Abstract

The invention relates to a diffusion source coating device. The diffusion source coating device is used for coating a sample and comprises a rotary mechanism, a fixed frame, a support and a nozzle array, wherein the rotary mechanism is connected with the fixed frame; the support is connected with the rotary mechanism; the nozzle array is connected with the support and comprises a plurality of nozzles arranged on the support. When the diffusion source coating device is used for coating the sample, the rotary mechanism drives the support to rotate to enable the nozzles on the support to rotationally perform diffusion source coating on the sample. According to the diffusion source coating device, the coating effect and the processing efficiency can be improved, diffusion source materials are saved and the process cost is lowered.

Description

technical field [0001] The invention relates to the field of coating equipment, in particular to a diffusion source coating device. Background technique [0002] The diffusion process and the coating source technology of the diffusion source have been widely used in the fields of microelectronics and photovoltaics. Diffusion sources can be divided into gaseous sources, solid sources and liquid sources. Among them, liquid diffusion sources have the advantages of simple process, convenient equipment operation and low operating risk factor. In addition, applying the coating source technology of liquid diffusion sources to high-efficiency solar cells can significantly reduce equipment hardware requirements while meeting process technical requirements, thereby reducing equipment costs and subsequent maintenance costs. [0003] Generally, the commonly used coating technology of liquid diffusion source is spin coating or spray coating process, which mainly adopts the coating metho...
