Highly uniform and transparent polyaniline (PANI) electrodes that can be used as counter electrodes in dye-sensitized solar cells (DSSCs) were prepared by a facile in situ polymerization method. They were used to fabricate a novel bifacially active transparent DSSC, which showed conversion efficiencies of 6.54 and 4.26% corresponding to front- and rear-side illumination, respectively. Meanwhile, the efficiency of the same photoanode employing a Pt counter electrode was 6.69%. Compared to conventional Pt-based DSSCs, the design of the bifacial DSSC fabricated in this work would help to bring down the cost of energy production due to the lower cost of the materials and the higher power-generating efficiency of such devices for their capabilities of utilizing the light from both sides. These promising results highlight the potential application of PANI in cost-effective, transparent DSSCs.
采用简便的原位聚合方法制备了高度均匀透明的聚苯胺（PANI）电极，可用作染料敏化太阳能电池（DSSC）中的对电极。使用它们制备了一种新型双面活性透明 DSSC，分别对应于前照光和后照光的转换效率为 6.54%和 4.26%。同时，采用 Pt 对电极的相同光电阳极的效率为 6.69%。与传统的基于 Pt 的 DSSC 相比，由于材料成本更低，并且此类设备利用两侧光线的更高发电效率，因此双面 DSSC 的设计有助于降低能源生产成本。这些有前途的结果突出了 PANI 在具有成本效益的透明 DSSC 中的应用潜力。
