Sun catcher : The new benzo[1,2‐ b :4,5‐ b ′]dithiophene‐containing polymer PBDTTBT exhibits a power conversion efficiency of up to 5.66 %. The high open‐circuit voltage (0.92 V) originates from the low HOMO level of the polymer and the high internal and external quantum efficiencies over a wide spectral range. PBDTTBT is a promising donor material for application in polymer solar cells.
