|
Molybdenum (Mo) degrades under the influence of damp heat, thereby reducing the output of CIGS PV. In this study, Mo layers were deposited on a glass substrate by magnetron sputtering, thereby varying the deposition pressure and the addition of selenium. These samples were thoroughly analysed and degraded at 60 degrees C/60\% relative humidity (RH) and 85 degrees C/85\% RH. The degraded non-selenised Mo samples showed a volume increase and the formation of a bilayer structure. Measurements indicated that the top layers consist of MoOx with x approximate to 2.88 when degraded at 60 degrees C/60\% RH. The selenised layers formed multilayer structures and needles and spheres of both MoOx and selenium containing materials. We conclude that degradation of Mo can cause a volume increase and the complete loss of conductivity. Furthermore, it was observed that selenium greatly influence of the degradation of Mo.
