[en] In the incipient world of functional industrial ceramics with photovoltaic applications, there is a need to reduce production costs while maximizing the systems useful life. The thin contact layers currently being manufactured are based on vacuum systems with high production costs and major problems of accelerated corrosion in photovoltaic applications. The electroless process produces very even and compact layers with very low costs through chelate-based chemicals. These layers have been formulated in this study with a view to obtaining appropriate electric characteristics for an optimum photoelectric performance in the assemblies. The morphological requirements are previously fitted through a glaze that acts as a barrier layer between the deposited coating and the porcelain tile, applied through tape casting. The characterisation of the metal layers obtained is started by SEM, an AFM and the Hall effect in order to determine the morphology and chemical characteristics required for these contact layers. The electric characterisation also allows their capacity for offering an optimum performance in the assemblies to be assessed. Finally, the performance of these layers with respect to corrosion is assessed in order to complete the assessment of their industrial suitability. (Author) 13 refs.
