Title:
FABRICATION OF STABLE PEROVSKITE-BASED OPTOELECTRONIC DEVICES
Document Type and Number:
WIPO Patent Application WO/2016/189802
Kind Code:
A1
Abstract:
A method of fabricating a perovskite-based optoelectronic device is provided, the method comprising: forming an active layer comprising organometal halide perovskite; making a solution comprising a hole transport material (HTM) and a solvent, the solvent having a boiling point lower than that of chlorobenzene; and forming a hole transport layer (HTL) by spin-coating the solution on the active layer. The solvents having a boiling point lower than that of chlorobenzene include chloroform and dichloromethane.
