Dye-sensitized solar cells are moderately efficient with verified solar-to-electrical power conversion efficiencies of over 12% reported. However, even in the state-of-the-art systems only a fraction of the incident sun light is absorbed, implying substantial scope for improvement. Here we develop both state-of-the-art liquid electrolyte based DSCs and contemporary solid-state hybrid DSCs with the target being to considerably enhance the light capture and adsorption in these devices and also significantly improve the charge transport characteristics. Routes to both improve the photonic structure of the solar cells, create improved semiconducting oxide electrodes for enhanced charge transport and collection and develop and optimise new sensitizers for these systems shall be undertaken.

染料敏化太阳能电池是中等效率的，经验证的太阳能到电能的转换效率超过12%。然而，即使在最先进的系统中，也只有一小部分入射太阳光被吸收，这意味着有很大的改进空间。在这里，我们开发了最先进的基于液体电解质的DSC和当代固态混合DSC，目标是大大增强这些设备中的光捕获和吸收，并显着改善电荷传输特性。应采取既改善太阳能电池的光子结构，又创建用于增强电荷传输和收集的改进的半导体氧化物电极，并开发和优化用于这些系统的新敏化剂的路线。
