Journal ArticleDOI
Single-Junction Polymer Solar Cells with 16.35% Efficiency Enabled by a Platinum(II) Complexation Strategy
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.
Journal ArticleDOI
Realizing Over 13% Efficiency in Green-Solvent-Processed Nonfullerene Organic Solar Cells Enabled by 1,3,4-Thiadiazole-Based Wide-Bandgap Copolymers
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.
Journal ArticleDOI
Realizing 19.05% Efficiency Polymer Solar Cells by Progressively Improving Charge Extraction and Suppressing Charge Recombination
TL;DR: In this paper , the authors improved the charge extraction and suppressed charge recombination of polymer solar cells through the combination of side-chain engineering of new nonfullerene acceptors (NFAs), adopting ternary blends, and introducing volatilizable solid additives.
Journal ArticleDOI
Development of large band-gap conjugated copolymers for efficient regular single and tandem organic solar cells.
TL;DR: The synthesis and characterization of two conjugated copolymers, PBD TFBZO and PBDTFBZS, consisting of dialkylthiol substituted benzo[1,2-b:4,5-b']dithiophene donor and monofluorinated benzotriazole acceptor blocks are demonstrated, indicating that they are promising polymer donor materials for future application of large-area polymer solar cells.
Journal ArticleDOI
Highly efficient halogen-free solvent processed small-molecule organic solar cells enabled by material design and device engineering
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
