Cooling sheet for photovoltaic modules, method of manufacturing the same and photovoltaic modules including the same

摘要

A cooling sheet for photovoltaic modules, a method of manufacturing the same, a backsheet for photovoltaic modules, a method of manufacturing the same, and a photovoltaic module are provided. The cooling sheet for photovoltaic modules which includes a resin layer can be prepared by coating or impregnating one surface of a porous substrate with a super-absorbent polymer (SAP) containing a fluid. Here, the resin layer includes the fluid-containing SAP which is formed on one surface of the porous substrate or impregnated with the porous substrate. When the cooling sheet for photovoltaic modules is attached to the outside of the weather-resistant substrate to prepare the backsheet for photovoltaic modules, it is possible to suppress an increase in power generation temperature of a photoelectric cell by evaporation of the fluid, for example water, included in the SAP, thereby improving the power generation efficiency of the photovoltaic module.
