“…Figure a shows powder X-ray diffraction (XRD) patterns obtained for the AZO, ITO, and IZO films deposited on Willow Glass. For the AZO film, the intense peak at a 2θ angle of 34.3° corresponds to the (002) peak of wurtzite ZnO . The crystallinity of ITO is similarly confirmed by the presence of the peak at 2θ = 30.5°, corresponding to the (222) peak of cubic In 2 O 3 .…”

“…IZO is deposited by RF sputtering mixed metal oxide source containing In 2 O 3 and ZnO 2 (80 wt % In, 20 wt % Zn) . Similarly, AZO (1 wt % Al, 99% ZnO) films were deposited by RF sputtering of an AZO target which was prepared by mixing Al 2 O 3 and ZnO in proportion for several hours and pressed in the form of a pellet followed by a sintering process at 1000 °C for 24 h …”

“…AZO, ITO, and IZO films are deposited onto the Willow Glass by RF sputtering of mixed metal oxide sources, as reported in the literature. ,, On top of the TCO layers, a SnO 2 electron transport layer (ETL) was spin-coated from an aqueous SnO 2 nanoparticle solution, to form a charge selective contact for the PSC, following the recent report by Jiang et al The perovskite layer used for this study was a highly alloyed ABX 3 system recently reported by Saliba et al, containing FA, MA, and Cs + in the A-site, Pb 2+ in the B-site, and both I – and Br – in the X-site, with precursor solution stoichiometry of Cs 0.04 MA 0.16 FA 0.80 Pb 1.04 I 2.6 Br 0.48 , abbreviated as FAMACs. These FAMACs films have been shown to be more thermally stable than the more commonly studied MAPbI 3 .…”

For halide perovskite solar cells (PSCs) to fulfill their vast potential for combining low-cost, high efficiency, and high throughput production they must be scaled using a truly transformative method, such as roll-to-roll processing. Bringing this reality closer to fruition, the present work demonstrates flexible perovskite solar cells with 18.1% power conversion efficiency on flexible Willow Glass substrates. We highlight the importance of the transparent conductive oxide (TCO) layers on device performance by studying various TCOs. While tin-doped indium oxide (ITO) and indium zinc oxide (IZO) based PSC devices demonstrate high photovoltaic performances, aluminum-doped zinc oxide (AZO) based devices underperformed in all device parameters. Analysis of X-ray photoemission spectroscopy data shows that the stoichiometry of the perovskite film surface changes dramatically when it is fabricated on AZO, demonstrating the importance of the substrate in perovskite film formation.

Flexible and transparent applications have become an emerging technology and have shifted to the forefront of materials science research in recent years. Transparent conductive oxide films have been applied for flat panel displays, solar cells, and transparent glass coatings. However, none of them can fulfill the requirements for advanced transparent flexible devices, such as high-frequency applications. Here, we present a promising technique for transparent flexible conducting oxide heteroepitaxial films: the direct fabrication of epitaxial molybdenum-doped indium oxide (IMO) thin films on a transparent flexible muscovite substrate. An n-type epitaxial IMO film is demonstrated with a mobility of 109 cm2 V−1 s−1, a figure of merit of 0.0976 Ω−1, a resistivity of 4.5 × 10−5 Ω cm and an average optical transmittance of 81.8% in the visible regime. This heteroepitaxial system not only exhibits excellent electrical and optical performance but also shows excellent mechanical durability. Our results illustrate that this is an outstanding way to fabricate transparent and flexible conducting elements for the evolution and expansion of next-generation smart devices.
