The invention pertains to a method of making a photovoltaic cell at least comprising the following layers in the following order a first electrode layer, a transparent wide band gap semiconductor layer provided with a layer of a photosensitising dye or pigment which in combination with the semiconductor layer has the ability to spatially separate photogenerated electrons from their positive countercharges, a layer of an electrolyte, a catalyst layer, and a second electrode layer. The method is characterised in that the first electrode layer and the semiconductor layer and/or the second electrode layer and the catalyst layer are deposited on a flexible temporary substrate that is removed later on. The electrode or electrodes, which are deposited on the temporary substrate, are transparent. The invention allows the roll-to-roll manufacture of said photovoltaic cell while providing great freedom in selecting the processing conditions.

L'invention concerne un procédé de production d'une cellule photovoltaïque comprenant au moins les couches suivantes dans l'ordre suivant: une première couche d'électrode, une couche de semi-conducteur transparente à large bande interdite dotée d'une couche d'un colorant ou d'un pigment photosensibilisant en combinaison avec la couche de semi-conducteur et présentant la capacité de séparer dans l'espace les électrons photogénérés de leurs contrecharges positives, une couche d'un électrolyte, une couche catalytique et une seconde couche d'électrode. Le procédé est caractérisé en ce que la première couche d'électrode et la couche de semi-conducteur et/ou la seconde couche d'électrode et la couche catalytique sont déposées sur un substrat flexible temporaire éliminé ensuite. L'électrode ou les électrodes, déposées sur le substrat temporaire, sont transparentes. Cette invention permet la production bobine à bobine de ladite cellule photovoltaïque tout en donnant une grande liberté de choix des conditions de traitement.
