Abstract

The invention discloses a high-efficiency solar silicon panel and a preparation method thereof, and a battery module. The panel comprises cell sheets, a tempered white glass plate, an EVA adhesive film, a back plate, a wiring box and a section bar aluminum frame. Each cell sheet comprises a silicon sheet and silver grid lines and electrodes arranged on the front surface of the silicon sheet. The electrodes are in Z shape and are arranged vertical to the silver grid lines. The adjacent cell sheets are connected in series and parallel by lead wires and connected to the wiring box. The tempered white glass plate and the back plate are arranged above and under the cell sheets respectively. The EVA adhesive film is arranged between the tempered white glass plate and the back plate and between the back plate and the cell sheets. The section bar aluminum frame is arranged on the periphery of the cell sheets. A plurality of light focusing convex surfaces corresponding to the cell sheet respectively are arranged on the lower surface of the tempered white glass plate. The panel has high-efficiency light focusing power generating performance and is especially suitable for street lamp power supply. Through secondary overprint technology, the use amount of silver paste is reduced, so that the cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of solar cells, in particular to the production technology of battery sheets and battery components. Background technique [0002] Solar cells can directly convert light energy into electrical energy, and are receiving more and more attention. Currently, the main component of the electrode material of the solar cell, the main grid and the sub grid, is silver, and the cost of silver accounts for about 15% of the total cost of the solar cell, which is huge and expensive. To reduce the manufacturing cost of solar cells, it is very important to reduce the amount of silver paste used without negatively affecting the electrical performance. Contents of the invention [0003] Purpose of the invention: In view of the existing problems and deficiencies mentioned above, the purpose of the present invention is to provide a high-efficiency solar silicon battery panel and its preparation method, and battery components...
