Abstract:
1. A method for selectively growing a thin film having AgInS 2 /AgIn 5 S 8 solid mixtures or a thin film having AgIn 5 S 8 structure in continuous process using a same formulation, at least comprising: (a) providing a plurality of substrates; (b) cleaning the substrates; (c) adjusting the temperature, the concentration and the pH-value of a reaction liquid, the reaction liquid is consisted of a first liquid and a second liquid, the first liquid comprises 0.1˜1 M of silver ions (Ag (d) placing the substrates into the reaction liquid; (e) vibrating the reaction liquid by ultrasonic waves such that a thin film is grown on the substrates evenly; and (f) determining whether a number of performing the steps (c), (d) and (e) reaches a predetermined number, and if no, repeating the steps (c), (d) and (e), wherein the predetermined number is 1˜3 when growing the thin film having AgInS
