Abstract

A new dye-sensitized solar cell driven electrochromic device has been fabricated. The device consists of an electrochromic display and a solar cell in a single nanocrystalline film. The optimization of the electrochromic and the solar cell functions was carried out. An applied potential of 1.0 V was required for coloring and the best solar energy conversion efficiency 1.1% was achieved. The efficiency may be compared to an efficiency of 4.6% obtained in a similar dye-sensitized solar cell without the display property. Coloring and bleaching times of the device were less than one second and a transmittance change from 38.7% (bleached) to 15.9% (colored) at best was achieved. The optimization of the electrochromic property of the device lead to decreasing efficiency of the solar cell and vice versa.

摘要

一种新型的染料敏化太阳能电池驱动的电致变色器件已被制备出来。该器件由一个电致变色显示器和一个太阳能电池组成，二者集成在一个单一的纳米晶体薄膜中。对电致变色和太阳能电池功能进行了优化。着色需要施加1.0 V的电势，并且实现了最佳太阳能转换效率1.1%。该效率可与在没有显示特性的类似染料敏化太阳能电池中获得的4.6%的效率相比较。该器件的着色和漂白时间小于1秒，并且最佳情况下实现了透过率从38.7%（漂白态）到15.9%（着色态）的变化。该器件电致变色性能的优化导致太阳能电池效率降低，反之亦然。
