Document Type and Number:
WIPO Patent Application WO/2019/093558
Kind Code:
A1
Abstract:
The present invention relates to a technique for manufacturing a light-transmitting compound thin film by selectively forming a light absorbing thin film layer on an electrode by using an electrochemical deposition method and a selective electrodeposition method. According to the present invention, provided is a method for preparing a compound thin film, comprising: a circuit configuring step of connecting an electrochemical cell to a voltage application device or a current application device to configure an electrodepositing circuit, the electrochemical cell including an electrolytic solution prepared by mixing a predetermined precursor and a solvent, and a working electrode in the form of an electrode patterned with a specific pattern formed on a substrate prepared in advance; and a thin film forming step in which a thin film is selectively electrodeposited only in a partial region of the electrode according to the shape of the electrode patterned with the specific pattern by applying a reduction voltage or current to the working electrode by using the voltage application device or the current application device. In addition, according to the present invention, in order to prevent shunt and recombination loss caused by exposure of the side or cut surface of the patterned electrode for the purpose of preparing a light-transmitting thin film solar cell, provided is a method for preparing a light-transmitting compound thin film including an oxide-based recombination preventing film (or a passivation film) on the side or cut surface of the patterned electrode.
