“…We note that most of the metal oxide (e.g., ZnO, SnO 2 , and NiO) inks that are commercially available and used in printed optoelectronic devices also have a metal oxide solid content at around 2–2.5 wt%. In light of this, the trends observed in this work appear reasonable and somewhat consistent with the commercially available inks [ 64 , 65 , 66 , 67 ].…”

Flexible and printed perovskite solar cells (PSCs) fabricated on lightweight plastic substrates have many excellent potential applications in emerging new technologies including wearable and portable electronics, the internet of things, smart buildings, etc. To fabricate flexible and printed PSCs, all of the functional layers of devices should be processed at low temperatures. Tin oxide is one of the best metal oxide materials to employ as the electron transport layer (ETL) in PSCs. Herein, the synthesis and application of SnO2 quantum dots (QDs) to prepare the ETL of flexible and printed PSCs are demonstrated. SnO2 QDs are synthesized via a solvothermal method and processed to obtain aqueous and printable ETL ink solutions with different QD concentrations. PSCs are fabricated using a slot-die coating method on flexible plastic substrates. The solar cell performance and spectral response of the obtained devices are characterized using a solar simulator and an external quantum efficiency measurement system. The ETLs prepared using 2 wt% SnO2 QD inks are found to produce devices with a high average power conversion efficiency (PCE) along with a 10% PCE for a champion device. The results obtained in this work provide the research community with a method to prepare fully solution-processed SnO2 QD-based inks that are suitable for the deposition of SnO2 ETLs for flexible and printed PSCs.

“…However, devices based on TiO 2 show obvious J-V hysteresis and relatively poor ultraviolet (UV) stability because of its photocatalytic activity. 43 The high-temperature sintering involved in TiO 2 preparation hinders the achievement of exible devices and elevates costs. 44 In contrast, SnO 2 is recognized as a more promising ETM 45 with high light transmittance 46 originating from the wide bandgap of ∼3.6 eV 47 and electron mobility as high as ∼240 cm 2 V −1 s −1 .…”

“…Common materials used as ETL in PSCs include TiO2, ZnO and SnO 2 . However, TiO 2 suffers from the instability under UV radiation and it requires high temperatures during deposition [3]. Additionally, ZnO encounters issues with chemical residue and compatibility between ZnO and perovskite [4].…”

Tin oxide (SnO2) is frequently chosen as an electron transport layer (ETL) in perovskite solar cells (PSCs) owing to its outstanding electron transport properties. Nevertheless, the thickness of the ETL significantly influences hysteresis behavior of PCSs. To address this issue, tin (II) 2-ethylhexanoate in 2-methoxyethanol (2-MOE) was employed as the precursor solution for SnO2 ETL preparation. We systematically varied its concentrations from 0.2 M to 1.0 M to optimize the film thickness. Our findings indicate that the PSC with a SnO2 film deposited from a 0.6 M precursor concentration achieved the highest power conversion efficiency (PCE) of 13.51% and the lowest hysteresis index (HI) of 0.54. Furthermore, we explored the impact of film thickness on hysteresis behaviour and provided a comprehensive analysis. Based on the experiment, it was observed that the thickness of the film has an impact on the presence of defects and interfacial charge transfer, which could contribute to the occurrence of HI. This study offers valuable insights into the development of alternative ETLs suitable for large-scale PSC production.
