“…[15] Furthermore, the development of thin-film fabrication techniques enable the preparation of high-quality CuInS 2 photoelectrodes by a low-cost electrodeposition method. [16][17][18] For efficient PEC H 2 evolution, efficient separation of the photogenerated electrons and holes is extremely important. We have reported that surface modification using thin n-type layers of, for example, CdS enhances the cathodic photocurrent from CuGaSe 2 , Cu-(In,Ga)Se 2 , and Cu 2 ZnSnS 4 photocathodes through the formation of a p-n junction on the surface of the photocathodes.…”

Porous films of p-type CuInS 2 , prepared by sulfurization of electrodeposited metals, are surface-modified with thin layers of CdS and TiO 2 . This specific porous electrode evolved H 2 from photoelectrochemical water reduction under simulated sunlight. Modification with thin n-type CdS and TiO 2 layers significantly increased the cathodic photocurrent and onset potential through the formation of a p-n junction on the surface. The modified photocathodes showed a relatively high efficiency and stable H 2 production under the present reaction conditions.Being a clean energy carrier, hydrogen produced by solardriven water splitting has attracted much attention as a potential solution to our energy-and environment-related problems. Photoelectrochemical (PEC) water splitting using semiconductor thin films as photoelectrodes is a promising and effective approach for hydrogen generation. [1][2][3][4] Since the first demonstration of TiO 2 photoelectrodes in 1972, a variety of semiconductor electrodes in different configurations have been investigated to obtain efficient solar-to-hydrogen conversion. [5][6][7][8][9][10] Although many remarkable improvements have been achieved in this field, the development of active semiconductor materials for high-quality electrodes enabling efficient PEC performance remains a challenge.

“…Although Bi et al (2016) eliminated the dendritic morphology of Cu on Mo via a pulse current electrodeposition method, the problem of dendritic clusters appeared again after the Cu thickness was reduced. To fabricate dendritic-cluster-free and smooth Cu films via electrodeposition, numerous studies have been conducted (Norkus et al, 2005;Moffat et al, 2007;Lee et al, 2012). Among them, adding organic additives in the electrodepositing solution could help reduce the surface roughness of Cu films and improve their flatness (Long et al, 2006;Favry et al, 2008).…”

CuSbS2, as a direct bandgap semiconductor, is a promising candidate for fabricating flexible thin-film solar cells due to its low grain growth temperature (300°C–450°C). Uniform and highly crystalline CuSbS2 thin films are crucial to improving device performance. However, uniform CuSbS2 is difficult to obtain during electrodeposition and post-sulfurization due to the “dendritic” deposition of Cu on Mo substrates. In this study, Sb/Cu layers were sequentially pulse electrodeposited on Mo substrates. By adjusting the pulse parameters, smooth and uniform Sb layers were prepared on Mo, and a flat Cu layer was obtained on Sb without any dendritic clusters. A two-step annealing process was employed to fabricate CuSbS2 thin films. The effects of temperature on phases and morphologies were investigated. CuSbS2 thin films with good crystallinity were obtained at 360°C. As the annealing temperature increased, the crystallinity of the films decreased. The CuSbS2 phase transformed into a Cu3SbS4 phase with the temperature increase to 400°C. Finally, a 0.90% efficient solar cell was obtained using the CuSbS2 thin films annealed at 360°C.
