Abstract :
For optimizing and having reproducibility of the PV-performance of CdTe based solar cells, the quality of the CdS-partner window material plays an important role. One of the main problems to be solved consists in eliminating the pinhole density in the CdS layer, as well as its processing with the suitable geometric granularity (grain size, roughness, barrier dimensions, voids and film thickness). We have started studying CBD-CdS bilayer deposition, as they make possible to get micro and nano CdS-particles, thus allowing us to engineer the particles size that could be embedded and recrystallized afterwards to improve the CdS film quality
