Abstract

A planar solid-state photocapacitor with two electrodes has been prepared for the first time using a passivated film of ZnS with AgS quantum dots deposited on ZnO nanorods, which were electrochemically grown on ZnO seed layers, as the photoanode. The supercapacitor part is composed of a electrodeposited poly(3,4-ethylene-dioxythiophene) PEDOT film as the counter-electrode and an ionic liquid-based electrolyte between them deposited by the dip coating method. The different nanostructures and electrodes were morphologically and structurally characterized, and the device was electrochemically characterized and could reach a potential of 0.33 V during photocharge and a storage efficiency of 6.83%.

摘要

首次制备了一种具有两个电极的平面固态光电电容器，其光阳极采用沉积在ZnO纳米棒上的带有AgS量子点的ZnS钝化膜，这些ZnO纳米棒是在ZnO种子层上通过电化学方法生长的。超级电容器部分由电沉积的聚（3,4-乙烯二氧噻吩）PEDOT膜作为对电极，以及通过浸涂法沉积在它们之间的离子液体基电解质组成。对不同的纳米结构和电极进行了形态和结构表征，并对该器件进行了电化学表征，在光充电过程中可达到0.33 V的电位，存储效率为6.83%。
