Structural, optical and photoelectrochemical properties of brush plated CdSex Te1−x thin films

CdSexTe1−x films have been deposited by the brush plating technique for the first time, on titanium and conducting glass substrates at room temperature. These films were annealed in argon atmosphere at 475◦C for 15 min. Their structural, optical and photoelectrochemical (PEC) properties are presented and discussed. The power conversion efficiency has been found to be 9.0% at 60 mW cm−2 white light illumination. A peak quantum efficiency of 0.7 has been obtained for the films of composition CdSe0.7Te0.3. Donor concentration of 1017 cm−3 and electron mobility of 60 cm2 V−1 sec−1 were obtained
