Morphological Features

Ideal morphological features are of particular importance to produce high performance all-polymer solar cells (all-PSCs), in which active blends generally involve unfavorable phase separation due to complicated intermixing.

Side Chains

High-performance all-polymer solar cells were developed by employing an asymmetric benzo[1,2-b:4,5-b′]dithiophene unit with one thiophene and one 4-methoxythiophene conjugated side chain in the donor polymer, which enabled fine-tuning of energy levels and phase separation.
