Tin-zinc-oxide nanocomposites (SZO) as promising electron transport layers for efficient and stable perovskite solar cells.

ABSTRACT: Tin-zinc-oxide nanocomposites (SZO) with various Sn : Zn ratios were successfully fabricated and tested as electron transport layers (ETLs) in perovskite solar cells (PVSCs). The fabricated nanocomposites showed good crystallinity, good contact between layers, good electrical conductivity, and favorable light absorption, resulting in an enhancement in the net efficiency of CH₃NH₃PbI₃ (MAPI)-based perovskite solar cells. The device made of SZO-Sn_0.05 as an ETL showed a maximum power conversion efficiency (PCE) of 17.81% with a short-circuit current density (J _sc) of 23.59 mA cm^-2, an open-circuit voltage (V _oc) of 1 V, and a fill factor (FF) of 0.754. However, the ETL containing lower Sn ratios showed
