- Short description of contents:
- CdTe polycrystalline thin film solar cells are highly scalable devices, showing stable performance and high efficiencies. A recrystallization treatment prior to the back contact deposition is essential for obtaining high efficiencies. Heat treatment in chlorine atmosphere (CdCl2) promotes grain growth, intermixing between CdS and CdTe layers and passivation of the grain boundaries. An alternative method has been previously introduced on close space sublimated (CSS) CdTe devices, consisting in treating CdTe layers in the presence of a gas belonging to the Freon© family at 400 °C. In this work, the application of this novel “activation process” on physical vapor deposited stacks is described.
A comparison between physical/chemical features of the CdCl2 and Freon treated layers is also presented.
