研究目的
Investigating the influence of phase change material (PCM) characteristics on the thermal control of solar cells to improve photovoltaic power generation efficiency.
研究成果
PCM thermophysical properties significantly influence solar cell thermal control characteristics. Optimal phase change temperature, thermal conductivity, and latent heat value can enhance thermal control, but performance is affected by environmental conditions. The findings aid in the optimization of PV/PCM solar cell thermal control systems.
研究不足
The study is limited by the specific phase change materials and environmental conditions tested. Further research is needed to explore a wider range of materials and conditions.
1：Experimental Design and Method Selection:
A two-dimensional thermal control structure model of PV/PCM solar cell thermal control system was established to study the influence of PCM phase change temperature, thermal conductivity, and latent heat value on solar cell temperature control characteristics.
2：Sample Selection and Data Sources:
The study used lauric acid-stearic acid composite phase change material as a reference, with parameters before and after phase change detailed in tables.
3：List of Experimental Equipment and Materials:
Solar cells, phase change materials, package casings (aluminum boxes), and thermal silica gel between the solar cells and the package casing were used.
4：Experimental Procedures and Operational Workflow:
The study analyzed the thermal control effect under different environmental conditions (solar irradiance, ambient temperature).
5：Data Analysis Methods:
The influence of PCM thermophysical parameters on thermal control characteristics was analyzed through graphical representation of results.
