Photo‐Supercapacitors Based on Third‐Generation Solar Cells

Abstract

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.

Photo-rechargeable zinc-ion batteries

“…[1][2][3][4][5] Off-grid solar systems have been identified by the World Bank 6 as a key technology for universal electricity access, yet solar energy is intermittent, and therefore solar cells are typically connected to rechargeable batteries or capacitors. [7][8][9][10][11] This approach often requires additional electronics to match the voltage output of the energy harvester to the input voltage requirements of the energy storage units. 7,12,13 This adds to the cost and energy losses in the system.…”

Integrated Photorechargeable Energy Storage System: Next‐Generation Power Source Driving the Future

“…[ 7 ] The photorechargeable ESSs integrating PC units with rechargeable ESSs have therefore recently emerged as an attractive alternative solutions to realize energy conversion and storage in a single device. [ 8 ] These integrated photorechargeable ESSs have advantages of small volume, light‐weight, flexibility, and high‐security. [ 2,5 ] The above‐mentioned PC units can be classified into two categories: solar cells and photoelectrodes.…”

Electrochemical Characterisations to Elucidate the Pseudocapacitance Mechanisms of a CdS/WOx Nanocomposite Photoanode in Acidic Aqueous Electrolytes

“…As an extension to the concept of a solar-powered microgrid comprising battery and supercapacitor storage, researchers have begun to explore the possibility of augmenting the conversion and storage efficiencies by integrating a supercapacitor into the structure of a photovoltaic cell [18][19][20][21]. This device, known as a "photo-supercapacitor" (PS), is most commonly constructed as a monolithic three-electrode arrangement wherein the supercapacitor and solar cell share a common counter electrode located at the centre of the configuration.…”
