“…The carrier density calculation using the slope of the fitted linear part in the plots results in a high value of 4−7 × 10 20 cm −3 , which is related to a high concentration of defects in the NPs. 61 From the EDS as a qualitative and a semiquantitative analysis, peaks related to the Cu, Sn, S, C, N, and O elements could be observed in the spectra (Figure S5). The atomic ratios of Cu/Sn and S/Cu are about 1.8 and 1.5, respectively, which show a Sn-rich composition for both CTS NPs, while they have a similar composition.…”

“…The negative slope of the linear fit in the Mott–Schottky plots in Figure f indicates that both CTS NPs have a p-type conduction. The carrier density calculation using the slope of the fitted linear part in the plots results in a high value of 4–7 × 10 20 cm –3 , which is related to a high concentration of defects in the NPs …”

We investigate the use of simple nontoxic Cu 2 SnS 3 (CTS) nanoparticles (NPs) as low-cost dopant-free hole-transport materials (HTMs) a substitute for spiro-OMeTAD in an n-ip mesoscopic architecture of perovskite solar cells (PSCs). Besides, this work confirms the critical role of the crystalline phase of CTS NPs on the performance of the device. Using a facile one-pot heating-up procedure, pure zincblende and wurtzite structures of CTS NPs were obtained by sulfur element and thiourea as the sulfur source, respectively, and were dispersed in chloroform to make very stable nonpolar ink that is compatible with the perovskite. Nanoparticles with the wurtzite crystal phase showed much better photovoltaic performance compared to the zincblende phase with efficiencies of 13.01 and 7.87%, respectively. The efficiency of the reference solar cell using spiro-OMeTAD was 16.01%. Results from impedance spectroscopy and external quantum efficiency show that by switching from wurtzite-CTS to zincblende-CTS, the resistance of charge transfer at the perovskite/HTM interface is increased, which matches with the descending trend of fill factor of the corresponding cells. According to the morphological characteristics and electrical properties of HTM layers, the better performance of wurtzite-CTS in comparison with zincblende-CTS is due to two factors: (i) enhancement of the band-gap energy and alignment of the valance band maximum; and (ii) uniform smooth coverage of the perovskite film by monodispersed wurtzite-CTS NPs.

“…With the challenging issues of energy insecurity and environmental destruction, the astonishing growth of solar cells owing to their eco-friendly and sustainable features, has attracted interest in the growing demand for clean energy. [5][6][7] FDSSCs are an exciting innovation mainly due to tremendous features over the basic DSSC and Si-based modules, including reduced manufacturing cost, ease of processing, functionality, reasonable electrical efficiency, and other aspects. [8][9][10][11][12][13][14] In a typical DSSC, along with the working electrode (WE) and a redox electrolyte, the counter electrode (CE) also plays a crucial role in determining the overall cell power conversion efficiency.…”

“…Nanosized metal chalcogenide semiconductors show quantum confinement effects by means of shape and size control. The properties of the nanosized particles can be tuned by varying their chemical composition. − Nanostructures of various materials show excellent behavior in applications such as photodetection, photocatalysis, electrocatalysis, energy storage anodes, , electrochemical N 2 reduction, and so forth. Amid several inorganic nanoparticles (NPs), CuInS 2 (CIS) has received importance due to its low toxicity owing to the absence of lead and cadmium.…”

A simple hydrothermal route is employed to synthesize pure copper indium disulfide (CIS) and CIS nanoparticles (NPs) mediated by various natural plant extracts. The plant extracts used to mediate are Azadirachta indica (neem), Ocimum sanctum (basil), Cocos nucifera (coconut), Aloe vera (aloe), and Curcuma longa (turmeric). The tetragonal unit cell structure of as-synthesized NPs is confirmed by X-ray diffraction. The analysis by energy-dispersive X-rays shows that all the samples are nearstoichiometric. The morphologies of the NPs are confirmed by high-resolution scanning and transmission modes of electron microscopy. The thermal stability of the synthesized NPs is determined by thermogravimetric analysis. The optical energy band gap is determined from the absorption spectra using Tauc's equation. The antimicrobial activity analysis and the estimation of the minimum inhibitory concentration (MIC) value of the samples are performed for Escherichia coli, Pseudomonas aeruginosa, Proteus vulgaris, Enterobacter aerogenes, and Staphylococcus aureus pathogens. It shows that the aloe-mediated CIS NPs possess a broad inhibitory spectrum. The best inhibitory effect is observed against S. aureus, whereas the least effect was exhibited against P. vulgaris. The least MIC value is found for aloe-mediated CIS NPs (0.300 mg/mL) against S. aureus, P. aeruginosa, and E. aerogenes, along with basil-mediated NPs against E. coli. The antioxidant activity study showed that the IC 50 value to inhibit the scavenging activity is maximum for the control (vitamin C) and minimum for pure CIS NPs. The in vivo cytotoxicity study using brine shrimp eggs shows that the pure CIS NPs are more lethal to brine shrimp than the natural extract-mediated CIS NPs. The in vitro cytotoxicity study using the human lung carcinoma cell line (A549) shows that the IC 50 value of turmeric extract-mediated CIS NPs is minimum (15.62 ± 1.58 μg/mL). This observation reveals that turmeric extract-mediated CIS NPs are the most potent in terms of cytotoxicity toward the A549 cell line.
