论文摘要
在光电合成界面上，电化学反应是由半导体光吸光器的激发电荷载体驱动的。该界面的结构和组成决定了设备的电子和电化学性能，但是在时间域和应用电位上，这种结构通常是高度动态的。我们讨论了这种动态性质的挑战，并回顾了对所涉及过程的原子理解的最新方法，该方法越来越涉及实验和计算方法的组合。与电池中的固相物相互相的形成相似，它们的忧虑可以帮助开发用于高性能光电合成器件的功能钝化层。
At photoelectrosynthetic interfaces, an electrochemical reaction is driven by excited charge-carriers from a semiconducting photoabsorber. Structure and composition of this interface determine both the electronic and electrochemical performance of devices, yet this structure is often highly dynamic both in the time-domain and upon applied potentials. We discuss the arising challenges from this dynamical nature and review recent approaches to gain an atomistic understanding of the involved processes, which increasingly involves a combination of experimental and computational methods. Bearing a similarity to solid-electrolyte interphase formation in batteries, their apprehension could help to develop functional passivation layers for high-performance photoelectrosynthetic devices.
