Abstract

The invention discloses a photovoltaic backboard and a manufacturing method thereof. The photovoltaic backboard comprises a metal substrate, a water absorbing layer, a first weather-proof layer, a second weather-proof layer, a polymer base film layer, an insulating layer and a water blocking layer, wherein the metal substrate, the water absorbing layer, the first weather-proof layer, the second weather-proof layer, the polymer base film layer, the insulating layer and the waterproof layer are sequentially arranged, a plurality of through holes are formed in the metal substrate, the cooling performance of the backboard is excellent, and the preparation method is simple.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic backplanes, and relates to a photovoltaic backplane and a manufacturing method thereof. Background technique [0002] Solar photovoltaic power generation is the most important type of renewable energy. Countries all over the world are scrambling to develop solar photovoltaic power generation, and to formulate and implement the road map of photovoltaic power generation. In the past five years, the global solar photovoltaic industry has grown at a rate of more than 50%, and it is predicted that it will continue to develop at a rate of more than 30% in the next ten years. [0003] The solar back sheet is located on the back of the solar panel, which protects and supports the cells, and has reliable insulation, water resistance and aging resistance. [0004] With the continuous irradiation of sunlight, the photovoltaic backplane will continue to heat up, resulting in a decrease in the photovolt...
