Abstract:We have prepared a flexible natural water evaporation (NWE) driven silicon carbide (SiC) nano-generator on the polyethylene terephthalate (PET) substrate. When the water driven by evaporation flows through the surface of SiC material, the solid-liquid interaction between water and SiC will induce continuous electricity output. The detail mechanism of the solid-liquid interaction is discussed in this paper. The open circuit voltage (V-oc) and short circuit current (I-sc) are nearly proportional to the evaporation height and evaporation width of the generator, respectively. Moreover, the V-oc and I-sc of the generator can be finely controlled by regulating the relative humidity, air flow and photo-thermal energy assistant technique.
