On 2017 December 5, Ahed Zyoud, Khaled Murtada, Hansang Kwon, Hyun-Jong Choi, Tae Woo Kim, Mohammed H.S. Helal, Maryam Faroun, Heba Bsharat, DaeHoon Park and Hikmat S. Hilal published a new study in Solid State Sciences 75 (2018) 53e62 titled "Copper selenide film electrodes prepared by combined electrochemical/chemical bath depositions with high photo-electrochemical conversion efficiency and stability". The article indicated or concluded that New copper selenide film electrodes, prepared by electrochemical deposition followed by chemical bath deposition, showed relatively high PEC conversion efficiency values (~14.6%) for te asprepared film electrode. The new films also showed relatively high stability under PEC conditions. The enhanced PEC characteristics of the new films are attributed to their ability to combine the advantages of both electrochemically deposited and chemical bath deposited film electrodes. The results show how PEC properties of metal chalcogenide film electrodes can be enhanced by simple combined preparation techniques. Annealing at relatively high temperatures affects the film morphology and composition and lowers its PEC characteristics.
