    • A polymeric linking agent enables the manufacture of photovoltaic cells at low temperatures ( ° 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.
    • 聚合物连接剂使得能够在柔性基底上包括例如聚合物基底的低温(<约300℃)下制造光伏电池。 光伏电池可以通过相对简单的连续制造工艺制造,例如,卷对卷工艺,而不是间歇工艺。 导致液体电解质在较低温度下凝胶化的方法和组合物也有助于柔性光伏电池的制造。 还描述了改善光伏材料对基底的粘附性并且产生机械稳定的纳米颗粒制剂的方法和化学结构。 另外,与感光染料共同吸附到相互连接的半导体氧化物纳米粒子材料的表面的共同敏化剂通过改善光电池的电荷转移效率和减少电子从互连的半导体氧化物纳米颗粒材料向背转移而提高了光电池的效率 敏化染料。
