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: In this paper, low bandgap small molecules, BDTTNTTR and BDTSTNTTR, with benzo[1,2-b:4,5-b′]dithiophene (BDT) as the central donor unit and naphtho[1.2-c:5,6-c′]bis[ 1,2,5]thiadiazole (NT), which were also π-bridged with terthiophenes on both sides, and end-capped with 3-ethylrhodanine

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.

TL;DR: A wide bandgap small molecular acceptor, SFBRCN, containing a 3D spirobifluorene core flaked with a 2,1,3-benzothiadiazole (BT) and end-capped with highly electron-deficient RCN units, has been successfully synthesized as a small molecularacceptor (SMA) for nonfullerene polymer solar cells (PSCs).

TL;DR: The study provides an efficient nonfullerene acceptor for matching P3 HT donors but also develops a promising processing technology to realize high-performance P3HT-based polymer solar cells with an efficiency over 8%.
