The invention relates to the use of electrically conductive inks, said inks comprising electrically conductive powder and electrically conducting fibres, wherein the aspect ratio of the fibres is greater than 2:1. The inks are used to form electrically conductive layers, especially in optoelectronic devices such as solar cells. The layers have considerably reduced electrical resistance than if the electrically conductive powder were used alone. L'invention concerne l'utilisation d'encres électriquement conductrices, encres qui contiennent une poudre électriquement conductrice et des fibres électriquement conductrices. Le rapport l/d des fibres est supérieur à 2:1. Les encres sont utilisées pour fabriquer des couches électriquement conductrices, notamment dans des dispositifs optoélectroniques, tels que des cellules solaires. Les couches présentent une résistance électrique considérablement réduite par rapport aux cas où seule la poudre électriquement conductrice est utilisée.
