“…If the distance between the nozzle and the hot plate is small the droplet marks on the surface is seen, with poor adhesion and many pinholes. The desired deposition regime lies between these two extremes [40,41]. The optimum situation for CIS deposition was rate of 2 ml min −1 , 20 cm height and 350 °C deposition temperature.…”

Superstrate configuration CuInS2 (CIS) solar cells are fabricated using a spray pyrolysis method. We avoided selenization process, cyanide etching and CdS buffer layer, to keep the process ‘green’. CIS layers are formed by spray pyrolysis of an aqueous precursor ink containing metal chloride salts and thiourea at 350 °C. We investigated the effect of intentional Zn doping on structural, morphological and photovoltaic response of the fabricated CIS films by dissolving ZnCl2 in aqueous precursor solution. At a zinc doping level ranging between 0.25 and 1.00 mol%, Zn doping is found to improve the CIS crystal growth and surface morphology of CIS films. Compared with the performance of the non-doped CIS cell, the Zn-doped CIS solar cell displayed a remarkable efficiency enhancement of 58–97% and the maximum enhancement was obtained at a Zn content of 0.5 mol%. The device structure consists of and show promising PCE of 4.29 % without any anti-reflection coating. Over the course of 300 d under ambient condition, the fabricated device showed only 1% loss in efficiency.

“…These cells are composed of FTO/TiO 2 /In 2 S 3 /CIS/carbon, where all the layers are compact films (no nanostructured layer is included). Conversion efficiencies reach values close to 3% with CIS inks synthesized using a hot injection process, up to 5.2% for CIS inks deposited by spin coating and 2.67% when all the layers are deposited by spin coating of molecular precursor inks …”

“…At the same time, ZnO has also been extensively employed as n‐type semiconductor or window layer both in inorganic and hybrid solar cells . Although these materials are mainly prepared using high vacuum techniques, solar cells built with solution‐based methods that combine chalcopyrites and ZnO are not uncommon, and their efficiency has been increasing steadily over the last years . Various deposition methodologies have been used, such as electrodeposition, spraying and solution growth techniques .…”

Solar cells are prepared combining ZnO as n‐type window In2S3 as buffer layer and CuInS2 as p‐type absorbing layer. Superstrate configuration is chosen so that all the materials could be prepared using inexpensive and eco‐friendly techniques, based on solution processed deposition methods and non‐toxic materials, avoiding vacuum high temperature Cd‐containing layers and KCN purification stages. Also, no further sulfurization treatment is involved in the preparation. To improve the collection efficiency, the cells are built using two different ZnO nanostructures (with and without Cl‐doping) and compared to the response of a cell prepared with just one dense ZnO layer. The photoresponse of the three different solar cells is analysed by J–V curves under illumination and intensity‐modulated photovoltage/photocurrent spectroscopy. A systematic characterization of the morphology and composition is carried out using X‐ray diffraction Raman confocal and electronic microscopy. The introduction of a nanostructured layer is not enough to produce a marked improvement in any of the electrical parameters. Instead, the presence of Cl‐doped nanopillars is shown to increase the efficiency of the solar cells up to a maximum value of 2.8%. A better series resistance together with a higher value for the charge collection efficiency contributes to explain the corresponding improvement in cell efficiency.

“…CIS belongs to the I–III–VI 2 group having a tetragonal structure and possesses a direct band gap of ∼1.5 eV when in the bulk form . The CIS NPs find applications in numerous fields including photovoltaic devices, , light-emitting diodes, , photocatalysis, , bioimaging, , and so forth. Since NPs possess a larger surface-to-volume ratio than the bulk, they efficiently interact with tissues to provide a large number of active sites, resulting in effective biological activities …”

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.
