With the structure of photovoltaic/phase change material(PV/PCM) thermal control system as the research object,the mechanism of photoelectric thermal conversion,transmission,storage and temperature control is studied,and the two-dimensional finite element thermal control analysis model of PV/PCM is established.The effects of thermal conductivity,melting point,thickness and irradiance of phase change materials on the internal temperature distribution of PV/PCM and the temperature control characteristics of solar cells were studied.Three PV/PCM experimental prototypes with peak melting points of 42.9 ℃,46.7 ℃ and58.1 ℃ were designed and tested under simulated light source conditions.The time for controlling the temperature of the three prototype solar cells is within 50 ℃ is 1.6 h,1.45 h and 1.18 h respectively,and the average output power increases by 8.76%,6.95% and 3.9% respectively compared with that of solar cells without PCM thermal control.The research results provide theoretical and experimental reference for the optimal design of PV/PCM system.
