The new p-type pendant polymer for controlling bandgap and frontier orbital energy levels was synthesized by changing the carbazole motif to pyrene derivatives (P1 and P4) based on vinyl carbazole (P0). To establish the electronic properties of the pendant polymer due to molecular structural differences, the polymer was utilized as an additional hole transport layer in planar perovskite solar cells and organic solar cells. When P4 with thiophene-pyrene pendant was used as hole transport layer, device parameters were significantly improved in comparison with P0 and P1. Supramolecular assembly of P4 has proved to be more advantageous in electronic devices because P4 has more conductive thiophene units than benzene units with fewer alkyl groups. The supramolecular assembly of P4 has proved to be more advantageous in electronics because it has more conductive thiophene units than benzene units, which have fewer alkyl groups in P4.
