Kurzbeschreibung (Abstract)
Intermediate highly resistive layers of transparent undoped oxide materials are known to improve the characteristics of thin film solar cells, as observed for SnO₂ used in CdTe solar cells with reduced CdS layer thickness. Comparative photoemission spectroscopy studies were carried out on commercial undoped and fluorine doped SnO₂ prepared by spray-pyrolysis, revealing that the Fermi level positions of the surfaces of both commercial samples are identical and degenerate. The commercial SnO₂ was compared to SnO₂ prepared by RF magnetron sputtering under different oxidation conditions. The sputtered samples were only weakly n-doped. Additionally, the influence of different sample treatments was investigated.
