Abstract

The invention discloses a preparation method of light trapping glass for a thin film solar cell. The method comprises the following steps: S1, immersing a glass substrate into a piranha solution and cleaning the glass substrate; S2, placing the glass substrate in a magnetron sputtering cavity, and adopting Ar ion beams to bombard the surface of the glass substrate for further cleaning of the glasssubstrate; S3, adopting an AZO target with Al dosage concentration being 0.5wt%-1.5wt% as a target material, and growing a first AZO thin film by sputtering with a radio-frequency and direct-currentcoupled sputtering technology; S4, adopting an AZO target with Al dosage concentration being 1.5wt%-2.5wt% as a target material, and growing a second AZO thin film by sputtering with the radio-frequency and direct-current coupled sputtering technology; S5, adopting an Ag target material, and growing an Ag thin film by sputtering with the radio-frequency and direct-current coupled sputtering technology; S6, adopting an AZO target with Al dosage concentration being 2.5wt%-3.5wt% as a target material, and growing a third AZO thin film by sputtering with the radio-frequency and direct-current coupled sputtering technology. With adoption of the method, haze and electrical properties of the light trapping glass can be improved, and AZO transparent conducting glass with high light transmittance and a light trapping function can be obtained.

Description

technical field [0001] The invention relates to the field of glass manufacturing, in particular to a method for preparing light-trapping glass for thin-film solar cells. Background technique [0002] In recent years, zinc oxide (ZnO)-based transparent conductive films have attracted much attention. Typical applications include flexible electronic products, silicon-based thin-film solar cells, flat panel displays, etc. There are many doping elements to improve the conductivity of ZnO, but aluminum doping is one of the most promising. [0003] AZO thin film is a kind of transparent conductive film, which exhibits good transparent conductive properties at an appropriate doping concentration, but currently only one kind of doping concentration target is used to prepare the obtained AZO monolayer film, and it needs to be heated to The AZO film with better photoelectric performance is prepared, which affects the performance of the film.
