METHOD OF FORMING ORGANIC THIN FILM AND SOLAR CELL FORMED BY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method of forming an organic thin film uniform to a substrate.SOLUTION: A method of forming an organic thin film includes: a first step of charging droplets of a precursor of an organic semiconductor and accelerating them by electrostatic force, and forming an initial stage thin film 42 of an organic semiconductor by colliding the droplets with a silicon single crystal substrate 41; and a second step of forming an organic semiconductor coating film by coating organic semiconductor solution on the silicon single crystal substrate 41 on which the initial stage thin film 42 is formed. This two stage film forming process can form a uniform organic semiconductor thin film on a hydrophobic silicon single crystal substrate.
