TL;DR: The bulky benzene ring on the platinum(II) complex increases the steric hindrance along the polymer main chain, inhibits the polymer aggregation strength, regulates the phase separation, optimizes the morphology, and thus improves the efficiency to 16.35% is the highest efficiency for single-junction PSCs reported so far.

TL;DR: Two novel wide-bandgap copolymers, PBDT-TDZ and PBDTS- TDZ, are developed based on 1,3,4-thiadiazole (TDZ) and benzo[1,2-b:4,5-b']dithiophene (BDT) building blocks, which exhibit the stronger optical absorption, lower-lying HOMO level, and higher crystallinity.

TL;DR: It is shown that low-cost noncovalently fused-ring electron acceptors are promising to achieve high-efficiency organic solar cells and solar cells based on these acceptors demonstrate very low non-radiative energy losses.

TL;DR: PBDB-T:IDT-OB-based devices exhibit high and balanced hole and electron mobility and give a high power conversion efficiency (PCE) of 10.12% and are not very sensitive to the film thickness.

TL;DR: In this work, highly efficient ternary-blend organic solar cells (TB-OSCs) are reported based on a low-bandgap copolymer of PTB7-Th, a medium-band gap copolymers of PBDB-T, and a wide- bandgap small molecule of SFBRCN, which exhibit a broad composition tolerance with a high PCE over 10% throughout the whole blend ratios.
