Titanium dioxide (TiO2) is a versatile material used in a variety of applications, including photocatalysis, photovoltaics, sensing, and environmental remediation. The properties of TiO2 are influenced by its defect disorder, with oxygen vacancy (V0) being a prominent defect that has been widely studied. Defective TiO2 materials, particularly those containing V0 …

1. Introduction. Titanium dioxide (TiO 2) thin films are produced by atomic layer deposition (ALD) since the beginning of the 90′s [1].TiO 2 films can have an amorphous or crystalline structure with anatase or rutile phases, both tetragonal. They are of great interest since their structural, optical, and electrical properties offer flexibility driven by the existence of …

Introduction. The ability of titanium dioxide (titania, TiO 2) to act as a photocatalyst has been known for 90 years (Renz 1921), and its role in the "chalking" of paint (formation of powder on the surface) is well known (Jacobsen 1949).Interest in the application of the photocatalytic properties of TiO 2 was revived when the photoelectrolysis of water was …
The electron-transporting layer (ETL) plays a critical role in improving the charge extraction and suppressing the carrier recombination in planar perovskite solar cells (PSCs). Compact titanium dioxide (TiO 2) film is a widely used as an ETL in conventional n-i-p PSCs.
Low-temperature processed electron transport layer (ETL) of TiO2 that is widely used in planar perovskite solar cells (PSCs) has inherent low carrier mobility, resulting in insufficient photogenerated electron transport and thus recombination loss at buried interface. Herein, we demonstrate an effective strategy of laser embedding of p-n homojunctions in the …

Visually black, electrically leaky, amorphous titania (am-TiO2) thin films were grown by atomic layer deposition (ALD) for photocatalytic applications. Broad spectral absorbance in the visible range and exceptional conductivity are attributed to trapped Ti3+ in the film. Oxidation of Ti3+ upon heat treatment leads to a drop in conductivity, a color change from black to white, …
