Abstract

The 3D printing (3DP) technology offers an innovative approach to developing energy storage devices to create facile and low-cost customized electrodes for modern electronics. Generating electric potential by moving a droplet of ionic solution over 2D materials is a novel method for rain energy harvesting. This work demonstrates a liquid-solid contact electrification-based 3DP nanogenerator where raindrop passes through the positively charged ultrathin gadolinium telluride (Gd2Te3) sheets. The output efficiency of the nanogenerator is increased to ≈400% by enhancing the surface area of copious 3D-printed porous structures. The density functional theory (DFT) calculations reveal that the high electrical conductivity of (112) surface of Gd2Te3 is due to the p-type charge carriers, which help to generate electricity by interacting with the ionic solution. This work can open up a new avenue to advance scientific research on blue energy harvesting and tackle the energy crisis.
