## Description

- description: Organic-inorganic perovskite solar cells (PSCs) are a promising technology
    in renewable energy due to their high efficiency and low cost. The electron transport
    layer (ETL) plays a very important role in improving device performance by minimizing
    recombination losses and selective electron contact. In solar cells, zinc oxide
    (ZnO) is a most favored ETL due to its visible transparency, suitable energy level,
    excellent electron mobility, and structural flexibility. Nevertheless, the current
    application of ZnO in PSCs is restricted by the undesirable reverse decomposition
    reaction at ZnO/perovskite (PVK) interface. The presence of surface hydroxyl (-OH)
    groups and interstitial zinc ions (Zn2+) speed up the decomposition process. This
    process deteriorates charge-collecting efficiency and PSC stability. By presenting
    a simple yet efficient technique for passivating the ZnO surface with chelating
    agents, glycolic acid (GlyAcid) and glycine hydrochloride (GlyHCl), we successfully
    addressed the PVK decomposition at the ZnO/PVK interface. These chelating agents
    effectively passivated the ZnO surface through the reduction of -OH groups and
    the formation of metal complex with interstitial Zn2+. It is found that, in comparison
    to GlyHCl, GlyAcid passivated the ZnO more effectively to form thermally stable
    optimum PVK on it with improved charge extraction, reduced defect density, larger
    grain size, and better energy level alignment. As a result, the ZnO/GlyAcid-based
    PSCs achieved a power conversion efficiency (PCE) of 23.09%, which is the highest
    PCE among the reported ZnO-based PSCs. Our research establishes a pathway to prevent
    PVK degradation on ZnO, allowing us to utilize its desirable ETL properties for
    PSCs.
