Abstract

Molybdenum bilayers have been used as back contacts for CIGS and CZTS based solar cell for years. Mo bilayer films undergo a heat treatment during the CIGS/CZTS deposition process which in turn changes the stress and morphological properties and affects the adhesion and morphological features of CIGS/CZTS layers. This work reports in-situ studies of Mo stress variation during anneals ranging from 20°C to 500°C and compares its morphological and electrical properties before and after heating to develop a thermally stable Mo bilayer. We have also used a low tensile stress bilayer developed in this way to demonstrate CZTS and CIAGS films with good adhesion properties.
