Organic inorganic halide perovskites have drawn great attention in the past decade, due to their superior photovoltaic performance with an efficiency over 25%. For planar heterojunction structure perovskite solar cells (PSCs) tin oxide based electron transport layers (ETLs) have become one of the most suitable candidates to replace titanium oxide to make flexible devices because of their low‐temperature processing. The deposition techniques of SnO2 can be categorized into chemical deposition, such as sol‐gel, chemical bathing or atomic layer deposition, and physical deposition, such as thermal evaporation or sputtering. Depending on the deposition technique, defects, and morphology in the SnO2 layer may vary drastically, leading to poor performance of PSCs. In this review, we have provided a comprehensive picture of the recent progress and challenges of different SnO2 ETL deposition techniques and the performance of PSC devices. The additional modifications on SnO2 mentioned in this article are also effective ways to eliminate the intrinsic defects in the film. The drawbacks and benefits of SnO2 ETLs and the corresponding actions for this are also discussed. We hope this review will help with the comprehensive understanding of the relationship between the property of SnO2 and its structure of ETLs to enhance PSCs' performance.

“…[ 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 ] Therefore, considerable research has been devoted to improving the PSC performance via ETL modification. [ 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 ] SnO 2 nanocrystals are a widely used ETL material that can be oriented so as to facilitate the vertical growth of the perovskite crystals, a morphology essential to charge carrier transport. In addition, a suitable structural modification of the SnO 2 ETL can result in an enhanced ETL‐perovskite interfacial contact as well as increased pack densification and grain size of the perovskite crystals, which, in turn, increase the fill factor (FF) and stability of the PSC devices.…”

The electron transport layer (ETL) is a key component of regular perovskite solar cells to promote the overall charge extraction efficiency and tune the crystallinity of the perovskite layer for better device performance. The authors present a novel protocol of ETL engineering by incorporating a composition of the perovskite precursor, methylammonium chloride (MACl), or formamidine chloride (FACl), into SnO 2 layers, which are then converted into the crystal nuclei of perovskites by reaction with PbI 2 . The SnO 2 -embedded nuclei remarkably improve the morphology and crystallinity of the optically active perovskite layers. The improved ETL-to-perovskite electrical contact and dense packing of large-grained perovskites enhance the carrier mobility and suppress charge recombination. The power conversion efficiency increases from 20.12% (blank device) to 21.87% (21.72%) for devices with MACl (FACl) as an ETL dopant. Moreover, all the precursor-engineered cells exhibit a record-high fill factor (82%).

Fluorine and indium elements in F-doped SnO 2 (FTO) and Sndoped In 2 O 3 (ITO), respectively, significantly contribute toward enhancing the electrical conductivity of these transparent conductive oxides. In this study, fluorine was combined with indium to modify the SnO 2 electron transport layer (ETL) through InF 3 . Consequently, the modified perovskite solar cells (PSCs) showe the favorable alignment of energy levels, improved absorption and utilization of light, enhanced interfacial charge extraction, and suppressed interfacial charge recombination. After InF 3 modification, the open circuit voltage (V oc ) and fill factor (FF) of the PSC were significantly improved, and the photoelectric conversion efficiency (PCE) reached 21.39 %, far exceeding that of the control PSC (19.62 %).
