Abstract

The invention provides a fluid infusion apparatus and a wet etching system of a solar cell chip containing the fluid infusion apparatus and belongs to the technical field of solar cell. The fluid infusion apparatus comprises: a fluid infusion container, a liquid level pipe, a liquid level inductor arranged on the liquid level pipe, a hand-operated liquid feeding pipe which communicates with the liquid level pipe, a first valve, a second valve and a flowneter which are disposed on the hand-operated liquid feeding pipe, and an automatic liquid feeding pipe. The wet etching system comprises the fluid infusion apparatus which is used to quantitatively supplement a corresponding liquid medicine into a reaction tank. By controlling the first and second valves, the fluid infusion apparatus can operate in three modes. The liquid level inductor is simple and convenient for calibration. The liquid medicine is largely supplemented into the reaction tank in a nonautomatic mode, and it is not necessary to stop the operation of the wet etching system. The process is convenient, simple and highly efficient.

Description

technical field [0001] The invention belongs to the technical field of solar cells, in particular to a wet etching system for solar cells, and in particular to a liquid replenishing device for the wet etching system. Background technique [0002] Due to the limited supply of conventional energy and the increase in environmental protection pressure, many countries in the world have set off an upsurge in the development and utilization of solar energy and renewable energy, and solar energy utilization technology has developed rapidly. The use of electric energy is becoming more and more extensive. The solar cell is one of the most commonly used devices to convert solar energy into electrical energy. [0003] A solar cell is made by a solar cell (such as a monocrystalline silicon solar cell) through a wet etching process and other steps, for example, a wet etching process such as a texturing process and an etching and edge removal process. In order to ensure the yield of sola...
