Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with specific embodiments, but it should be noted that these embodiments are not limitations of the present invention, and those of ordinary skill in the art can make functional, method, or structural equivalent transformations or replacements based on these embodiments. , all fall within the protection scope of the present invention.

[0028] The repair method of the flexible thin film solar cell of the present invention includes front repair or back repair, that is, the repair method of the present invention can independently repair the front or back of the flexible thin film solar cell.

[0029] Wherein, when the front side of the flexible thin film solar cell is damaged, it can be repaired by means of front side repair. Specifically, the front repair includes the following steps:

[0030] Lay the EVA layer on the front side of the solar cell, lay the ETFE layer on the EVA layer laid on the front...

Abstract

The invention provides a repair method for a flexible thin-film solar cell. The method comprises the steps of front-face repair or back-face repair; front-face repair comprises the following steps that an EVA layer is laid on the front face of the solar cell, an ETFE layer is laid on the EVA layer laid on the front face of the solar cell and connected with an electrode of the solar cell through a lead, the lead is led out, and lamination and cutting treatment are performed; back-face repair comprises the following steps that an EVA layer is laid on the back face of the solar cell, a back plate layer is laid under the EVA layer laid on the back face of the solar cell, and lamination and cutting treatment is performed. According to the method, the flexible thin-film solar cell with the poor appearance is repaired, recycling of the flexible thin-film solar cell is ensured, and the product rejection rate is lowered. The repaired flexible thin-film solar cell can keep the original appearance, and use of the flexible thin-film solar cell is not affected.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a method for repairing flexible thin-film solar cells. Background technique [0002] Flexible solar cell is a kind of thin film solar cell, which has the advantages of advanced technology, excellent performance, low cost and wide application. It can be applied to fields such as solar backpacks, solar convertibles, solar flashlights, solar cars, solar sailboats and even solar airplanes. [0003] However, the existing flexible solar cells cannot be repaired when problems such as scratches or punctures occur on the appearance, and can only be discarded, which causes waste of flexible solar cells. [0004] Therefore, in view of the above problems, it is necessary to propose a further solution. Contents of the invention [0005] The purpose of the present invention is to provide a method for repairing flexible thin-film solar cells, so as to overcome the deficiencies in the pr...
