Abstract: In view of the overall ray’s receiving rate of non-tracking CPC is obviously affected by incidence angle,this research designs a compound parabolic concentrating energy supplying device coupled photothermal and photovoltaic,which can receive the escaped light and achieve power output through adding double-sides photovoltaic modules at the entrance of CPC.Theoretical analysis of optical performance of the device utilizing optical simulation software TracePro,and the influence of incidence angle on the overall ray’s receiving rate of the device is contrastively studied.Based on the optical calculation results,a performance testing platform of compound parabolic concentrating energy supplying device coupled photothermal and photovoltaic is set up,and the influence of the receiver shape on the discrepancy between the inlet air temperature and outlet,the light-thermal conversion efficiency and the temperature in the cavity of device is first studied beneath the conditions of sunny weather,then analyze the variation rules of photovoltaic modules with operating conditions.The outcomes manifested that the incidence angle has little effect on the overall ray’ s receiving rate of the device compared with the traditional CPC,when α=12 o,the overall ray’ s receiving rate of device is 97.5%,which is 47.73% higher than CPC with the same size parameters.At air flow rate is 2.87 m/s,the maximum discrepancy between the inlet air temperature and outlet of device with（?）-shaped receiver is 14.6 ℃,which is 4 ℃ higher than that with mesh receiver at the same.Furthermore,the average light-thermal conversion efficiency of device with（?）-shaped receiver is 77.27%,correspondingly 61.28% for device with mesh receiver.Also,the results show that,if utilizing the（?）-shaped receiver,the maximum power output of the No.2 is 0.77 W and 45.28% higher than that of No.1 photovoltaic module.The technology has reference value for improving the comprehensive performance of non-tracking compound parabolic concentrating device.
