Method for etching a see-through thin film solar module

摘要

This invention discloses a method for etching a see-through thin film solar module, comprising: printing ink paste which resists the etching of etching solutions in the protected area of the thin film solar module which is placed under a screen; drying and solidifying the ink paste; coating etching solutions on the thin film solar module; and removing the ink paste. The method of this invention can accurately position the see-through area, achieve various selections of see-through patterns, facilitate the realization of the see-through function in large-area thin film solar modules, and alleviate the problem that a short circuit easily occurs in a see-through thin film solar module.
