Junction Formation in CuInSe{sub 2} Based Thin Film Devices

Description: The nature of the interface between CuInSe{sub 2} (CIS) and the chemical bath deposited CdS layer has been investigated. We show that heat-treating the absorbers in Cd- or Zn-containing solutions in the presence of ammonium hydroxide sets up a chemical reaction which facilitates an extraction of Cu from the lattice and an in-diffusion of Cd. The characteristics of devices made in this manner suggest that the reaction generates a thin, n-doped region in the absorber. It is quite possible that th… more

Advanced CIGS Photovoltaic Technology: Annual Technical Report, 15 November 2001-14 November 2002

Description: Energy Photovoltaics, Inc. (EPV) has consistently pursued a vacuum-based approach to CIGS production, using novel linear-source technology and standard soda-lime glass substrates. It has also chosen to develop processing methods with worker safety in mind. These choices result in layers having controllable purity and low physical defects, and production without significant hazards. Considerations such as these are important in helping to minimize the processing costs of CIGS. Technically, thin-… more

Advanced CIGS Photovoltaic Technology: Final Subcontract Report, 15 November 2001--13 February 2005

Description: The principal objective of Energy Photovoltaics, Inc., is to develop the best CIGS large-area module process based on capability of implementation on EPV's large-scale processing equipment. The first requirement was to develop recipes for CIGS, junction formation, and a high-quality ZnO window that together are capable of producing small-area devices with efficiencies in excess of 13%. The second requirement was to significantly improve the uniformity of all layers (Mo, CIGS, CdS, and ZnO) on l… more
