Improved Charge Transport and Absorption Coefficient in Indacenodithieno[3,2-b]thiophene-based Ladder-Type Polymer Leading to Highly Efficient Polymer Solar Cells

A novel ladder‐type donor (IDTT) is developed by substituting the two outward thiophenes of the IDT donor with two thieno[3,2‐b]thiophenes. The polymer derived from this donor possesses longer effective conjugation and better planarity, which improves electron delocalization along the polymer backbo...
