Investigation on the performance of a novel compound parabolic concentrator coupled photothermal and photoelectric energy suppling
摘要
Abstract
The instantaneous heat collection of the non-tracing compound parabolic concentrator is greatly affected by the incident angle.Therefore,in this paper,the PV module with a mirror on its backside was arranged above the focal spot of the traditional compound parabolic concentrator to realize the reuse of the escaped light and improve the solar energy conversion efficiency of the device.The ray tracing of the novel compound parabolic concentrator based on photothermal photovoltaic coupling energy supply was carried out with optical software,and the influence of radial incident angle on the light receiving rate was compared and analyzed.In the actual environment,the variation of the inlet and outlet temperature,instantaneous heat collection and output power of the novel compound parabolic concentrator with time were tested and studied.The results indicate that the light receiving rate of the novel compound parabolic concentrator is consistent with that of the traditional compound parabolic concentrator.When the radial incident angle is 20 °,the light receiving rate of the novel compound parabolic concentrator is 89.00％,which is 72.82％higher than that of the traditional compound parabolic concentrator.In sunny days,the maximum outlet temperature,the photothermal conversion efficiency and the daily output power of the novel compound parabolic concentrator.are 34.20 ℃,73.40％and 118.40 W,respectively.关键词
