In this study, Cadmium Sulfide (CdS) semiconductor films are electrodeposited on Indium Tin Oxide (ITO) substrates at 80 °C base temperature for different boric acid (H3BO3) ratios. The effect of boric acid on these films is investigated. For this, first of all, the structural change of the films is examined. Among the films obtained with different boric acid ratios, the optimum film is achieved with 0.06 m boric acid doped. From the basic absorption spectra (αhʋ) of the obtained CdS:B films, the variation of hʋ is drawn and it is determined that the CdS:B semiconductor films has a direct band transition. From the basic absorption spectra of the obtained CdS:B films, it is observed that the CdS:B semiconductor films has a direct band transition. In addition, the optical energy bandgap values obtained are in agreement with the values in the available literatures. The results of the structural, optical, and morphological properties of the films produced in this study indicate that among the selected additive ratios, 1% boric acid gives the best and optimum deposition condition. The thin films obtained are also found to be useful as absorber layers in photovoltaic solar cells.

“…Most previous studies on CZTSSe solar cells have only reported the growth of a buffer layer with a thickness of about 50 nm on the surface of the absorption layer using the CBD method, and the use of CdSO 4 ·8/3H 2 O as the traditional Cd-salt. − In addition to CdSO 4, the Cd-salts used to prepare CdS films can also be replaced with CdCl 2 , Cd(CH 3 COO) 2 , or Cd(NO 3 ) 2 . However, to the best of our knowledge, there is still no report on the preparation of CZTSSe/CdS HJT using CdCl 2 or Cd(CH 3 COO) 2 .…”

In the prior art of CZTSSe solar cells, the traditional cadmium salt (Cd-salt) CdSO 4 is widely considered as a common raw material for preparing CdS buffer layers. However, in this study, we systematically demonstrated the phase structure and transmission spectra improvement effect of the other three types of Cd-salts, Cd(NO 3 ) 2 , CdCl 2 , and CdAc 2 , on the CZTSSe/CdS heterojunction (HJT) compared to CdSO 4 . CZTSSe/CdS HJT prepared by Cd(NO 3 ) 2 showed the strongest CdS phonon characteristic peaks at 295.9 and 597.6 cm −1 , indicating a pure crystal phase. The transmittance of CdS films prepared by Cd(NO 3 ) 2 is 20−35% higher than the other three Cd-salts in the light range of 350−1000 nm, which effectively improved the band gap of the films (2.41 eV) and depressed the photon absorption and scattering. Accordingly, CZTSSe solar cells based on the aforementioned Cd-salts showed that Cd(NO 3 ) 2 possessed the best ability to improve the photovoltaic conversion efficiency (PCE), about 5.7% more than the traditional CdSO 4 salt. After Sn 2+ replaced by Sn 4+ in the precursor solution, the PCE of CZTSSe solar cells using Cd(NO 3 ) 2 exceeded 10% (Total area = 0.21 cm 2 , PCE = 10.23%, V OC = 0.485 V, J SC = 31.4 mA/cm 2 , FF = 67.1%, without MgF 2 antireflective layer).

Thin films have been used for many applications. Hydrogen production from solar water splitting has been considered as a key solution to the energy and environmental issues. The tuned band gap alignments in metal chalcogenides/metal oxides heterostructure enable efficient separation of photogenerated electrons and holes, leading to the effective hydrogen production. We sensitize these structures by hydrothermal methods and evaluate the performance toward hydrogen generation. This work shows a brief overview of photoelectrochemical hydrogen production, progress and ongoing sprints. Here, different metal chalcogenides were deposited on metal oxides (TiO2 and Fe2O3) in order to improve the photoelectrochemical performance by reducing recombination of photogenerated electron-hole pairs and facilitate hole transport at the metal chalcogenides/metal oxides/electrolyte interface. The study includes chalcogenides/metal oxides heterostructure designs and electrochemistry and solar hydrogen generation are brought together, illustrating the promise and challenge of photoelectrochemistry.
