Solvent Additives: Key Morphology‐Directing Agents for Solution‐Processed Organic Solar Cells
TL;DR: Despite concerns over their environmental toxicity and role in device instability, solvent additives remain relevant morphological directing agents as research interests evolve toward nonfullerene acceptors, ternary blends, and environmentally sustainable solvents.
Journal ArticleDOI
Design of Nonfullerene Acceptors with Near‐Infrared Light Absorption Capabilities
Jaewon Lee,Seo-Jin Ko,Martin Seifrid,Hansol Lee,Caitlin McDowell,Benjamin R. Luginbuhl,Akchheta Karki,Kilwon Cho,Thuc-Quyen Nguyen,Guillermo C. Bazan +9 more
Journal ArticleDOI
Organic solar cells processed from green solvents
TL;DR: In this paper, solution-processed organic solar cells illustrate challenges inherent in processing π-conjugated semiconductors from sustainable polar solvents, and the choice of processing conditions strongly influences the self-assembly of the complex multi-component morphology required for effective charge generation and extraction.
Journal ArticleDOI
Synergistic Impact of Solvent and Polymer Additives on the Film Formation of Small Molecule Blend Films for Bulk Heterojunction Solar Cells
Caitlin McDowell,Maged Abdelsamie,Kui Zhao,Detlef-M. Smilgies,Guillermo C. Bazan,Aram Amassian +5 more
TL;DR: In this article, the power conversion efficiencies of a solution-deposited bulk heterojunction (BHJ) molecular blend film used in solar cell fabrication were investigated via in situ monitoring of absorbance, thickness, and crystallinity.
Journal ArticleDOI
Toward Additive‐Free Small‐Molecule Organic Solar Cells: Roles of the Donor Crystallization Pathway and Dynamics
Maged Abdelsamie,Neil D. Treat,Kui Zhao,Caitlin McDowell,Mark A. Burgers,Ruipeng Li,Detlef-M. Smilgies,Natalie Stingelin,Guillermo C. Bazan,Aram Amassian +9 more
TL;DR: The ease with which small-molecule donors crystallize during solution processing is directly linked to the need for solvent additives, and a donor material that crystallizes directly from solution yields additive-free solar cells with an efficiency of 7.6%.
