Summary: Hybridized nanogenerator composed of photovoltaic cell (PVC) and triboelectric nanogenerator (TENG) has been developed to scavenge both light and liquid-droplet energies simultaneously. The device exhibits good hybridized process and generates peak current and voltage of 16.96 mu A and 0.83 V. The maximum hybridized peak power is determined by TENG's pulselike output, while the maximum hybridized output energy is more affected by the continuous output signals of PVC.

Summary: Contact electrification and charge transfer occur at a liquid-solid interface when continuous droplets slide on the dielectric surface. We investigated the accumulation of static charges on the surface of dielectric solid materials during this process from the perspective of liquid chemistry at the atomic level. Our experiments showed that the rate of charge accumulation on the solid surface in liquid-solid systems depends on the liquid chemistry, particularly the ionic diameters of cations, concentration, and pH. This suggests that chemical factors play a significant role in charge transfer at a liquid-solid interface.
