Solar module set

Abstract

The present invention provides a solar module set. The solar module set comprises a back plate, a first encapsulation layer, a plurality of solar cells, a plurality of welding tapes, a second encapsulation layer and light transmitting glass; the solar module set further comprises an optical film and temperature-sensitive color-changing particles; the optical film is arranged on the light transmitting glass and is located at the light entering surface of the light transmitting glass; the temperature-sensitive color-changing particles are arranged in the optical film; and when the temperature-sensitive color-changing particles are heated, and the temperature of the temperature-sensitive color-changing particles reaches a preset temperature range, the temperature-sensitive color-changing particles are converted from a transparent state to a first non-transparent color. The temperature-sensitive color-changing particles are arranged in the optical film on the light entering surface of the transparent glass, the temperature-sensitive color-changing particles can be changed from the transparent state to the first non-transparent color when stimulated by abnormal heating temperature, so that a user can judge whether an overheated region exists in the solar module set by means of the color change of the optical film, and incident light can be isolated through color change, and therefore, the solar cells can be forced to stop working, and further heat emission of the overheated region can be stopped or decreased, and fires or other safety problems can be avoided.

Description

technical field [0001] The invention relates to a photoelectric conversion device, in particular to a solar module. Background technique [0002] As a clean, economical and stable green energy, solar energy has been widely developed and utilized at present, and the most common application is a solar cell module, which converts light energy into electrical energy as a photoelectric conversion element. [0003] figure 1 is a schematic cross-sectional view of an existing solar module, figure 2 It is a top view of an existing solar module. [0004] Such as figure 1 and figure 2 As shown, the solar module 10 includes a backplane 11, a first encapsulation layer 12, a plurality of solar cells 13, a plurality of solder ribbons 14, a second encapsulation layer 15 and a light-transmitting glass 16, wherein the plurality of solder ribbons 14 are connected to multiple A plurality of solar cell strings 13 form a plurality of solar cell strings 13A, and the plurality of solar cell ...

Problems solved by technology

[0007] Since the solar module 10 needs to rely on a plurality of solar cells 13 connected in series with a plurality of ribbons 14 to generate the expected electric energy, however, due to the nature of the solar cells 13 itself, for example, when the solar cells 13 are silicon crystalline solar cells When the silicon wafer is in the wafer itself, the crystallization form of the silicon wafer and the welding stability between the solar cell 13 and the welding ribbon 14 will cause the impedance of some areas of the solar module 10 to increase, and cause the solar module 10 to easily overheat in a local area when it is working. phenomenon, in some extreme cases, the aforementioned overheating will even destroy the entire solar module 10
