METHOD FOR MANUFACTURING THIN-FILM SOLAR CELL SEMI-FINISHED PRODUCT

摘要

Provided is a method for manufacturing a thin-film solar cell semi-finished product, the method comprising the following steps: providing a transparent substrate having a front contact layer or a front contact layer sequence; and conducting flame scarfing on the front contact layer or the front contact layer sequence, the flame scarfing being conducted via one or more gas burners, and the surface temperature of the front contact layer being always maintained lower than the softening temperature of the front contact layer or the front contact layer sequence and the substrate. Provided is a method for cleaning the surface of a glass substrate coated with TCO. As a supplement to a traditional cleaning process, the method is easy to be integrated with well-known manufacturing processes and ensures a stable cleaning effect.
