In this study, Cd_1−xZn_xS_ySe_1−y (0 ≤ x = y ≤ 0.35) photoelectrodes are deposited via inexpensive facile chemical bath deposition. The effects of Zn and S doping on the compositional, microstructural, electrical, and optical properties of thin films were analysed. The electrochemical photovoltaic (EPV) cell of configuration Cd_1−xZn_xS_ySe_1−y/0.25M sulfide/polysulfide/C was assembled to examine the different performance parameters in light and in dark conditions. An EPV cell fabricated with the Cd_1−xZn_xS_ySe_1−y (0 ≤ x = y ≤ 0.075) photoelectrode exhibited a maximum photoconversion efficiency of 3.18%. This performance can be attributed primarily to the enhanced light‐absorption ability of the material because of the enhanced rough microstructure and low recombination of photo‐injected electrons with the electrolyte. The photovoltaic (PV) performance is significantly enhanced after doping CdSe with Zn and S.

用于电化学光伏电池的Cd（Zn，S）Se四元薄膜

在这项研究中，镉_1-x的Zn _X小号_ý硒_1-Y（0≤ X = ý ≤0.35）光电极通过廉价的容易化学浴沉积来沉积。分析了Zn和S掺杂对薄膜的组成，微观结构，电学和光学性质的影响。组装配置为Cd _1-x Zn _x S _y Se _1-y /0.25M硫化物/聚硫化物/ C的电化学光伏（EPV）电池，以检查在明亮和黑暗条件下的不同性能参数。用Cd _1-x Zn _x S _y Se制成的EPV电池_1-Y（0≤ X = ý ≤0.075）光电极表现出3.18％的最大光转换效率。这种性能主要归因于材料增强的光吸收能力，这是由于增强了粗糙的微观结构以及光注入电子与电解质的低重组率。在CdSe中加入Zn和S后，光伏（PV）性能得到显着提高。
