To optimize materials and devices for solar photoelectrochemical hydrogen production, a detailed understanding of the chemical and electronic properties, in particular at the reactive surfaces and interfaces, is needed. In this review article we will

Solar cells based on kesterite-type Cu2ZnSnS4 (CZTS) were fabricated on molybdenum coated soda lime glass by evaporation using ZnS, Sn, Cu, and S sources. The coevaporation process was performed at a nominal substrate temperature of 550°C and at a s

Titanium has been incorporated in CuInS 2 thin films and devices by diffusion of Ti from the substrate during the CuInS 2 co-evaporation growth process. The CuInS 2 crystal structure is unaffected but the grain size is reduced compared to Ti-free ref

We report on the incorporation of molybdenum into tungsten oxide by co-sputtering and its effect on solar-powered photoelectrochemical (PEC) water splitting. Our study shows that Mo incorporation in the bulk of the film (WO3:Mo) results in poor PEC p

Thin CuGaSe 2 films were deposited by vacuum co-evaporation and characterized for their structure, properties and performance as hydrogen-evolving photoelectrodes. The 0.9 μm thick films were nearly stoichiometric with very slight copper deficiency

Polycrystalline tungsten oxide films of 1–1.2μm thickness were prepared by reactive sputtering at elevated substrate temperature (270 °C) and under different oxygen partial pressures in the range from 0.8 to 2.1 mTorr. At the lowest partial press

In the context of photoelectrochemical water-splitting, tungsten oxide films have been fabricated at low processing temperatures ( 250 ∘ C ) by reactive sputtering from tungsten targets in an argon/oxygen ambient. The films have a dense, compact mo

The investigation presented in this paper is related to the electrochromic (EC) behavior of sputtered and CVD deposited films of WO 3 and W/Mo based mixed oxide films. The electrochromic effect is a reversible change in the film transmittance under a
