“…The electrode materials are playing a vital role to enhance the energy density of SCs by increasing its operating potential window. The electrode materials of SCs should possess high catalytic activity, excellent electrical conductivity, extraordinary surface area, exclusive porous architecture, outstanding mechanical stability, and low production cost . Moreover, the fabrication of asymmetric SCs (ASCs) has recently drawn research interest among scientists, since it can integrate battery‐type Faradic electrode as energy sources as well as a capacitor‐type electrode as power sources to enhance the energy density of the SCs .…”

To meet a fast-emerging demand, flexible energy storage applications have a great interest in the development of highly flexible hierarchical nanoarchitectures. Metal nitrides have recently been paid a significant interest as a promising electrode material for supercapacitors (SCs) owing to their high electrical conductivity, excellent redox properties, and outstanding mechanical strength. However, poor electrochemical stability seriously limits the commercialization possibilities. Herein, a novel strategy is presented for the synthesis of nitrogen-doped graphene encapsulated with ultrasmall nickelcobalt nitride (NiCo 2 N) and nickel-iron nitride (NiFeN) core-shell architectures that are explored as advanced electrodes for flexible solid-state SC. The flexible NiCo 2 N@NG//NiFeN@NG asymmetric SC delivers an ultrahigh energy density of ≈94.93 Wh kg −1 at 0.79 kW kg −1 , exceptional power density (≈74.67 Wh kg −1 at 39.53 kW kg −1 ), and ultralong cycle life (≈5.07% drop in initial capacity after 25 000 cycles). These results promote the core-shell hybrids that can be served as advanced supercapacitor materials for flexible energy storage applications.

“…Taking advantage of the bandgap tunability for perovskite materials, the open‐circuit voltage V oc for PSCs can reach over 1.0 V, which is suitable for high voltage photocapacitors. [ 42,43 ] Over the past several years, PSCs gradually became a competitive solar energy harvesting candidate in photocapacitors.…”

“…PEDOT and carbon materials not only possess charge storage function in supercapacitors based on EDL capacitance or pseudocapacitance but also are employed in PSCs as carriers transporting layers. [ 42,44 ] Similar to DS‐photocapacitors, PEDOT or carbon materials were widely used as common electrode in PSCs based photocapacitors. As an example, a PEDOT‐carbon electrode was demonstrated to bridge the supercapacitor part and the perovskite solar cell part.…”

Solar energy is one of the most abundant renewable energy sources. For efficient utilization of solar energy, photovoltaic technology is regarded as the most important source. However, due to the intermittent and unstable characteristics of solar radiation, photoelectric conversion (PC) devices fail to meet the requirements of continuous power output. With the development of rechargeable electric energy storage systems (ESSs) (e.g., supercapacitors and batteries), the integration of a PC device and a rechargeable ESS has become a promising approach to solving this problem. The so‐called integrated photorechargeable ESSs which can directly store sunlight generated electricity in daylight and reversibly release it at night time, has a huge potential for future applications. This review summarizes the development of several types of mainstream integrated photorechargeable ESSs and introduces different working mechanisms for each photorechargeable ESS in detail. Several general perspectives on challenges and future development in the field are also provided.

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.
