Abstract: A polymeric linking agent enables the manufacture of photovoltaic cells 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.

Abstract: In one aspect, the invention provides photovoltaic modules. In one embodiment, a photovoltaic module includes a plurality of photovoltaic cells, at least two of which include a photosensitized nanomatrix layer and a charge carrier media. Preferably, the cells further include a catalytic media layer. The photovoltaic cells are disposed between a first electrical connection layer and a second electrical connection layer. In one embodiment, the cells are interconnected in series and the electrical connections layers each include conductive and insulative regions.

Abstract: A flexible photovoltaic cell integrated onto an active card, such as a greeting card or “smart” card, may be fabricated separately and then integrated with additional electronics on the active card. Alternatively, the photovoltaic cell may be fabricated on the active card itself, constituting, if desired, part or all of its surface design.

Abstract: 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.
