1 Introduction Interfacial phenomena play an essential role in operating devices with layered structures, such as solar cells,[1-3] molecular electronic devices,[4-6] and energy storage/harvesting devices,[7-10] which possess electrochemical and electronic interfaces. Therefore, optimal interface engineering techniques for layered devices have been developed based on a comprehensive understanding of interfacial phenomena.

With the rapid increase in the number of wearable devices and the expansion of the Internet of Things (IoT), there is a growing emphasis on the importance of on-chip energy storage units. On-chip energy sources are essential components in self-powered autonomous systems and must meet the power requirements of compact and advanced electronic devices.
