Title:
KESTERITE LAYER FABRICATION FOR THIN FILM SOLAR CELLS
Document Type and Number:
WIPO Patent Application WO/2012/055737
Kind Code:
A3
Abstract:
A Kesterite film is vacuum deposited and annealed on a substrate. Deposition is conducted at low temperature to provide good composition control and efficient use of metals. Annealing is conducted at a high temperature for a short period of time. Thermal evaporation, E-beam evaporation or sputtering in a high vacuum environment may be employed as part of a deposition process.
