Title:
THIN-FILM SOLAR ARRAY HAVING MOLYBDENUM-CONTAINING REAR ELECTRODE LAYER
Document Type and Number:
WIPO Patent Application WO/2009/076690
Kind Code:
A3
Abstract:
The thin-film solar array according to the invention comprises a rear electrode layer comprising at least 50 atom % of Mo, which in addition to the common contaminants comprises 0.1 to 45 atom % of at least one element from the group of Ti, Zr, Hf, V, Nb, Ta, and W, 0 to 7.5 atom % of Na and 0 to 7.5 atom % of at least one element forming a compound with NA that has a melting point > 500ºC. The rear electrode layer has good long-term resistance and bonding with the CIGS absorber layer. In addition, the constancy of the alkali metal integration in the absorber layer is improved.
