Abstract

The invention discloses a cleaning method of cadmium telluride thin film solar cell conductive glass, which can effectively clean pollutants on glass surface, so as to meet the production requirements of solar cells; the cleaning method comprises the following steps: (1) high purity water is used for preparing sodium hydroxide solution with 0.1-20 percent of concentration; (2) the conductive glass to be cleaned is soaked in the prepared sodium hydroxide solution for 5-20 minutes at room temperature; (3) the surface of the conductive glass is repeatedly cleaned by a roller brush for 1-5 minutes; (4) the high purity water is used for preparing hydrofluoric acid solution with 0.1-20 percent of concentration; (5) the brushed conductive glass is soaked in the prepared hydrofluoric acid solution for 1-10 minutes at room temperature; (6) the conductive glass is taken out from the hydrofluoric acid solution and is rinsed by deionized water at room temperature; (7) the conductive glass is taken out from the deionized water and is dehydrated by placing in absolute alcohol.

Description

technical field [0001] The invention relates to a method for cleaning conductive glass of a cadmium telluride thin film solar cell. Background technique [0002] With the rapid development of the solar cell industry, thin-film solar cell production technology and equipment are becoming more and more popular. Some professional cleaning equipment manufacturers have invested a lot of design and development in this area to develop thin-film solar cell production equipment required by the design industry. The current technical scheme is: feeding + wind cutting → lotion spray washing → wind cutting → rolling brush washing 1 → rolling brush washing 2 → spray washing 1 → spray washing 2 → DI water washing → air knife drying → film removal. Due to the particularity of the production of cadmium telluride thin-film solar cells, the cleanliness of the conductive glass is required to be clean to the monomolecular layer. The above-mentioned ordinary cleaning methods cannot meet the requi...
