“…In simpler words, this shrinking bandgap is also referred to as the bandgap narrowing. [ 16 ] This narrowing effect is indicative of the replacement of the lanthanide ions in pristine SnO 2 for the Sn sites. This is possible due to the defect numbers in the lanthanides content used for doping.…”

This work for the first time develops and employs the novel cerium‐praseodymium‐neodymium oxide co‐doped tin oxide (Ln3+(Ce3+‐Pr3+‐Nd3+):SnO2) system for varied energy applications including electro‐catalytic, super‐capacitive, and photovoltaic conversion potential. The outstanding optical, compositional, crystalline, and morphological aspects of the synthesized material express its effectiveness for energy related micro‐electrochemical applications. Bandgap narrowing due to lanthanide doping and acquiring cassiterite crystalline phase results in the auspicious output. O2 and H2 evolution of the developed electro‐catalyst expresses superior energy production with lower overpotential values of 95 mV for O2 and 131 mV toward H2. Fabricated electrode expresses an impressive charge storage potential with the specific capacitance of 151.62 F g−1. Also, this electrode has an extended service life for 100 min showing its ultra‐durability for commercial applications. Ln3+(Ce3+‐Pr3+‐Nd3+):SnO2 is used as an electron transport layer in the cesium based solar cells with the power conversion efficiency of 12.49%, short circuit current of 19.63 mA cm−1, and open circuit voltage of 1.2 V under artificial sun with negligible hysteresis. Ln3+(Ce3+‐Pr3+‐Nd3+):SnO2 is an effective material with the perfect bandgap tuned exceeding the pristine material for diverse energy applications marked by profound sustainability and economic viability.

“…The nanowires can be obtained by various techniques with both chemical and physical approaches. In the last few years, many researchers have been devoted to synthesizing SnO2 nanowires using chemical vapor deposition [3][4][5][6] or physical vapor deposition. [7,8] Recently, Asha Sharma et al, reported a template directed electrodeposition to produce one-dimensional nanostructures of SnO2.…”

This paper reports a growth of tin oxide nanowires on gold patterns by chemical vapor deposition. A 90 nm gold layer was deposited on a silicon wafer using a sputtering system and pre‐pattern by lift‐off techniques. Tin oxide nanowires were selectively grown on the gold pattern by chemical vapor deposition technique with 750°C and 5 × 10‐2 torr. High resolution transmission electron microscopy measurements showed that nanowire possessed a single crystal nature with tetragonal crystal system and the calculated lattice constants (a = 0.474 nm; c = 0.318 nm) were closed to those of standard pattern of SnO2. The ready SnO2 nanowire grown on the gold patterns were investigated for electrochemical sensor development.

Transparent conducting oxides (TCOs) are a crucial component of solar cells. Tin-doped indium oxide (ITO) is the most employed TCO, but the scarcity and high price of indium induce a search for lower-cost TCOs with equivalent properties as substitutes. Tin dioxide (SnO2) films have many advantages, such as rich sources of material, low prices, and nontoxicity. SnO2 films present a high visible-light transmittance, near-infrared light reflectivity, and excellent electrical properties. They also have a higher chemical and mechanical stability compared to ITO. The aim of this work is to elaborate SnO2 films by radio frequency (RF)-magnetron sputtering in order to use them as electrodes for organic solar cells (OSCs). The SnO2 films were deposited on glass, SiO2, and quartz substrates in a mixed environment of Ar and O2. X-ray diffraction (XRD) measurements show that the as-deposited SnO2 films are polycrystalline with a cassiterite tetragonal structure. Scanning electron microscopy (SEM) analysis showed that the films are homogeneous, continuous, and nanostructured. The electrical resistivity and average optical transmittance of the samples are about 10–3 Ω.cm and over 80%, respectively. The estimated optical band gap (E g) is around 4.0 eV, while the work function (WF) of the films is around 5.0 eV. The SnO2 films are used as electrodes for inverted OSCs, using poly(3-hexylthiophene-2,5-diyl): [6,6]-phenyl-C60-butryric acid methyl ester (P3HT:PC60BM) as the active layer. The device’s open-circuit voltage (V OC) and short-circuit current density (J SC) are similar to those obtained for the inverted OSCs employing ITO as the same electrode. Even if the achieved power conversion efficiency (PCE) is lower compared to the value for the reference OSC with an ITO electrode, these results are promising and place SnO2 TCO as a potential candidate to replace ITO.
