Problems solved by technology
[0005] The technical problem to be solved by the present invention is: in order to solve the technical problem that large hook marks are easily produced on the edge of the silicon wafer in the prior art, and the silicon wafer retaining arm at the bottom of the retainer is easily deformed after being cleaned by a wire brush. The present invention provides a Solar cell coating machine graphite cabinet
The existing U-shaped hook is improved into a clamping type, and there is no contact point with the bottom of the silicon wafer, which solves the technical problem of the hook mark left by the silicon wafer coating and improves the conversion efficiency of the cell

The invention relates to the technical field of solar cell slice coating, in particular to a graphite cabinet of a solar cell slice coating machine. The graphite cabinet comprises a graphite bearing frame, wherein the graphite bearing frame comprises graphite frame ribs arranged in a staggered way, and hooks and baffle supports are arranged on the graphite bearing frame. In the graphite cabinet of the solar cell slice coating machine, disclosed by the invention, with improvement on a hook structure at the bottom of the hook, no contact point is arranged between the hook and the bottom of a silicon wafer, the technical problem of hook mark remaining on a coating film is solved, and the conversion efficiency of a cell slice is improved; with the camber surface design at the bottom, a silicon wafer baffle arm is difficult to deform during silicon wafer cleaning; and moreover, a dead angle is more convenient to clean, and the coating quality is improved.
Description
technical field [0001] The invention relates to the technical field of solar battery sheet coating, in particular to a graphite cabinet for a solar battery sheet coating machine. Background technique [0002] Using solar cells to generate electricity is one of the important ways to solve energy and environmental problems. At present, more than 80% of solar cells are made of crystalline silicon materials, and the preparation of high-efficiency and low-cost crystalline silicon solar cells is of great significance for large-scale utilization of solar power generation. The preparation of anti-reflection film and hydrogen passivation are one of the very important procedures for preparing high-efficiency crystalline silicon solar cells. [0003] PECVD coating is divided into tubular PECVD coating and flat PECVD coating. The cost of the latter is slightly lower, and it is generally used more. Flat-type PECVD coating must use a frame-type silicon chip carrier, that is, a graphite ...
