Abstract

The presence of alkali metal ions (AMIs) during the adsorption of thiolated Au nanoclusters (NCs) onto TiO₂ plays a critical role in achieving high power conversion efficiency and suppressing anomalous current−voltage hysteresis in metal nanocluster-sensitized solar cells. This hidden role of the AMIs is intimately related to the adsorption strength between the NCs and TiO₂, indicating the importance of seeking a comprehensive understanding of NC−TiO₂ interfaces and devising interfacial engineering techniques to support the next advance in light energy conversion applications of NCs.
