| Summary: | 9,10-Phenanthrenequinone (PQ)-based molecules exhibit excellent electrical and chemical properties, making them promising building blocks for electronic and energy-related applications. In the present study, we investigated PQ-based interlayers in perovskite solar cells (PSCs) to enhance the performance of these devices. A series of diaryl-substituted PQ derivatives was synthesized and incorporated, as an interlayer, between the perovskite absorber and Spiro-OMeTAD hole transport layer in a n-i-p device architecture. Most derivatives improved the fill factor, while that with thiophene also increased the open-circuit voltage. Optoelectronic and structural analysis suggests that the introduction of a suitable PQ-based interlayer, influenced by aryl group modifications, enhances hole transport and reduces recombination losses. These findings highlight this approach as a promising strategy for optimizing PSC efficiency. |
