“…Small electronic devices, such as the digital display of a pregnancy test kit, biosensors, wearable electronics, and Bluetooth-enabled devices, can be powered by the energy produced and stored in the photocapacitor. Some other applications include power grids, emergency door sensors in transport media, pulse power in communication devices, large-scale energy supply systems, and photochromic applications. − As a result, PCs can potentially replace batteries with the added benefit of substantially higher stability than standard coin cells or LIBs.…”

In response to the current trend of miniaturization of electronic devices and sensors, the complementary coupling of high-efficiency energy conversion and low-loss energy storage technologies has given rise to the development of photocapacitors (PCs), which combine energy conversion and storage in a single device. Photovoltaic systems integrated with supercapacitors offer unique light conversion and storage capabilities, resulting in improved overall efficiency over the past decade. Consequently, researchers have explored a wide range of device combinations, materials, and characterization techniques. This review provides a comprehensive overview of photocapacitors, including their configurations, operating mechanisms, manufacturing techniques, and materials, with a focus on emerging applications in small wireless devices, Internet of Things (IoT), and Internet of Everything (IoE). Furthermore, we highlight the importance of cutting-edge materials such as metal−organic frameworks (MOFs) and organic materials for supercapacitors, as well as novel materials in photovoltaics, in advancing PCs for a carbon-free, sustainable society. We also evaluate the potential development, prospects, and application scenarios of this emerging area of research.
