduce the temperature of the solar cell and recycle the generated heat becomes a new research field. Related research began at 1978 with the earliest concept of designing PV/T solar energy systems by two academists, Kern and Russell, in the united states.
