the complexity of the internal heat transfer (there is heat con-duction, convection and radiation heat transfer) in PV/T systems, the temperature of solar PV panel should not be uniform, i.e. the temperature of solar PV panel increases along the fluid flowing direction, leading to non-uniform cooling of solar PV cells, which is unfavorable of photoelectric conversion efficiency enhancement; meanwhile, owing to the inhomogeneity of the temperature of solar PV cells, it is inconvenient for temperature control. For these rea-sons, a heat pipe PV/T hybrid system has been put forward in this paper. For one thing, it can make full use of the isothermal perfor-mance and adjustable operating temperature of the heat pipe; for another, it takes advantage of efficient heat transfer performance of heat pipe. Such a PV/T hybrid system not only ensures the temper-ature of solar PV panel uniform thus improving the photoelectric conversion performance, but also makes the operating temperature of solar PV cells adjustable. Recently, Pei et al. [13] have designed a heat pipe PV/T system that can be used in cold regions without freezing when compared with the traditional water-type PV/T sys-tem. A dynamic model was developed to predict the performances of the heat-pipe PV/T system through simulation and experimental studies.
