Problems solved by technology
[0003] In the prior art, the internal resistance of the interconnection structure of laminated solar cells is too large, which affects the overall power output, and due to the limitation of the transmission resistance of the interconnection structure itself, a smaller transmission distance is required between solar cells. Therefore, it is necessary Cutting the whole solar cell into smaller solar cells will reduce the yield and increase the risk of solar cell cracks

Abstract
The invention discloses a double-sided solar cell interconnection structure. Thestructurecomprises at least two solar cells, wherein the adjacent solar cells are electrically connected through a connecting assembly, and the connecting assembly comprisesconductors. The conductorsareelectrically connected with a front electrode grid line of one solar cell, and the conductorare electrically connectedwith the electrode grid line on the back surface of the other solar cell; the conductorsare radially arranged from one side, close to the other solar cell, of any solar cell to one side, far away from the other solar cell, of the solarcell; the front electrode grid lines and the back electrode grid lines are connected through the conductors, so two adjacent solar cells are connected, the closer the conductorsare to the position between the two solar cells, the smaller the distance between the conductorsis, the length of the conductorscan be reduced, resistance can be reduced, the transmissiondistance can be reduced, and the solar cells with large sizes can be used for lamination.
Description
Technical field [0001] The present invention generally relates to the field of photovoltaic power generation, in particular to the field of solar cells, and in particular to a double-sided solar cell interconnection structure. Background technique [0002] At present, with the gradual exhaustion of fossil energy, solar cells are used more and more widely as a new energy alternative. Solar cells are devices that convert the light energy of the sun into electrical energy. The solar cell uses the photovoltaic principle to generate carriers, and then uses electrodes to draw the carriers out, which facilitates the effective use of electric energy. Solar cell interconnection is an important part of photovoltaic solar power generation, and its technical solutions have an important impact on the performance of photovoltaic power generation. The laminated battery interconnection technology is a better solution for realizing efficient battery interconnection. In the laminated interconne...
