TL;DR: Chlorination demonstrates effective ability in enhancing the device performance and facile synthesis route, which both deserve further exploitation in the modification of photovoltaic materials.

TL;DR: A new benzodithiophene unit is developed and subtle side-chain modulation of the ester greatly influences the aggregation effects and molecular packing of polymer PDTB-EF-T, demonstrating the great potential of the DTBDT-EF unit for future organic photovoltaic applications.

TL;DR: The strong push-pull effect decreases the vibrational relaxation, which makes IT-4F more promising than IT-M in reducing the energetic loss of organic solar cells and a power conversion efficiency of 13.7% is recorded in PBDB-TF:IT- 4F-based devices.

TL;DR: This work offers a simple and viable option of HTL modification to realize highly efficient OSCs by mixing WOx nanoparticles with a poly(3,4-ethylenedioxythiophene):polystyrene sulfonate emulsion, the surface free energy of the HTL is improved and the morphology of the active layer is optimized.

TL;DR: Fullerene-free organic solar cells show over 11% power conversion efficiency, processed by low toxic solvents, and the applied donor and acceptor in the bulk heterojunction exhibit almost the same highest occupied molecular orbital level, yet exhibit very efficient charge creation.
