Abstract

Electron transfer at a donor–acceptor quantum dot–metal oxide interface is a process fundamentally relevant to solar energy conversion architectures as, e.g., sensitized solar cells and solar fuels schemes. As kinetic competition at these technologically relevant interfaces largely determines device performance, this Review surveys several aspects linking electron transfer dynamics and device efficiency; this correlation is done for systems aiming for efficiencies up to and above the ∼33% efficiency limit set by Shockley and Queisser for single gap devices. Furthermore, we critically comment on common pitfalls associated with the interpretation of kinetic data obtained from current methodologies and experimental approaches, and finally, we highlight works that, to our judgment, have contributed to a better understanding of the fundamentals governing electron transfer at quantum dot–metal oxide interfaces.

太阳能转换中量子点-金属氧化物界面的电子转移
在供体-受体量子点-金属氧化物界面上的电子转移是一个与太阳能转换架构(如敏化太阳能电池和太阳能燃料方案)基本相关的过程。由于这些技术相关接口的动态竞争在很大程度上决定了设备性能,本文综述了电子传递动力学和设备效率相关的几个方面;这种相关性适用于效率达到或高于肖克利和奎瑟为单间隙器件设定的效率限制33%的系统。此外,我们批判性地评论了与从当前方法和实验方法中获得的动力学数据解释相关的常见陷阱,最后,我们强调了根据我们的判断,有助于更好地理解量子点金属氧化物界面控制电子转移的基本原理的工作。
