Description

A low-temperature routine to realize inorganic amorphous electron-transport layers (ETLs) is of great importance for the commercialization of perovskite solar cells. The fabrication of ETLs at low temperature is energy saving and compatible with flexible substrates. In this work, titanium thin films are synthesized at low temperature (below 100 ℃) with a polymer template sol-gel method based on the amphiphilic diblock copolymer polystyrene-b-polyethylene oxide (PS-b-PEO), in combination with selective incorporation of the titanium precursor ethylene glycol-modified titanate (EGMT). Morphology tailoring of titanium thin films in the low-temperature process is achieved by managing phase separation of the polymer template. The solvent category for the sol-gel solution is varied to tune the thin film morphologies. Scanning electron microscopy is used to study the structure of the titania films.
