Abstract

High temperature can result in the degradation of any device (solar, electrical, electronics, etc.). For example, in the case of a silicon photovoltaic (PV) system, approximately 25% of the incoming concentrated solar energy will be converted into electrical energy and the remaining is converted into waste heat which contributes to elevate the cell temperature and so decreases its efficiency. The main objective of this project is to emphasize the Phase Change Material (PCM) cooling technique. This kind of material is known for its high storing capacity of the temperature which will enhance the cycle lifetime of any device. In this project, a direct application on a PV panel was carried out, an organic PCM is tested in order to study its properties and capacity of absorption. The results shows that around 13% of the energy can be saved. Another objective of this project consists of a numerical validation of the modeling used to determine the temperature of a photovoltaic panel. This validation allows us to use this model in order to decide on the efficiency of any PCM to be used.

使用相变材料冷却光伏组件

高温会导致任何设备(太阳能、电气、电子等)的退化。例如，在硅光伏(PV)系统的情况下，大约25%的入射集中太阳能将转化为电能，其余的将转化为废热，这有助于提高电池温度，从而降低其效率。本项目的主要目的是强调相变材料(PCM)冷却技术。这种材料以其高温度存储能力而闻名，这将提高任何设备的循环寿命。在这个项目中，进行了直接应用在光伏电池板上，测试了有机PCM，以研究其性能和吸收能力。结果表明，可节省约13%的能源。该项目的另一个目标是对用于确定光伏板温度的模型进行数值验证。这个验证允许我们使用这个模型来决定要使用的任何PCM的效率。
