太阳能转换和光诱导生物活性传感器代表了热门的科学领域，其中界面对高效应用起着决定性作用。具体调整这些界面的关键是精确了解界面结构及其在微观（最好是原子尺度）上的形成。然而，在相关的复杂化学环境中，深入了解界面反应尤其具有挑战性。这篇综述介绍了一系列具有相应界面的材料系统，这些界面对于能量转换和传感器技术的高效应用具有重要意义。它强调了能够在非真空制备和光活性研究期间原位监测关键物理化学反应的适当分析技术，包括定义明确的无机外延参考表面，掩埋界面和在化学气相环境中制备期间分析的分离外延材料的低缺陷成核。然后在气体和液体环境中对它们的表面进行改性和功能化。最后，对无机稳定光活性材料与响应性软物质之间更为复杂的生物活性耦合进行了综述。界面形成、结构和/或人工光化学界面反应在真实的时间中被仔细检查到原子尺度，还解释了平衡与非平衡、动力学驱动的过程，以加速实现高效能源材料和利用界面处的光诱导过程的进展。
Solar energy conversion and photoinduced bioactive sensors are representing topical scientific fields, where interfaces play a decisive role for efficient applications. The key to specifically tune these interfaces is a precise knowledge of interfacial structures and their formation on the microscopic, preferably atomic scale. Gaining thorough insight into interfacial reactions, however, is particularly challenging in relevant complex chemical environment. This review introduces a spectrum of material systems with corresponding interfaces significant for efficient applications in energy conversion and sensor technologies. It highlights appropriate analysis techniques capable of monitoring critical physicochemical reactions in situ during non‐vacuum preparation and photoactivity studies including well‐defined inorganic epitaxial reference surfaces, buried interfaces, and low‐defect nucleation of disjunct epitaxial materials that are analyzed during preparation in chemical vapor environment. Their surfaces are then modified and functionalized in gaseous and liquid environment. Finally, even more complex coupling of inorganic stable photoactive materials with responsive soft matter for bioactivity is reviewed. Interface formation, structure, and/or artificial photochemical interfacial reactions are scrutinized down to the atomic scale in real time, also accounting for equilibrium versus non‐equilibrium, kinetically driven processes, in order to accelerate progresses in the realization of efficient energy materials and in the exploitation of photoinduced processes at interfaces.
