Study on thermal performance of phase change materials in photovoltaic system

The thermal performance of solar cells plays an important role in the energy use photovoltaic power generation. surface temperature is a key factor affecting generation efficiency. phase change materials can increase storage capacity and weaken fluctuation under action radiation, achieving purpose improving system performance. aim this paper to investigate their for cell modules through simulations experiments. In experimental study, six types binary composite were prepared by selecting two lauric acid, stearic palmitic acid tetradecanol 1:1 ratio. tests materials, latent heat measured thermogravimetric method using TGA/DSC simultaneous analyser, conductivity was probe meter. simulation numerical model transfer developed, coupling material components performing analysis. results are helpful selection that beneficial reducing panels explore effect radiation levels on materials.
