Screenless secondary printing method for positive electrode of crystalline silicon solar cell

The present invention discloses a screenless secondary printing method for a positive electrode of a crystalline silicon solar cell. The method comprises that: a silk-screen printing machine is used to perform two times of printing of DP1 and DP2, wherein the sub-grid line is printed in the DP1, the main grid line and the sub-gate are printed in the DP2, and the silk-screen printing plate used forDP1 and DP2 printing is a screenless silk-screen printing late; the sub-grid line and the positioning points are printed onto the cell sheet by using the slurry through the DP1 screenless silk-screenprinting plate; four solid positioning points on the cell sheet is captured by using the HD camera, and the cell sheet is automatically adjusted to the appropriate position to achieve precise contrast with the alignment point on the DP2 screenless silk-screen printing plate; and the main grid line and the sub-grid line are printed onto the cell sheet by using the slurry through the DP2 screenlesssilk-screen printing plate. According to the method disclosed by the present invention, the limitations of the traditional printing process is broken through, the aspect ratio of the sub-grid printing is improved, the printing quality of the grid line is improved, and the electrical performance and the excellent product rate of the cell sheet are improved.

The present invention discloses a method for preparing a PERC (Passivated Emitter and Rear Cell) screenless printing single crystal solar cell sheet. A single crystal silicon wafer is used as a base material, and the PERC screenless printing single crystal solar cell sheet is prepared by the sequential steps of texture surface making, diffusion, etching, back passivation, anti-reflection film plating, laser grooving on the back surface, back electrode, back electric field and positive electrode printing, sintering, and light failure reduction. The step of back passivation is to plate Al2O3 andSiNX on the back surface of the silicon wafer; the step of the anti-reflection film plating is to plate the SiNX on the front side of the silicon wafer; and the step of the back electrode, back electric field, and positive electrode printing is to use silk-screen printing, and the positive electrode printing plate uses a screenless printing plate. According to the method for preparing the PERC screenless printing single crystal solar cell sheet provided by the present invention, the LID of the cell sheet can be reduced to around 1%, the power of the component product is improved, conversion efficiency is high, and both the grade and electrical properties are significantly improved.

Discharging mechanism of energy-level molecular material cell tearing equipment and discharging method

The invention discloses a discharging mechanism of energy-level molecular material cell tearing equipment. The discharging mechanism is characterized by comprising a baffle, at least one material guide outlet penetrating through the baffle, and at least two negative feedback pressure adjusting holes formed in the periphery of the material guide outlet. During actual working, the baffle is arranged on an energy field cavity of the cell tearing equipment and serves as a side surface of the energy field cavity, and materials with large mass are thrown to the edge of the energy field cavity by centrifugal force under the action of centrifugal and centripetal forces in the energy field cavity; materials with small mass are collected to the center of the energy field cavity by the centripetal force under the action of a pressure difference, so that the materials are guided out and collected by the material guide outlet and screenless separation of the materials is realized. Particularly, when the materials are guided out, feedback air pressure is injected into the negative feedback pressure adjusting holes at the same time to effectively guarantee that the materials are guided out stably and uniformly.
