Co-sensitized solar cells have gained more attention due to the ability of energy conversion process by absorbing photons from wide range of the solar spectrum including visible and near-infrared region. TiO₂ electrodes were co-sensitized with PbS/CdS core-shell quantum dots and N719 dye. PbS/CdS/N719 dye-sensitized solar cells were fabricated with poly(ethylene oxide) based solid polymer electrolyte consisting iodide/triiodide redox couple. The iodide ion conductivity of the electrolyte was enhanced by incorporating a binary iodide salt mixture of different size cations, tetrapropylammonium iodide and potassium iodide. The performance of the solar cell was further enhanced by the incorporating TiO₂ P90 nanofiller in the electrolyte. The best solid-state solar cell showed a significantly higher efficiency of 4.41 % with a short-circuit current density of 8.41 mA cm⁻², open-circuit voltage of 748.3 mV and a high fill factor of 70.16 % under the simulated light of 100 mW cm⁻² with AM 1.5 filter. This is the first report describing the efficiency enhancement in a solid-state dye sensitized solar cell based on a solid polymer electrolyte incorporating a binary cation iodide salt and TiO₂ nanofiller and a photoanode co-sensitized with PbS/CdS quantum dots and N719 dye demonstrating the cumulative effect by the mixed cation effect and co-sensitization.

由于能量转换过程能够吸收来自广泛范围的太阳光谱（包括可见光和近红外区域）的光子，因此能量转换过程使共增感型太阳能电池受到更多关注。TiO ₂电极与PbS / CdS核-壳量子点和N719染料共敏化。PbS / CdS / N719染料敏化太阳能电池是用基于聚（环氧乙烷）的固态聚合物电解质制成的，该电解质由碘化物/三碘化物氧化还原对组成。通过加入不同尺寸阳离子的二碘盐混合物，碘化四丙铵和碘化钾，可以提高电解质的碘离子传导率。通过掺入TiO ₂进一步提高了太阳能电池的性能电解质中的P90纳米填料。最好的固态太阳能电池在模拟光为100的情况下，其短路电流密度为8.41 mA cm ^-2，开路电压为748.3 mV，填充系数为70.16％，显示出显着更高的效率，为4.41％。配备AM 1.5滤镜的mW cm ^-2。这是第一个描述固态染料敏化太阳能电池效率提高的报告，该太阳能电池基于固体聚合物电解质，该电解质包含二元碘化盐和TiO ₂纳米填料以及与PbS / CdS量子点和N719染料共敏化的光阳极通过混合阳离子效应和共敏化产生累积效应。
