A simple photovoltaically self‐charging energy‐storage system (PSESS) has been fabricated as an effective solar energy‐storage power cell. The PSESS is capable of the in situ storage of visible light energy in the form of electrical energy. The PSESS is assembled on a photoelectrode (fluorine‐doped tin oxide) that contained a dye‐sensitized and hole‐trapping phenosafranine–polyvinylpyrrolidone film in association with an electroactive and highly dielectric chlorochalcone–polyvinylidene fluoride (PVDF) film, in which photogenerated electrons are stored. Here, chlorochalcone particles act as a catalytic agent for electroactive β crystal nucleation, visible‐light emission, and the improved dielectric value of the composite thin films. A proportion of 85 % electroactive β phase nucleation and a high dielectric constant (≈60) are achieved by incorporating 20 mass % chlorochalcone in PVDF. The self‐charging capability of the PSESS was verified under a light illumination intensity of 110 mW cm−2. The PSESS was charged up to 0.95 V under light illumination. Moreover, the device wass discharged with a constant current density 1.25 mA g−1 for a long time (≈560 min) after the light was switched off. The photogenerated energy and charge density of the PSESS are approximately 5.25 mWh g−1 and 42 C g−1, respectively. The maximum capacitance attained under the light illumination is approximately 44 F g−1, which is many times greater than two‐electrode self‐charged photovoltaic cells reported previously. A blue light‐emitting diode can be driven by using the PSESSs as a power bank.

Photopowered energy systems (PPESs), which simultaneously achieve power conversion and energy storage, are one of the most promising auxiliaries to fulfill the giant and diversified power demand in modern society. Devices with a low cost, wearable, compact structure and the potential to add a variety of features (such as photochromic, flexible, textile, and wearable) have received extensive research attention. Photo‐supercapacitors are becoming one of the most extensively researched PPESs due to their ease of fabrication, mitigation of solar irradiation discontinuities, and the promotion of renewable energy utilization, and these devices have been fabricated with different combinations of photovoltage devices and energy‐storage technologies. This review summarizes the development of photo‐supercapacitors that integrate third‐generation solar cells and supercapacitors, with a focus on materials alignment, performance, structure design, and application. Finally, current challenges, possible solutions, and future perspectives are discussed.

“…In other words, external electrical wires with internal resistance will consume part of the power, resulting in the decrease of ESE. Most importantly, traditional energy conversion and storage systems are both large and bulky, and thus, can no longer meet the demands of portable and wearable electronic devices . Therefore, to solve the above‐mentioned problems, a new device with the dual function of photoelectric conversion (PC) and energy storage (ES) came into being.…”

Although solar cell technology is an effective way to realize the utilization of solar energy, the output power of solar cells cannot be continuous and stable, due to the intermittent nature of the sunlight. Therefore, proper energy storage devices are generally required to store the generated energy of solar cells. Photo‐supercapacitor is a new energy device that combines the photoelectric conversion function of a solar cell with the energy storage capability of a supercapacitor. This dual‐functionality is the main reason why photo‐supercapacitors are receiving more and more interest for their potential applications in future portable and wearable devices. This review presents the development history and the representative research progress of various photo‐supercapacitors, as well as the problems and challenges that still need to be addressed for the construction of better photo‐supercapacitors. Finally, suggestions for future research directions and opportunities in this fascinating field are given.
