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.
