Biomass-derived carbon electrodes for supercapacitors and hybrid solar cells: towards sustainable photo-supercapacitors

Abstract

Due to their outstanding electrochemical properties, electrical conductivity, flexibility, and low-cost, carbon materials open up new opportunities for the design of compact devices with a wide variety of potential applications....

Advances in Carbon Materials Applied to Carbon‐Based Perovskite Solar Cells

“…The use of renewable resources to obtain carbon materials from biomass for application in solar cells has been increasing in recent years due to their wide availability, low‐cost processability, and high performance. [ 186 ] The great demand for the use of carbon has prompted researchers to seek more effective alternatives to obtain it in an ultralow‐cost procedure, which is also a “recyclable waste.” Thus, biocarbon produced by the pyrolysis of biomass has been emphasized. Different sources of biomass to obtain carbon have been used and applied to C–PSCs, such as aloe vera, brewery residues, soybean dreg residues, cellulose, corn stalk, peanut shell, Phragmites australis, and bamboo chopsticks.…”

Physicochemical Modeling of Electrochemical Impedance in Solid-State Supercapacitors

“…The garlic peels were then placed in a 23 mL autoclave bomb reaction vessel and chemically treated with 5% aqueous MgSO 4 (Acros Organics, Geel, Belgium) solution (10 mL). Here, MgSO 4 was used as an activating agent to enlarge existing pores and allow the formation of new pores by opening the inaccessible pores, thereby preventing ash formation [ 40 ]. The reaction was hydrothermally treated for 12 h at 230 °C.…”

Systematic arrangement control of functional organic molecules

“…Functional organic molecules with tunable properties are composed of earth-abundant and readily available building blocks (C, H, O, N, and S). 1 One of the typical examples is π-conjugated molecules, which exhibit luminescence and conductivity owing to their interaction with light [2][3][4][5][6][7][8] and their electron transport capabilities, [9][10][11][12][13][14][15][16] respectively. As a result, they are expected to play an important role in a variety of research fields, including electroluminescence, 2,6-8 photovoltaics, 9,10 electronics, 11 and energy production and storage.…”
