Much attention to dye-sensitized solar cells (DSSCs) has recently been paid by their advantages for real-world applications such as transparency and/or multicolor options, easy integration into building architecture and short energy payback time. In this study, solid-state DSSCs with poly(3-hexylthiophene) (P3HT) as a hole transporting material (HTM) were fabricated, and their photovoltaic properties were investigated. When the P3HT was applied as HTM, a solid state DSSC showed a power conversion efficiency (PCE) of 0.77%, resulting from 1.63 mA/cm2 of the short-circuit current (Jsc), 0.682 V of the open-circuit voltage (Voc) and 69.32% of fill factor (FF). On the other hand, a device with the doped P3HT layer showed a photovoltaic performance of 6.25 mA/cm2 for the Jsc, 0.642 V for the Voc, and 62.59% for the FF, which led to a PCE of 2.51%. |
