The Internet of Things revolution requires a low-cost, stable, and highly efficient power source to allow autonomous operation smart objects wireless sensors even at very low light levels. Indoor photovoltaics (PV) has the potential fulfil these requirements, providing independence from main grid, portability, improved sustainability for low-consumption devices. Whereas polycrystalline silicon dominates outdoor solar cell market, amorphous is commercially more suited products used inside buildings, delivering higher efficiencies under indoor illumination (with its extremely lower intensities narrower spectra compared sunlight). In recent years, there been remarkable rise in research development new generation photovoltaic cells, i.e., those based on organic, dye-sensitized perovskite absorbers, focused applications with rising well above possible sun reaching surpassing 30 % conversion efficiency threshold. This review provides systematic overview PV devices, highlighting progress achieved strategies design cells as issues be resolved this field continue prosper. We also analyse differences device meant outdoors vs indoors. Markets tapped by harvesting are huge, ranging building-integrated elements consumer products, biomedical communication technologies.

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.

Abstract Dye‐sensitized solar cell (DSSC) represents an emerging technology in the field of photovoltaics, achieving impressive efficiency 36.27% with a tandem structure to date. This performance underscores potential DSSC rival commercially established conventional silicon cells future. However, development hinges on selection suitable materials, particularly for photoanode layer. Challenges arise from non‐ideal interfaces resulting inefficient material choices, which hinder effective charge transport and stability. Given that light harvesting primarily occurs at photoanode, it is crucial understand both fundamental contemporary research methodologies anchoring dye molecules prevent unwanted electron recombination. review focuses progress selecting materials associated strategies. It examines metal oxide semiconductors, explores 2D conductive polymer metal‐organic frameworks cells, determining their effectiveness compared other enhancing efficiency.

Carbon black (CB) is a readily available, inexpensive carbonaceous material with good catalytic activity, which has been utilized alone or in composites to fabricate highly efficient counter electrodes (CEs) for dye-sensitized solar cells (DSSCs) employing copper redox couple. First, the activities of CEs various CB layers were evaluated and results reveal that number an important factor determining electrochemical behaviors CEs. At optimal layers, CE electrocatalytic activity higher than Pt power conversion efficiency (PCE) corresponding DSSC (8.58%) sensitized by Y123 also cell using (6.89%). To further increase performance CEs, poly(3,4-ethylenedioxythiophene) (PEDOT) film deposited on CB/FTO forming PEDOT/CB/FTO composite It shows have even plain CB, PEDOT, ones. By these PCE 10.08% can be achieved. Under room light conditions, achieve high 26.21% (1500 lux). The stability.

Despite significant progress in device performance, dye-sensitized solar cells (DSSCs) continue to fall short of their theoretical potential. Moreover, research recent years needs pay more attention improving the fabrication process. To achieve efficiency limit, it is crucial optimize interface between dye and TiO2 nanoparticles entire stack. Our study indicates that optimizing structure or size coadsorbents implementing a monolayer adsorption process can be an effective strategy reduce charge recombination enhance light-harvesting properties. aims develop surface-coating adsorbent plan controls nanoparticle radiative limit power conversion (PCE). Specifically, we utilized 2-thiophenecarboxylic acid (THCA) chenodeoxycholic (CDCA) as postinterfacial adsorbents. results demonstrate this approach effectively achieves desired PCE limit. Combined with coadsorbent engineering optimization, increased packing area on nanoparticles' surface, reaching improved over 13.17% under simulated sunlight (1.5G), which highest porphyrin single dye-based DSSC. In particular, practical was also applied large-area DSSC 3 cm2, yielding remarkable 9.04%.
