Abstract

The invention discloses a texturing component of a thin-film solar glass substrate texturing unit and solves the problem that an existing texturing unit is low in automation level and nonuniform in texturing thickness. The texturing component of the thin-film solar glass substrate texturing unit comprises a PLC (programmable logic controller) and a rectangular bottom tank (1). A raised etching tank (2) is nested into the rectangular bottom tank (1). A water homogenizing plate (12) is disposed on a frame (11) and is provided with evenly distributed holes. A bottom plate of the etching tank is provided with a bottom etchant inlet which is communicated with one end of a lower etchant feeding pipe (9). The other end of the lower etchant feeding pipe (9) is communicated with a master feeding pipe (10). A charging roll (7), roller sets (13) and a discharging roll (8), which are used for conveying thin-film glass substrates, are sequentially disposed from left to right above the water homogenizing plate (12). Etchant spray pipes are disposed above the roller sets (13). Dynamic drain pipes (27) are disposed at the bottom of the rectangular bottom tank (1). By the texturing component, automatic production is achieved, and etching quality is improved.

Description

technical field [0001] The invention relates to a texturing device for a thin-film solar glass substrate, in particular to a texturing part in the texturing device for a thin-film solar glass substrate. Background technique [0002] At present, the utilization of renewable energy has become a new trend of future energy development. Compared with other renewable energy sources, photovoltaic energy has great potential and has developed rapidly in recent years. Thin-film battery, as the basic component of photovoltaic energy, is constantly increasing in the field of photovoltaic cells due to the low consumption of raw materials and low substrate cost. As the key equipment in the thin film battery manufacturing industry, glass substrate texturing equipment completes the texturing process of preparing ZnO thin films on glass substrates, and is the main equipment to improve the photoelectric conversion efficiency of batteries. The existing texturing equipment for the surface of ...
