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 (Voc) and short circuit current (Isc) are nearly proportional to the evaporation height and evaporation width of the generator, respectively. Moreover, the Voc and Isc of the generator can be finely controlled by regulating the relative humidity, air flow and photo-thermal energy assistant technique.

水蒸发驱动的柔性碳化硅纳米发电机

我们已经在聚对苯二甲酸乙二醇酯(PET)基材上制备了一种灵活的自然水蒸发(NWE)驱动的碳化硅(SiC)纳米发电机。当蒸发驱动的水流经SiC材料的表面时,水与SiC之间的固液相互作用将产生连续的电能输出。本文讨论了固液相互作用的详细机理。开路电压(V oc)和短路电流(I sc)分别与发电机的蒸发高度和蒸发宽度几乎成比例。此外,V ocI sc 通过调节相对湿度,空气流量和光热能辅助技术,可以很好地控制发电机的功率。
