Influence of annealing on microstructural and photoelectrochemical characteristics of CuSCN thin films via electrochemical process

Copper(I) thiocyanate (CuSCN) as a hole-transport material for large-area opto/electronics

“…Fabrication temperatures and financial costs are minimized because post-deposition thermal annealing is often not a requirement, although a slight increase in the optical band-gap was observed following high temperature annealing [79]. However, the necessity to deposit the semiconductor onto a conductive surface limits the applicability of this method.…”

Anodized ZnO nanostructures for photoelectrochemical water splitting

“…PEC characteristics of samples were measured via chopping method [4,10,17,18] and with/without illumination [22][23][24] at a scan rate of 25 mV/s from −0.5 to +0.5 V vs. SCE. A 300 W Xe lamp (Perkin Elmer Model PE300UV) with AM 1.5 filters were used as the simulated sunlight and the intensity was calibrated to 100 mW/cm 2 .…”

“…The carrier concentration was extracted as follows [17,18]: where e is the electronic charge, A is the illuminated surface area, N D refers to the carrier concentration of the semiconductor, E FB is the flat-band potential of the semiconductor, ε is the dielectric constant of ZnO, and ε 0 is the permittivity in vacuum. B is assigned to 1 or −1 for n-type and p-type semiconductors, respectively.…”

“…Among these methods, electrochemical deposition is widely adopted as it can be conducted in the ambient environment, which can reduce the preparation cost required for high temperature and high vacancy reaction vessel [17,18]. Electrochemical method also offers several advantages including low cost and possibility of large-scale deposition in comparison with other deposition techniques [17,18]. For instance, Wu et al [19] reported that anodic deposited ZnO nanoneedles via constant current in a saturated alkaline solution containing 4.0 M KOH and 1.0 M Zn(NO 3 ) 2 .…”

Bath temperature and deposition potential dependences of CuSCN nanorod arrays prepared by electrochemical deposition

“…Crystalline thin films of CuSCN can be deposited by a variety of methods such as dip-, and spray-coating or doctor-blading of commercial CuSCN organic solutions [14,15], successive ionic adsorption and reaction [16,17], chemical bath deposition [16], and electrochemical deposition [1,[18][19][20][21][22][23]. Recently, one-dimensional nanostructured semiconductors have attracted great attention due to their high surface areas, good charge transport properties, and special light-trapping effect.…”
