Abstract

The invention relates to a photovoltaic laminating piece. The photovoltaic laminating piece comprises a transparent cover plate, a first sealing layer, a battery piece layer, a second sealing layer and a back plate which are laminated in sequence, wherein the battery piece layer comprises a plurality of connected battery pieces and a converge belt electrically connected onto the battery pieces; an electrode exposing hole is formed in the back plate, and the electrode exposing hole passes through the back plate and the second sealing layer so that the converge belt is leaked out. According to the photovoltaic laminating piece, the hidden cracking problem of the battery pieces caused by improper outgoing line penetration is avoided; and the manual workload can be greatly reduced. Moreover, the electrical connection quality of the photovoltaic laminating piece and a junction box is improved, the workload of subsequent cleaning stations is reduced, and the cleaning frequency and workload of a laminating machine are reduced. The invention also provides a preparation method of the photovoltaic laminating piece and a photovoltaic module comprising the photovoltaic laminating piece.

Description

technical field [0001] The invention relates to the technical field of photovoltaic cells, in particular to a photovoltaic laminate, a preparation method thereof, and a photovoltaic module. Background technique [0002] At present, the production process of photovoltaic laminates is generally to open holes in the predetermined positions of the back sheet and the upper EVA, and then stack the transparent cover, the lower EVA, the battery sheet, the upper EVA, and the back sheet. Pass the bus strip connected to the battery sheet through the upper EVA and the opening on the back panel so that the bus strip extends out of the back panel, that is, the action of leading out the line in the stack; after that, laminate the stacked components to form photovoltaic laminates. [0003] However, it is easy for the operator to cause cracks in the battery sheet due to careless operation when the operator is threading out the wires; improper threading out of the wires is one of the most im...
