Properties of Perovskite Solar Cells by the Sputtered Compact TiO₂ Layer

Effect of UV-Light Treatment on Efficiency of Perovskite Solar Cells (PSCs)

“…Figure 4a (100 nm) were sequentially stacked on the substrate as shown in Figure 4b. The thickness of the layers was consistent with the configuration previously reported in a similar fabrication procedure [20].…”

“…The TiO 2 paste was prepared with TiO 2 powder (anatase < 25 nm, 99.7%, Sigma-Aldrich). Second, CH 3 NH 3 PbI 3 was formed during the spin-coating process with CH 3 NH 3 I and PbI 2 solutions, according to a previous study [20]. Finally, a spiro-MeOTAD solution was dissolved in a mixture of chlorobenzene, 4-tert-butyl pyridine and lithium bis(trifluoromethanesulfonyl)imide (Li-TFSI) (520 mg LI-TSFI in 1 ml acetonitrile, Sigma-Aldrich) and used without any additional processing.…”

Advanced Applications of Atomic Layer Deposition in Perovskite‐Based Solar Cells

“…Simultaneously, the layer can prevent the holes in the perovskite or HTL from reaching the anode. Several methods, such as spin coating, [ 39 ] sputtering, [ 40 ] and spray pyrolysis, have been used to prepare compact layers. However, the spin coating cannot produce high‐quality films, and thermal methods are not compatible with commonly used substrates.…”

Rapid Growth of TiO2 Nanoflowers via Low-Temperature Solution Process: Photovoltaic and Sensing Applications

“…have been regarded as some of the most important multi-functional materials because of their excellent functionalities and applications, such as electrochemical, photocatalytic, photo electrochemical, electronics, sensing, and so on [ 1 , 2 , 3 , 4 , 5 ]. Among various metal oxides, TiO 2 nanostructures possess a special place because of their excellent properties, such as a wide band gap, low toxicity, easy synthesis, good stability, etc., and efficient applications in lithium ion batteries, solar cells, chemo-sensors, photocatalysts, and so on [ 5 , 6 , 7 , 8 , 9 ]. TiO 2 nanostructures including nanotubes [ 10 ], nanoflakes [ 11 ], nanorods [ 12 ], solid and hollow spheres [ 13 ], and urchin-like [ 14 ] hierarchical TiO 2 structures, have already been fabricated through a variety of solution techniques.…”
