Abstract
The kinetics of nucleation process and growth of the electrodeposited CdS and CdTe nanocrystals for thin-film solar cells has been studied using chronoamperometry method. Comparison of experimental data to theoretical models is carried out. It is established that the nucleation and growth of CdTe and CdS; depending on electrodeposition conditions; is described by regularities of two-dimensional 2D or three-dimensional 3D growth with the instant nucleation complicated by the subsequent diffusion. In the electrodeposition of CdS on glassy-carbone electrode occurs two-dimensional 2D instant nucleation mechanism. Cadmium sulfide deposited on SnO 2 /glass electrode by three-dimensional 3D growth with the instant nucleation. Nucleation and growth of CdTe on the surface of CdS goes by two-dimensional 2D instant nucleation mechanism. The surface of CdS layer; deposited by electrodeposition method onto SnO 2 /glass substrate; represent a dense layer of oriented particles with size ~20 nm. Found out presence of particles with smaller sizes ~8-20 nm.
