Compared to nature's photoelectric conversion processes, artificial devices are still far inferior in efficiency and stability. Inspired by light absorption and resonance energy transfer processes of chlorophyll, we developed a highly efficient photoelectric conversion system by introducing Carbon quantum dots (CQDs) as an electron transfer intermediary. Compared with conventional dye-sensitized semiconductor systems, the present CQD-doped system showed significantly higher photoelectric conversion efficiency, as much as 7 times that without CQDs. The CQD-doped dye/semiconductor system may provide a powerful approach to the development of highly efficient photoelectric devices.
与自然界的光电转换过程相比，人工器件在效率和稳定性方面仍有很大差距。受叶绿素光吸收和共振能量转移过程的启发，我们通过引入碳量子点 (CQDs) 作为电子转移中间体，开发了一种高效的光电转换系统。与传统的染料敏化半导体体系相比，该 CQD 掺杂体系的光电转换效率显著提高，最高可达无 CQD 时的 7 倍。CQD 掺杂的染料/半导体体系为高效光电器件的发展提供了一种有力途径。
