Abstract

The invention relates to a solar battery assembly. The solar battery assembly comprises at least two battery packs connected in series. Each battery pack comprises at least two battery piece string columns which are connected in parallel. Each battery piece string column comprises at least two battery cutting pieces which are connected in series, and every two adjacent battery cutting pieces are connected in series in an overlapping mode. The solar battery assembly further comprise elastic dummy wafers located in the battery packs and connected with the at least two battery piece string columns, and the at least two battery piece string columns are made to form two parallel-connection structures connected in series. In the solar battery assembly, the elastic dummy wafers can provide certain elasticity, the overall elasticity of the solar battery assembly is improved, essential elastic deformation is achieved to resist the outer or inner stress deformation requirement, the risk that cracks of the solar battery assembly are hidden is reduced, and the solar battery assembly is not prone to gate breakage and crack. Circuits can be connected between the battery piece string columns in the same battery pack, current can be shunt when local shielding happens, and power influences of the whole string in the early stage are reduced.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a solar cell component and a preparation method thereof. Background technique [0002] As a new energy source, solar energy has the advantages of being inexhaustible, clean and environmentally friendly compared with traditional fossil fuels. At present, the main solar energy utilization method is to convert the received light energy into electrical energy output through solar cell components. The traditional solar cell component is formed by connecting several solar cells (or photovoltaic cells) in series and then packaging them in a square array. large-area battery components. Among them, the solar cell sheet absorbs light energy, and the accumulation of charges of opposite signs occurs at both ends of the battery, which generates "photovoltaic voltage", which is the "photovoltaic effect". Under the action of the photovoltaic effect, the two ends of the solar cell generate ...
