虽然具有光电流检测功能的超快光谱在 2012 年之前几乎不为人知，但在过去 3 年中，来自不同领域的许多研究小组独立开发了超快电探针方法，并报告了有前景的试点研究。在这里，我们讨论这些最新进展，并提供我们对光电流检测如何成功克服全光学方法的许多局限性的看法，这使其成为设备光物理方面的首选技术。我们还强调了引人注目的现有问题和研究问题，并提出了进一步发展的方法，概述了在不久的将来使用光电流超快光学探针有望取得的潜在突破。
While ultrafast spectroscopy with photocurrent detection was almost unknown before 2012, in the last 3 years, a number of research groups from different fields have independently developed ultrafast electric probe approaches and reported promising pilot studies. Here, we discuss these recent advances and provide our perspective on how photocurrent detection successfully overcomes many limitations of all-optical methods, which makes it a technique of choice when device photophysics is concerned. We also highlight compelling existing problems and research questions and suggest ways for further development, outlining the potential breakthroughs to be expected in the near future using photocurrent ultrafast optical probes.
