Abstract
The interfaces between different materials in the heterojunction colloidal quantum dot (QD) solar cell play an important role for charge carrier separation, recombination and collection. Here, an organic-inorganic hybrid p-i-n architecture for the heterojunction PbS QD solid solar cell is constructed to increase the charge extraction and reduce charge recombination. Heavily doped poly(3-hexylthiophene-2,5-diyl) (P3HT) is applied as hole transport interlayer between the QD film and metal contact electrode. The results show that the P3HT interlayer diminishes the charge carrier recombination at the QD film/metal contact electrode interface leading to increased open-circuit voltage and increased electron life time. Furthermore, after incorporation of P3HT interlayer an additional p-i heterojunction might form at P3HT/QD film interface resulting in increased depletion region, which promotes charge carrier extraction under working conditions. Two other organic p-type interlayers are also investigated, however, the results indicate that a barrier for charge extraction is formed for these devices, which is explained by the difference in energy levels. The solar cell with the P3HT interlayer exhibits a power conversion efficiency of 5.1% at 1 sun of illumination and ambient atmosphere, which is similar to 20% higher compared to the solar cell without any hole transport interlayer.
