The constraints over efficiency improvements in Cu 2 ZnSn(S, Se) 4 photovoltaic cells have prompted the search for alternative replacements. The simultaneous incorporation of (Cu, Zn, S) in the CdSe host lattice with different stoichiometry can be an attractive approach to circumventing the difficulties associated with CZTSSe. This paper reports the non-vacuum deposition technique of a new chalcogenide semiconductor material, Cd 1-x-y Zn x Cu y S z Se 1-z (0 ≤ x + y ≤ z ≤ 0.15) sample-0 to 3), for photoelectrochemical (PEC) solar cell applications. Compositional studies detected Cd, Cu, Zn, Se, and S in the deposits, and chemical analysis identified Cd 2+ , Cu 2+ , Zn 2+ , S 2- and Se 2- in the deposits. Surface micrographs revealed a cauliflower-like morphology having a high surface area, which can provide additional reactive sites for the effective percolation of electrolyte ions. The AFM study showed uniformly distributed hillocks and valleys with the maximum surface to area ratio. The highest efficiency of 1.60% was achieved for Cd 1-x-y Zn x Cu y S z Se 1-z solar cells (sample - 3). These results highlight this new material for further studies.
