Hole transporting layers (HTL) in polymer solar cells remain a subject of importance to enable enhanced efficiency and stability compared to the benchmark PEDOT:PSS. The design of an interlayer based on the same polymer as the one used in the bulk heterojunction (BHJ) is reported here. In this HTL,...
