Solar battery is a device that simultaneously converts and stores solar energy. In most of the cases, conversion of solar energy is achieved by means of a photoelectrode while electric energy is stored through oxidation and reduction of appropriate redox electrolytes. In the present work, a modified version of a solar battery is presented by introducing simple metal electrodes without any electrocatalysts. Thus a Zn foil plays the role of cathode during photocharging and the role of anode during battery discharging while a copper or a silver foil plays the role of cathode during discharging. The proposed design leads to the construction of a multifunctional device which provides photocharging, battery operation and a quantum-dot-sensitized solar cell functionality.

含有功能性金属电极的太阳能电池


太阳能电池是一种同时转换和储存太阳能的装置。在大多数情况下，太阳能的转换是通过光电极实现的，同时通过适当的氧化还原电解质的氧化和还原来储存电能。在目前的工作中，通过引入简单的金属电极而不使用任何电催化剂，提出了太阳能电池的改进版本。因此，锌箔在光充电期间充当阴极，在电池放电期间充当阳极，而铜箔或银箔在放电期间充当阴极。所提出的设计导致了多功能器件的构建，该器件提供光充电、电池操作和量子点敏化太阳能电池功能。
