The cell has a conductive substrate with an electrode coating. A photoactive layer is formed on the electrode coating. An electrolyte medium is interposed between an electrolyte layer and a counter-electrode forming assembly. The electrolyte medium includes ionic charges that form a reversible redox cell. The electrolyte medium comprises a matrix based on textile web or a stack of layers including the textile web. The textile web or the stack of layers is impregnated by a solubilizing liquid that solubilizes ionic charges, where the liquid includes a solvent. An independent claim is also included for a method for manufacturing a photovoltaic cell. La présente invention a pour objet une cellule photovoltaïque à colorant, comprenant : un ensemble substrat conducteur/couche photoactive, ladite couche photoactive comprenant un matériau porteur de colorant et un colorant présent dans ledit matériau porteur de colorant ; un ensemble formant contre-électrode ; et un milieu électrolyte interposé entre ladite couche photoactive et ledit ensemble formant contre-électrode, ledit milieu électrolyte comprenant des charges ioniques formant un couple redox réversible, à l'état solubilisé par un liquide de solubilisation. Selon l'invention, le milieu électrolyte comprend une matrice à base d'une nappe textile (NT) ou d'un empilement de nappes incluant au moins une nappe textile (NT), ladite nappe textile (NT) ou ledit empilement étant imprégné (e) par le liquide (L) solubilisant les charges ioniques.
