In recent years, the power conversion efficiency (PCE (%)) of perovskite solar cells (PSCs) has improved to over 26%. To enhance the photovoltaic properties of PSCs, several materials for the electron transport layer (ETL) have been investigated. Zinc oxide (ZnO) is a significant ETL due to its high electron mobility and optical transparency in PSCs. As a result of various deposition methods, ZnO ETL can be processed at low temperatures. On the other hand, based on several studies, metal-doped ZnO can facilitate electron transfer, thereby improving the performance of un-doped ZnO ETL-based PSCs. Here, to improve the PCE (%) and long-term stability of un-doped ZnO ETL-PSCs, silver (Ag)-doped ZnO 1wt% as a buffer layer is examined. In this paper, with the addition of an organic solvent (ethanol) to the dispersion of Ag-doped ZnO 1 wt% nanoparticles (NPs) in deionized (DI) water, the morphology of the buffer layer (Ag-doped ZnO 1 wt%) can be controlled. This approach focuses on reducing the wettability of the ZnO/Ag-doped ZnO 1 wt% bilayer ETLs and enhancing the stability of un-doped ZnO ETL-PSCs. According to the results, the ZnO/H2O-ethanol mixtures-Ag-doped ZnO 1 wt% bilayer ETL leads to the formation of high-quality perovskite with low defects, reducing the recombination rate, and long-term stability of un-doped ZnO ETL-PSCs in ambient conditions.

“…This bilayer also had the lowest reduction in PCE (device degradation) as a function of time, highlighting the importance of ZnO in improving the device stability by suppressing the chemical reactions at the ETLperovskite interface. 180 It has been reported that the morphology of ZnO also plays a significant role in improving the PCE efficiency, and ZnO nanoparticles exhibit better efficiencies than nanorods as the 1D structures provide direct electron pathways for electron transport. 181 The electrons suffer several trapping and detrapping events, especially at the grain boundaries of nanoparticles.…”

“…Such devices have employed ZnO in sensitizers in various configurations, most notably in dye-sensitized solar cells (DSSCs), quantum-dot sensitized solar cells (QDSSCs), and perovskite-sensitized solar cells (PSSCs or PSCs). In DSSCs, the most common sensitizers are Phyto-dye extracts and derived complexes which, under monochromatic light, gave photo conversion efficiencies above 2% [60]. However, the role of ZnO was often limited under certain operating conditions when used jointly with other complexes in contrast to TiO 2 , which appeared to function more effectively due to its lower alkalinity.…”

“…It is now widely accepted that the control of these parameters can be exerted gainfully through the synthesis and device fabrication method. Amongst the most impactful control pathways are the oxide nanostructure and engineering of the interface [56,[58][59][60], the deposition method, posttreatment such as thermal decomposition [60], and doping [61][62][63][67][68][69]. The first reported application of ZnO as an electron transporting layer (ETL) for PSCs was by Kumar et al [70].…”

Zinc oxide (ZnO) has been widely studied over the last decade for its remarkable properties in optoelectronic and photovoltaic devices because of its high electron mobility and excitonic properties, probably the broadest range of nanostructured forms, and their ease and low cost of synthesis by a wide variety of methods. The volume of recent work on ZnO nanostructures and their devices can potentially overshadow significant developments in the field. Therefore, there is a need for a concise description of the most recent advances in the field. In this review, we focus on the effect of ZnO nanostructure morphologies on the performance of ZnO-based solar cells sensitized using methylammonium lead iodide perovskite. We present an exhaustive discussion of the synthesis routes for different ZnO nanostructure morphologies, ways to control the morphology, and the impact of morphology on the photo-conversion efficiency of a given PSC.
