Abstract

The invention discloses a composite back panel of a solar cell and a preparation process of the composite back panel. The preparation process includes acquiring a second substrate layer, wherein the second substrate layer comprises opposite first and second surfaces; plating the first surface of the second substrate layer with a plating layer to form a reflective layer; coating the surface, away from the second substrate layer, of the reflective layer with a first coating layer to form a silica gel layer; coating the second surface of the second substrate layer with a second coating layer to form a radiation layer. By the preparation process, the technical problem that conventional solar composite back panel materials are heavy is solved.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a solar cell composite back sheet and a preparation process thereof. Background technique [0002] With the widespread application and popularization of solar cell power generation technology with the advantages of environmental protection and energy saving, the huge market demand for back sheet film for solar cells has been driven. The solar cell backsheet is located on the back of the solar cell module, which protects and supports the cells and is one of the most important packaging materials to prolong the service life of the cells. [0003] The solar cell backsheet is an extremely important packaging material in photovoltaic modules, which supports and protects the cells. At the same time, it is in direct contact with the external environment on a large area and undertakes the important mission of ensuring stable power generation of photovoltaic modules. It must have exce...
