Abstract

Kinetics of recrystallization in screen-printed polycrystalline CdS films has been investigated by X-ray structure analysis and optical microscopy. The relation between the crystallite size, crystallite orientation and the macrostrain, as well as their dependence on heat treatment regimes is established. It is shown that single-phase CdS films having a thick- ness of some tens microns, large grain size and low residual strain can be produced at opti- mum technological regimes. The films obtained are suitable for fabrication of CdS/CdTe solar cells.
