Abstract： To address the issue of photovoltaic conversion efficiency degradation in solar cells under high-temperature condition， a new eutectic phase change energy storage material composed of C 16H 34O-C 16H 32O 2 and expanded graphite composite was developed. The eutectic phase change energy storage material was prepared by the melting method， and the solar cell device was designed using this material. The experimental results show that the latent heat of the eutectic phase change energy storage material reaches 182.3 kJ/kg， with an optimal phase transition temperature of 43.2 ℃， which can effectively mitigate the temperature fluctuations. The solar panel made with this material has an average voltage output increase of 0.42 V， an average power output improvement of 3%， and a high photoelectric conversion efficiency of 22.5%. This solar panel outperforms traditional silicon-based panels and demonstrates excellent aging resistance and environmental adaptability. These findings suggest that using this material for thermal management of solar panels can significantly increase the operational dependability and power production efficiency of the panels， offering a new approach to effective thermal management of the solar panels.
