COMPOSITION FOR PASSIVATION FILM, SEMICONDUCTOR SUBSTRATE WITH PASSIVATION FILM AND MANUFACTURING METHOD THEREOF, AND SOLAR BATTERY ELEMENT AND MANUFACTURING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide: a composition for a passivation film which allows a passivation film having a desired shape to be formed by a simple and convenient method, and is excellent in storage stability and compactness; a semiconductor substrate provided with a passivation film by use of the composition; a method for manufacturing the semiconductor substrate; a solar battery element; and a method for manufacturing the solar battery element.SOLUTION: A composition for a passivation film comprises: a metal alkoxide compound expressed by the general formula (I) below; water; and a hydrolysis catalyst. [In the general formula (I), M represents any of Nb, Ta, V, Y and Hf; R's are independent of each other and represent alkyl groups each having 1-8 carbon atoms, respectively; and m is an integer of 0-5.]
