METHOD FOR MANUFACTURING THIN FILMS OF CUBI2O4 FOR PHOTOELECTROCHEMICAL APPLICATIONS

Modified Titania Films for Photoelectrochemical Applications

TiO2 is recognized as a photocatalytic material and has been widely used because of its high functionality, long –term stability and non-toxicity. [1]However, because the band gap of pure TiO2 for anatase crystalline phase is as high as 3.2ev, TiO2 shows only high reactivity under ultraviolet light. In order to make the better use with ideal energy source, sunlight, people have tried several mo...

Effect of Annealing on Physical Properties of Cu2ZnSnS4 (CZTS) Thin Films for Solar Cell Applications

Cu2ZnSnS4 (CZTS) thin films were prepared by directly sputteringCu (In,Ga)Se2 quaternary target consisting of (Cu: 25%, Zn: 12.5%, Sn; 12.5%and S: 50%). The composition and structure of CZTS layers have beeninvestigated after annealing at 200 0C, 350 0C and 500 0C under vacuum. Theresults show that recrystallization of the CZTS thin film occurs and increasingthe grain size with a preferred orie...

Characterization of iron oxide thin films for photoelectrochemical hydrogen production

Simulation of Fabrication toward High Quality Thin Films for Robotic Applications by Ionized Cluster Beam Deposition

The most commonly used method for the production of thin films is based on deposition of atoms or molecules onto a solid surface. One of the suitable method is to produce high quality metallic, semiconductor and organic thin film is Ionized cluster beam deposition (ICBD), which are used in electronic, robotic, optical, optoelectronic devices. Many important factors such as cluster size, cluster...

Self-assembled 2D WSe2 thin films for photoelectrochemical hydrogen production

WSe2--a layered semiconductor that can be exfoliated into atomically thin two-dimensional sheets--offers promising characteristics for application in solar energy conversion. However, the lack of controllable, cost-effective methods to scalably fabricate homogeneous thin films currently limits practical application. Here we present a technique to prepare controlled thin films of 2D WSe2 from di...
