Here, we report a novel zero-dimensional (0D) perovskite-based ionovoltaic device that efficiently harvests ambient moisture to generate electric power, which makes peorvskite be a new kinds of potential MEG. The 0D perovskite, DAP 2 PbI 6 , (where DAP is 1,3‐bis(ammonium)‐2‐hydroxypropane diiodide.) features a unique hydrogen-bonding network formed between its ammonium (–NH 3 + ) and hydroxyl (–OH) group, yielding water stability and remarkable hydrophilicity. Such robust interactions facilitate water adsorption and the subsequent release of hydrogen ions under humid conditions. These protonic species establish an ion gradient, driving a directional current via the ionovoltaic effect. We demonstrated a maximum volumetric power density of 45 mW cm -3 —substantially exceeding previously reported values for protein- or carbon-based MEG. Additionally, SEM and AFM analyses confirm the stable of DAP 2 PbI 6 upon moisture exposure, while temperature-dependent impedance spectroscopy and theoretical calculations reveal that proton diffusion is the primary mechanism for the observed moisture-driven electricity. These findings underscore the promise of hydrophilic 0D perovskite materials for high-efficiency MEG and pave the way for next-generation sustainable power applications.
