The performance of CdTe solar cells as prototype of thin film solar cells strongly depends on film morphology. The needs for high solar cell performance using thin film materials will be addressed covering nucleation and growth control of thin film materials. In order to understand the basic growth mechanisms and their impact on cell performance, we have systematically investigated the growth of CdTe...
CdTe solar cells are strongly influenced in their performance by the morphology of the absorber layer. Therefore, we have systematically investigated CdTe film formation deposited by close space sublimation. At low sample temperature the films tend to form compact layers with preferred (111) orientation which is lost at elevated temperatures above 420°C. For CdS layers without (0001) texture there...
We have systematically investigated the growth of CdTe thin films by Close Spaced Sublimation (CSS). Thin films of CdTe were deposited onto CdS substrates held at temperatures in the range 250 to 550 °C. The effect of substrate temperature and evaporation rate on structure and surface morphology of CdTe films were investigated. Up to 450 °C substrate temperature the growth rate was almost constant...
