Molecular Optimization Enables over 13% Efficiency in Organic Solar Cells
TL;DR: The PBDB-T-SF:IT-4F-based OSC device showed a record high efficiency, and an efficiency of over 12% can be obtained with a thickness of 100-200 nm, suggesting the promise of fullerene-free OSCs in practical applications.
Journal ArticleDOI
Fullerene-Free Polymer Solar Cells with over 11% Efficiency and Excellent Thermal Stability
TL;DR: A nonfullerene-based polymer solar cell (PSC) that significantly outperforms fullerene -based PSCs with respect to the power-conversion efficiency and excellent thermal stability is demonstrated for the first time.
Journal ArticleDOI
Energy-Level Modulation of Small-Molecule Electron Acceptors to Achieve over 12% Efficiency in Polymer Solar Cells
TL;DR: The two new SMAs (IT-M and IT-DM) end-capped by methyl-modified dicycanovinylindan-1-one exhibit upshifted lowest unoccupied molecular orbital (LUMO) levels, and hence higher open-circuit voltages can be observed in the corresponding devices.
Journal ArticleDOI
A Wide Band Gap Polymer with a Deep Highest Occupied Molecular Orbital Level Enables 14.2% Efficiency in Polymer Solar Cells.

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.
Journal ArticleDOI
Highly Efficient 2D-Conjugated Benzodithiophene-Based Photovoltaic Polymer with Linear Alkylthio Side Chain
TL;DR: In this paper, Chen et al. reported a photovoltaic polymer (named as PTB7-Th, see Scheme 1a) by incorporating the 2-(2ethylhexyl)-thienyl group into the benzo[1,2-b:4,5-b′]dithiophene (BDT) unit.
