Problems solved by technology

[0004] After lamination, since the glass, EVA, battery, EVA, and backplane will be tightly bonded together, it is difficult to separate, resulting in difficulty in repairing
Therefore, it is difficult to repair, the speed of repair is slow, and the success rate of repair is low.

Embodiment Construction

[0018] After a conventional photovoltaic module is laminated, when there are defects such as single cracks, it needs to be repaired. This patent is to design and invent a single-piece repair method for conventional photovoltaic modules after lamination.

[0019] The main tools involved in this method include utility knife, needle-nose pliers, hot air gun, frosted eraser, tweezers, electric soldering iron, steel ruler, and scalpel, all of which are purchased directly on the market, so no further explanation is needed. Those skilled in the art should be able to master the tools used for repairing battery cells.

[0020] A method for repairing a single piece of a module after lamination. After the photovoltaic module is laminated, when a defective single piece is found to be repaired, the single piece is repaired according to the following steps

[0021] Step 1. Knock down the aluminum frame with a mallet and a wooden drill to become a frameless component, that is, only a "lamin...

Abstract

The invention relates to the field of solar cell production. The method for repairing a laminated assembly single piece comprises the following steps that after a photovoltaic module is laminated, single piece repairing is carried out when a defective single piece is found; an aluminum frame is knocked down by using a wooden stick and a wooden drill to form a frameless component, namely, only a "laminated part"; an EL test is carried out, and by combining circulation single information, the position of the defective single piece is determined; a back plate is removed, and lines are marked along the periphery of the defective region by using an art knife, wherein the marking positions are the same as the positions of nearby back electrodes of the surrounding four battery pieces. The invention provides a universal, reasonable, procedure and detailed operation method aiming at the current situation that a laminated assembly is difficult to repair and slow in repair, so that the repair difficulty of the component after lamination is reduced, the repair speed is increased, the repair success rate is improved, and a direction is provided for repairing poor components.

Description

technical field [0001] The invention relates to the field of solar cell production, in particular to a method for repairing photovoltaic components. Background technique [0002] In the production process of photovoltaic modules, after lamination, the glass, EVA, battery, EVA, and backsheet will be tightly bonded together, making it difficult to separate. Therefore, at the front EL test site, defects such as hidden cracks, low efficiency, and black spots on the cells will be carefully inspected and repaired to avoid defects that flow to the lamination and cause difficulties in repairing. [0003] However, due to the influence of various factors such as temperature, pressure, material, assembly line flatness, external force, and man-made, it is inevitable that there will still be defects such as cell cracks, ribbon offset, and even hair strands and paper scraps after lamination. phenomenon, including finished components. Among them, cell cracks are the main ones. [0004] ...
