Molybdenum films are investigated on stainless steel substrates coated with polysilazane based sol-gel and SiO layers for flexible CIGS solar cell applications. Thermal stability of the multilayer has been studied. The thickness of polysilazane films are significantly reduced (17%) after heat treatment suggesting a thermal degradation. Four different microstructures were found for Mo films by varying argon total pressure from 2.6 × 10 Pa to 2.6 Pa. It was shown that continuous films, low sheet resistance (0.5 ω/□) and well facetted grains can be achieved when Mo films are deposited on heated substrates at homologous temperature, T of 0.2.
