Production process for photovoltaic cell assembly

Abstract

The invention discloses a production process for a photovoltaic cell assembly. The production process is characterized by comprising the following steps of: testing a single bracket; welding the anode and cathode of a photovoltaic cell chip; overlapping; detecting a photovoltaic cell assembly; and laminating, curing and framing. In the production process, framing is performed along the top angle lines of the four corners of a frame, so that the framing time of a single piece is shortened, the connection is firm, the verticality of the periphery of the frame is high, great convenience is brought to the splicing of a photovoltaic cell matrix, and the working efficiency is increased by 70 percent. In a laminating process, bubbles are not generated in the melting process of EVA (Ethylene Vinyl Acetate), so that the quality of the photovoltaic cell assembly is improved, the efficiency of conversion of solar energy to electric energy is effectively ensured, and the service life of the photovoltaic cell assembly is prolonged.

Description

technical field [0001] The invention relates to a production process of photovoltaic battery components, which relates to the technical field of photovoltaic battery power generation and is applied to photovoltaic power generation. Background technique [0002] At present, the production process of domestic photovoltaic cell components includes single-chip classification testing, welding of positive and negative electrodes of photovoltaic cells, stacking, lamination curing, and framing processes. During the whole process, the photovoltaic cells are graded according to the electrical performance, and the photovoltaic cells with similar performance are combined by welding to form the photovoltaic cell group with the highest efficiency. In order to ensure the service life of the photovoltaic cell group, TPT is generally used. -EVA-photovoltaic battery pack-EVA-tempered glass laminated structure is sent to the laminator for lamination, and the EVA is melted, so that the photovol...

AI Technical Summary

Problems solved by technology

Due to the unreasonable configuration of the entire process, as long as one piece of the photovoltaic cell assembly is damaged, the photovoltaic cell assembly cannot be used normally; Unreliable, which reduces the conversion efficiency of photovoltaic cells, and is prone to aging, corrosion, shortened service life and other defects, wasting a lot of energy and investment funds

In addition, when framing, the corner connectors on the side of the hollow frame strips are drilled and screwed with self-tapping screws to fix the frame, resulting in unreliable connections, low assembly efficiency, and poor verticality around the frame, which is difficult for assembly.
