In this work we describe a novel bifacial design concept for dye-sensitized solar cells (DSCs). Bifacial DSCs are fabricated with ruthenium complex chemisorbed double-sided TiO(2) nanotube arrays on a Ti metal substrate, in combination with two electron-collecting counter electrodes. Our investigation shows that the present bifacial DSCs have similar conversion efficiencies when illuminated from either their front or rear side, and a summated output power when illuminated on both sides. Furthermore, this type of bifacial DSC is also able to summate the output power of each side when working at an 'unsymmetrical' mode, in which much different output powers are generated by the front and rear sides. Therefore, this bifacial design concept exhibits a promising potential to reduce the cost of solar electricity when DSCs are operated at a location where a high albedo radiation is available.
在这项工作中，我们描述了一种用于染料敏化太阳能电池（DSC）的新型双面设计概念。双面 DSC 是在 Ti 金属基底上使用化学吸附的钌配合物双面 TiO2 纳米管阵列，并结合两个电子收集对电极来制备的。我们的研究表明，当前的双面 DSC 在从前侧或后侧照明时具有相似的转换效率，并且在两侧同时照明时会产生总和输出功率。此外，这种类型的双面 DSC 还能够在“不对称”模式下将每个侧面的输出功率总和起来，在前侧和后侧产生的输出功率差异很大。因此，当 DSC 在高反照率辐射可用的位置运行时，这种双面设计概念具有降低太阳能电力成本的广阔前景。
