Studies Conducted at Case Western Reserve University on Photoelectrochemicals Recently Reported [Synthesis and Photoelectrochemical Properties of (Cu2Sn)(x)Zn3(1-x)S3 Nanocrystal Films]

By a News Reporter-Staff News Editor at Biotech Week -- Research findings on Biotechnology are discussed in a new report. According to news reporting out of Cleveland, Ohio, by NewsRx editors, research stated, "This work provides new routes for developing efficient photoelectrodes for photoelectrochemical (PEC) water splitting using a low-cost electrophoretic film preparation method. A series of (Cu2Sn)(x)Zn3(l-x)S3 (0

Our news journalists obtained a quote from the research from Case Western Reserve University, "Morphologies including particles, rods, and wires are obtained by tuning the composition of the NCs. (Cu2Sn)(0.75)Zn0.75S3 (Cu2ZnSnS4) has a pure kesterite structure, but an increase in the Zn content results in a kesterite-wurtzite polytypism. (Cu2Sn)(x)Zn3(1-x)S3 films are fabricated from their colloidal solutions via electrophoretic deposition, and the PEC properties of these films with p-type character have been examined under water-splitting conditions. It is shown that the photocurrent varies as a function of film thickness as well as chemical composition."

According to the news editors, the research concluded: "The produced (Cu2Sn)(0.45)Zn1.65S3 (x = 0.45) film has the highest photocurrent, and the incident photon to current conversion efficiency is improved compared with previously reported results of Cu2ZnSnS4 photocathodes."
