Abstract Liquid-solid contact electrification (L-S CE) has become a widely researched topic in recent years, presenting innovative approaches to enhancing traditional power supply methods. However, most research on L-S CE predominantly concentrated electrolyte solutions interacting with solid surfaces. In this study, we systematically explored, for the first time, interface formed between non-electrolytes (organic solvents) and metals. Our experiments demonstrated that simple system composed of two dissimilar metal electrodes pure ethanol can achieve maximum open-circuit voltage (VOC) 578 mV, short-circuit current (ISC) 744 nA, an output density 62.29 nW/cm². Density Functional Theory (DFT) Molecular Dynamics (MD) calculations revealed formation organic solvent induces vacuum energy level shift, facilitating spontaneous electron transfer, which underpins generation electrical signals. Furthermore, by integrating DFT experimental measurements, investigated transfer characteristics various metals solvents, measured their corresponding VOC, establishing clear relationship them. Finally, metal-organic developed study amplify signals through straightforward series parallel connections. This work establishes robust foundation further exploration non-electrolyte applications field CE.

Abstract Droplet‐based electricity generators (DEGs) harness liquid‐solid electrification to convert water droplets impacts into electrical energy. This study systematically examines how droplet height, volume, flow rate, and substrate tilt angle influence DEG performance using polytetrafluoroethylene (PTFE) as a triboelectric layer deionized water. Three electrode designs (double, top, bottom) are evaluated, revealing that the double‐electrode configuration delivers highest output. enhanced arises from synergistic motion, double‐layer formation, charge discharge, validated by an equivalent circuit model. By varying heights 1–20 cm, volumes of 7.7–50 µL, rates 50–300 drops/min, angles 0–90°, optimized setup yields −70 V 22 mA, translating power density 0.28 µW cm −2 . High‐speed imaging correlates these outputs with impact dynamics resulting transfer. Additionally, can small electronic devices, capacitors, monitor artificial acid rain in real‐time, displaying distinct signals compared typical rainwater. These findings underscore potential DEGs renewable energy harvesters smart environmental sensors, paving way for advanced on‐demand generation diverse settings.
