TY - JOUR TI - Experimental study on a high concentration photovoltaic/thermal system with plane mirrors array AU - Chen Haifei AU - Yang Jie AU - Ji Jie AU - Huang Wenzhu AU - Pei Gang AU - Zhang Yang JN - Thermal Science PY - 2018 VL - 22 IS - 12 SP - 517 EP - 525 PT - Article AB - A high concentration photovoltaic/thermal system based on plane mirrors array has been developed and analyzed. It is found that the system with plane mirrors array not only can reduce the cost but also achieve a uniform illumination and adjustable concentration ratios. The system produces both electrical and thermal energy, with the electrical efficiency above 22% and the thermal efficiency above 47%. The experimental results show that the temperature coefficient of open circuit voltage in this photovoltaic module is around –0.12 V/°C. Moreover, when the concentration ratio varies between 200 and 450, the decrease of electrical efficiency with the temperature is 0.08% per°C.
