Enhancing the performance of perovskite solar cells (PSCs) is one of the prime concerns of researchers worldwide. For PSC devices, it is essential to develop the individual layer efficiently and cost-effectively. This work emphasizes the possibility of employing Zn-Sn oxide-based composite materials as an alternative electron transport layer (ETL) in PSC devices. Pristine Zn SnO (ZTO), composite ZTO-ZnO, and ZTO-SnO heterostructure-based ETL were prepared by simple solid-state calcination technique and proposed as an alternative for the TiO photoanode used in the PSC devices. The power conversion efficiency of the designed PSC was studied based on crystallinity, morphology, cross-section, roughness, contact angle, work function, and Raman analysis of the ETL material. TEM analysis confirms the phase pure ZTO and heterostructure formation as a function of material stoichiometry. Compared to the pristine ZTO, the ZTO-ZnO and ZTO-SnO composites have an enhanced PSC performance. The ZTO-SnO composites exhibit better band matching and charge transfer behavior with the perovskite layer than the pristine ZTO and ZTO-ZnO composites. ZTO-SnO ETL-based PSC device displays a maximum efficiency of 15.6 %, while ZTO-ZnO shows a maximum efficiency of 13.1 %, which is more than 10.5 % for the pristine ZTO. The results indicate that Zn SnO -based composites can be suitable for ETL in PSC device fabrication.

“…[20,21] Worse off, the presence of water vapor in the air could accelerate the phase change, resulting in a shorter lifetime. [22,23] Many attempts have been made to resolve this challenge, including interface engineering, strain engineering, doping, and encapsulation etc. [18,21,24] For example, DMAI and the derivative have been widely adopted as an additive for the high performance of CsPbI 3 solar cells, which slightly enhanced the stability of such devices, due possibly to the tensile strain caused by the oversized DMA þ ions in the A site.…”

Hindered Phase Transition Kinetics of α‐CsPbI₃ by External Tension

Recently, the all‐inorganic perovskite solar cells have attracted large amount of attention, due to the much better water resistance compared to the organic counterparts. Unfortunately, the undesired phase transition remained a significant challenge, despite the many attempts. An important step forward has been made here by numerical simulation, which discovered the significance of external strain to the stability of desired α‐CsPbI3, whose lifetime can be extended up to 3 times by non‐hydrostatic tension, as has been verified by both modelling and experimental results. In addition, such lifetime could be even enhanced further by hydrostatic tension, as indicated by the simulation. The unexpected observation provided not only an effective method to extend the lifetime of the perovskite devices, but also opened an unexpected path for the wide research community to utilise the straining engineering method that has been extensively investigated in the perovskite research.This article is protected by copyright.
