Designing High Performance Organic Donor Molecules for Photovoltaics

Advanced Theory and Simulations, EarlyView.
Systematically tuning the fusion pattern and length of the π$\pi$‐bridge, along with adjusting the electron‐withdrawing (EW) strength of the terminal groups in small‐molecule donor A-π-Core-π$\text{A-}\pi \text{-Core-}\pi$‐A architectures, enables predictable modulation of the system's opto‐electronic properties.

Giant Small‐Molecule Donors With Controlled Backbone Planarity Afford High‐Performance and Photostable Organic Solar Cells

Advanced Science, EarlyView.
Efficient and photostable organic solar cells (OSCs) are developed using giant small‐molecule donors (GSMDs) with controlled backbone planarity. By tuning alkyl side chain orientation, anti‐configured GSMD improved crystallinity and charge transport, yielding PCE of 15.4% and superior stability (t80% > 1500 h).
