Production process of full-black solar photovoltaic module

Abstract

The invention discloses a production process of a full-black solar photovoltaic module. The production process comprises the following steps: S1, coating of a battery piece; S2, battery piece welding;S3, stacking; S4, stacking inspection; S5, laminating; S6, lamination inspection; S7, frame assembling; S8, installing of a junction box; S9, curing of the assembly; S10, cleaning of the assembly; S11, component testing; S12, inspecting of the appearance of a finished product; S13, packaging and warehousing. In the production process of the all-black solar photovoltaic module: 1, a vapor deposition method coating process is adopted for a battery piece, silicon nitride coating is carried out on the battery piece, the thickness of a silicon nitride film is 20-75 nm or 120-300 nm, and finally the color requirement of the battery piece of the all-black module is met; 2, a black frame is adopted; 3, the black film strip is disposed on the surface of the interconnecting strip solder strip; 4, the black shielding strips are covered on the head and tail bus bars by adhesive tapes, so the battery pieces can be black at any angle after being packaged into an assembly.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to a production process for all black solar photovoltaic components. Background technique [0002] Photovoltaic modules are the key components of distributed photovoltaic systems, which undertake the important task of converting light energy into electrical energy. Photovoltaic modules are packaged in series by single cells, and high voltage can be obtained through series modules. get high current. [0003] In the market, in the production process of cell coating in photovoltaic modules, silicon nitride coating is used. The gas introduced in the process of silicon nitride coating is silane and ammonia, and the thickness of silicon nitride is 73-100nm In between, the photovoltaic modules finally appear blue, which leads to glare pollution in the process of using the photovoltaic system, and for some special building designs, such as black architectural style design, blue photo...

Problems solved by technology

[0003] In the market, silicon nitride coating is used in the production process of cell coating in photovoltaic modules. The gas introduced in the process of silicon nitride coating is silane and ammonia, and the thickness of silicon nitride is 73-100nm. In between, the photovoltaic modules finally appear blue, which leads to glare pollution in the process of using the photovoltaic system, and for some special building designs, such as black architectural style design, blue photovoltaic modules cannot be applied , while on the market, some black photovoltaic modules are only dark blue, and cannot achieve a completely black effect, so further research and improvement is needed in the field of completely black photovoltaic modules
