Abstract

The invention provides an anti-blue-light and high-transmittance coated front plate which comprises float glass, a first film structure is arranged on the float glass, the first film structure comprises a plurality of high-refractive-index film layers and at least one low-refractive-index film layer, a coating material used by the high-refractive-index film layers is Nb2O5, and a coating materialused by the low-refractive-index film layers is SiO2. The invention further provides an anti-blue-ray solar cell module which comprises the front plate, an adhesive film for packaging, a solar cell chip, a photovoltaic junction box and an aluminum alloy auxiliary frame, the front plate adopts the anti-blue-light and high-transmittance coated front plate, and the first film structure of the anti-blue-light and high-transmittance coated front plate is located at the position close to one side of the solar cell chip relative to the float glass. According to the anti-blue-ray solar cell module, the sunlight transmission rate reaches up to 90% or above in the whole sunlight spectrum range, and the prepared anti-blue-ray solar cell module is thick in color, free of chromatic aberration, capableof achieving multi-angle and large-angle observation and stable in color.

Description

technical field [0001] The invention relates to a front plate used in a solar cell module, in particular to a blue light-proof and high-transmittance coating front plate. [0002] The invention also relates to an anti-blue light solar cell assembly. Background technique [0003] Solar energy is a kind of clean energy. With the deepening of research on solar energy applications, building integrated photovoltaic (BIPV) technology is becoming more and more mature. The appearance of traditional solar cell modules presents a single black-gray color, and with the improvement of architectural aesthetics and personalized decoration requirements, the application of colored solar cell modules is gradually accepted and promoted by people, and colored glass or colored plastic substrates are widely used in characteristic Construction and other occasions. [0004] Among the existing colored solar cell components, blue solar cell components have a better matching degree with buildings an...
