Abstract

The invention relates to the technical field of the solar battery, and specifically is a wafer manufacturing device of the solar battery. The device comprises an upper mounting plate, an electric actuator, a first motor, a pressure device, a mould, a mould rack, a lifting component, a driver and a heater; the end of a cylinder rod of the electric actuator is fixedly connected with a non-output endof the first motor; the end of a rotating shaft of the first motor is fixedly connected with the pressure device; the end of the rotating shaft of the first motor is fixedly connected with the top ofthe middle part of a first bracket; a pressure roller is rotationally installed under the first bracket; and the pressure roller is driven by the electric actuator that is driven by the motor. By adoption of the wafer manufacturing device, the material is not stacked when the wafer is rolled, so as to ensure the uniform density of the rolled wafer; a retractable plate is set on the periphery of the side wall of the mould cavity, so that the melted wafer can be continuously rolled after the wafer is lifted by the lifting component; and thus, the processing efficiency of the wafer is improved.

Description

technical field

[0001] The invention belongs to the technical field of solar cell manufacturing, in particular to a solar cell wafer manufacturing device. Background technique

[0002] Wafer refers to the silicon chip used in the production of silicon semiconductor integrated circuits. Wafer is the carrier used in the production of integrated circuits. In general, wafers refer to single crystal silicon wafers. Wafer is the most commonly used semiconductor material. According to its diameter, it is divided into 4 inches, 5 inches, 6 inches, 8 inches and other specifications. Recently, 12 inches or even larger specifications have been developed. The larger the wafer, the more ICs that can be produced on the same wafer, which can reduce costs; but the requirements for material technology and production technology are higher, such as uniformity and so on. It is generally believed that the larger the diameter of the silicon wafer, it means that the fab has better technology. In ...
