The effects of substrate and source temperatures, deposition disruption and material preparation of CdTe thin films, fabricated in a home-made CSS system are investigated. It is demonstrated that packing CdTe powder prior to deposition has a positive effect on growth rate. Furthermore, grain size, thin film thickness and uniformity strongly depend on substrate and source temperatures. Growth disruption during the sublimation process showed island formation, island size increase and island coalition in consecutive steps.
