Semiconductive inks

Nanomaterials have enabled innovation in processes and products in industries as diverse as electronics, chemicals, automotive and agribusiness. Following this boom, the need to obtain stable colloidal dispersions (dyes) of these nanomaterials has become evident. Our synthesis strategy allows obtaining self-functionalized nanomaterials without incorporating chemical stabilizing agents. This ensures that the physical and chemical properties of the nanoparticles are preserved both in liquid dispersion and in final applications in thin films. The Center for Materials Research and Innovation (CIDEMAT) has developed the following Semiconductive Inks: nickel oxide ink (NiOx), copper sulfide (CuxS), copper oxide (Cu2O), zinc oxide (ZnO), cobalt oxide (CoxO), iron oxides (FexOy), magnesium oxide (MgOx), titanium oxide (TiO2) and tin oxide (SnO2). These dispersions have been successfully tested in the development of state-of-the-art solar cells in national and international laboratories. In this case, nanoparticle dispersions enhance the implementation of solution-based manufacturing processes, which generates an increase in competitiveness by reducing manufacturing costs and increasing production speed compared to other methods.
