CBD‐Cd_1−xZn_xS thin films and their application in CdTe solar cells

Abstract

PACS 78.66.Hf, 81.05.Dz, 81.15.Lm, 84.60.Jt Composition, optical properties, structure properties, and surface morphology of thin films of Cd 1-x Zn x S (x ≤ 10%) prepared by chemical bath deposition (CBD) are reported. The best cell efficiency was 15.7%. It used a Cd 1-x Zn x S window layer, was confirmed by NREL (V oc = 840.1 mV, J sc = 24.81 mA/cm 2 , and FF = 75.55%), and had a CTO/ZTO/Cd 0.92 Zn 0.08 S/CdTe cell structure. The use of low zinc concentration in the Cd 1-x Zn x S layer and interdiffusion between Cd 1-x Zn x S and CdTe layers were assumed to be the reasons for maintaining high V oc and FF.

Fabrication of Cd1−xZnxS films with controllable zinc doping using a vapor zinc chloride treatment

“…Various methods have been used to produce Cd 1 À x Zn x S films, including photochemical deposition [9], co-evaporation [10], chemical spray deposition [11] and chemical bath deposition [12]. Most methods, especially the solution deposition methods, require an annealing process in order to improve the film quality.…”

Structure, Composition and Optical Properties of Non Aqueous Deposited ZnCdS Nanocrystalline Film

“…The atomic percentage and weight percentage of Zn, Cd and S are given in table 2. Zhou et al [20] have determined the elemental ratio of ZnCdS thin film and it is observed that Zn ratio is much less than the Cd ratio.…”

Experimental Study on Structural, Optical and Electrical Properties of Chemical Bath Deposited CdZnS Thin Films

“…Various thin-film deposition technique like vacuum evaporation, spray pyrolysis, dip technique, electrodeposition, chemical bath deposition (CBD), SILAR has been used to synthesize CdZnS thin films [7][8][9][10][11]. Among these deposition techniques, CBD is widely accepted as the preferable method to synthesize CdZnS thin film.…”
