综合采用太阳跟踪聚光技术和热工原理,设计加工了一种聚光型光电光热一体化装置,并对其进行了实验研究。结果表明,采用层压技术将电池片与热交换器组合在一起,不仅可有效降低电池片的工作温度、确保其光电转换效率、延长其使用寿命,而且可获得一定温度的热水。通过集热板的二次加热,可获得更高温度的热水,从而实现高效、低成本太阳能光电-光热的综合利用。同时,研究还表明,气候条件或空气质量对实际聚光比影响较明显,但对该装置的光电转换效率以及所获得的热水温度无显著影响。
Based on the combination of solar tracking and thermal technology, a concentrating photovoltaic and thermal integration device was designed and fabricated, and its experimental research was carried out. The results show that the use of lamination technology to combine the cell and the heat exchanger can not only effectively reduce the working temperature of the cell, ensure its photoelectric conversion efficiency and prolong its service life, but also obtain hot water at a certain temperature. Through the secondary heating of the collector plate, hot water of higher temperature can be obtained, so that the comprehensive utilization of high efficiency and low cost solar photovoltaic-light and heat can be realized. At the same time, the study also shows that the climatic conditions or air quality have an obvious effect on the actual concentration ratio, but have no significant effect on the photoelectric conversion efficiency of the device and the obtained hot water temperature.
