A polymeric linking agent enables the manufacture of photovoltaic cells at low temperatures (< about 300 ~C) on flexible substrates, including, for example, polymeric substrates. Photovoltaic cells may be fabricated by a relatively simple continuous manufacturing process, for example, a roll-to-roll process, instead of a batch process. Processes and compositions that cause the gelling of liquid electrolytes at relatively low temperatures also facilitate the fabrication of flexible photovoltaic cells. Methods and chemical structures that improve the adhesion of a photovoltaic material to the substrates and that produce mechanically stable nanoparticle formulations are also described. Furtehrmore, co-sensitizers that co-adsorb with a sensitizing dye to the surface of an interconnected semiconductor oxide nanoparticle material increase the efficiency of photovoltaic cells by improving their charge transfer efficiency and reducing the back transfer of electrons from the interconnected semiconductor oxide nanoparticle material to the sensitizing dye.

Un agent de liaison polymère assure la fabrication de cellules photovoltaïques à basses températures (< environ 300 ?·¿C) sur des substrats souples, y compris des substrats polymères par exemple. Les cellules photovoltaïques peuvent être fabriquées au moyen d'un procédé de fabrication en continu relativement simple, par exemple, un procédé bobine-à-bobine, au lieu d'un procédé par lots. Les procédés et les compositions qui produisent la gélification des électrolytes liquides à des températures relativement basses facilitent également la fabrication de cellules photovoltaïques souples. Cette invention concerne également des procédés et des structures chimiques qui améliorent l'adhérence d'un matériau photovoltaïque sur les substrats et qui produisent des formulations de nanoparticules stables d'un point de vue mécanique. De plus, des co-sensibilisateurs qui sont co-adsorbés avec un colorant sensibilisateur sur la surface d'un matériau à nanoparticules d'oxyde semi-conducteur inter-reliées améliorent l'efficacité des cellules photovoltaïques du fait qu'ils améliorent leur efficacité de transfert de charge et réduisent le transfert inverse des électrons du matériau à nanoparticules d'oxyde semi-conducteur inter-reliées, sur le colorant sensibilisateur.
