Aqueous dye-sensitized solar cells (a-DSSCs) have emerged as a promising option for safe, cost-effective, and environmentally friendly photovoltaic technology. Unlike conventional organic-based DSSCs, a-DSSCs utilize water greener safer electrolyte solvent. This study introduces the first time use of N-methylbenzimidazolium acetate (HNMBI+OAc–) along with water-soluble copper redox-couple [bis(6,6′-dimethyl-2,2′-bipyridine) (I/II) acetate] in a-DSSCs. The delves into electrochemical properties different compositions, highlighting significance employed HNMBI+OAc– additive providing free N-methylbenzimidazole Lewis base medium that turn enhances performance by mitigating electron recombination processes possibly improving dye regeneration. Furthermore, optimized tested exhibited remarkable stability when exposed to constant ambient light irradiations one year, or high temperatures (52 °C) 1000 h dark, marking successful progress toward sustainable durable devices.

In this work, we report the first single-step, size-controlled synthesis of Cu3VSe4 cuboidal nanocrystals, with longest dimension ranging from 9 to 36 nm, and their use in replacing platinum counter electrode dye-sensitized solar cells. Cu3VSe4, a ternary semiconductor class sulvanites, is theoretically predicted have good hole mobility, making it promising candidate for charge transport photovoltaic devices. The identity crystalline purity nanocrystals were validated by X-ray powder diffraction (XRD) Raman spectroscopy. particle size was determined XRD data using Williamson–Hall equation found agreement transmission electron microscopy imaging. Based on electrochemical activity studied cyclic voltammetry, nanomaterials further employed fabricating electrodes (CEs) Pt-free prepared as thin films, transfer kinetics impedance work demonstrates that successfully replace DSSCs. CEs fabricated having an average 31.6 nm outperformed Pt, leading DSSCs highest power conversion efficiency (5.93%) when compared those Pt CE (5.85%).

Dye‐sensitized solar cells (DSSCs)‐integrated Li‐ion batteries (LIBs) are considered a promising solution as wireless power source for the increasing number of miniaturized portable devices and internet things (IoTs). However, DSSCs suffer from stability issues because using volatile electrolyte solvents that leak through seal. To solve this problem, in study, polymer gel based on high‐boiling solvent 3‐methoxypropionitrile (bp = 164–165 °C) is used, backside sealed by hot press surlyn Al foil. A highly stable efficient counter electrode, Pt/porous carbon (Pt/PC), also used to fabricate devices, which show high PCE 25.7%–29.4% under illumination 500–2000 lux. The fabricated DSSC shows outstanding room condition operating at 50 °C. mini‐module 13.3 cm 2 , 22.9–23.3%, P max 166.4–643.0 μW can recharge LIB while powering an IoT device producing output greater than consumes. store charge be when light cut off, indicating reliability photocharging devices.
