Abstract Electrodeposited CdS and CdTe thin films have been fabricated into solar cells with a CdS/CdTe heterojunction. The CdTe films were made by varying two parameters, viz. the concentration of tellurium ions in the deposition solution and the quasi-rest potential (QRP) of the deposit. The properties of the completed cells were examined as a function of those preparation variables. Cell efficiency varied with both QRP and tellurium ion concentration. Whilst chemical analytic methods showed no compositional variation between cells, morphological studies showed that the most efficient cells had the largest grain size. Electrical and capacitance measurements were used to show that the density of interband states and of junction interface states increased with structural imperfection. The major losses in the solar cell parameters increased with increased polycrystalline structure.
