Abstract: 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 ℃ and 58.1 ℃ 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.
