Problems solved by technology

[0006] 1. Silicon wafers need to be loaded into the jig one by one before texturing, and need to be taken out one by one after texturing, which is difficult to automate and is not conducive to automatic connection with the processes before and after texturing
[0007] 2. The amount of liquid medicine used is large and the waste is serious
[0008] 3. The tank body is large, and the temperature uniformity of the liquid medicine is not easy to control, which affects the "pyramid" effect of the texture
[0009] 4. Restricted by the transfer capacity of the manipulator and the size of the tank, the production capacity is greatly limited

Embodiment Construction

[0032] The embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] Such as figure 2 The structure diagram of the leaf-type solar texturing device of the shown embodiment one specifically includes:

[0034] The feeding unit 201 senses the silicon wafer transferred from the previous process and sends it to the texturing unit 202;

[0035] The texturing unit 202 sprays liquid medicine for texturing according to the set pressure, and the pressure setting range of the silicon wafer delivered by the feeding unit 201 is 0-0.6Mpa;

[0036] The cleaning unit 203 is used to clean the silicon wafers after the texturing unit has been textured; it includes an etching pickling unit, an etching alkali washing unit, and a pure water rinsing unit to clean the silicon wafers passing through the texturing unit 202;

[0037] The drying unit 204 is used to dry the silicon wafers cleaned by the cleaning unit 203, and ...

Abstract

The invention discloses a leaf-type solar wool-making device. Silicon chips are arranged among a feeding unit, a wool-making unit, a cleaning unit, a drying unit and a discharging unit and are used as a transfer driving unit by a shaft vertical to the moving direction and a roller on the shaft; and spraying units are arranged above the wool-making unit and the cleaning unit for spraying liquid medicine. The invention also discloses a method of using the device to carry out wool making by the silicon chips, namely the wool making is finished on the silicon chips moved in a leaf manner through spraying the liquid medicine. The invention can save automatic connection of equipment of the procedure of loading and taking chips and the former and later procedures, improve the automation level, have a little consumption of liquid medicine and good effect of wool-making as 'pyramid', and improve the productivity by more than 30 percent.

Description

technical field [0001] The invention relates to the field of solar cell production equipment, in particular to a leaf-type solar texturing device and method. Background technique [0002] Non-renewable energy sources such as oil, natural gas, coal, etc. have gradually failed to meet people's needs. All countries in the world are vigorously developing new renewable energy sources. Due to its inexhaustible advantages, solar energy is currently developing rapidly. The proportion of scale is increasing. [0003] In order to improve market competitiveness, solar cell production faces the problem of high power generation costs, and it is necessary to increase production capacity and photoelectric conversion efficiency. In the texturing process of solar cell production, the texturing process is to roughen the smooth surface of the silicon wafer to increase the surface area for receiving sunlight and thus improve the photoelectric conversion efficiency. The "pyramid" effect on the...
