Photovoltaic Blend Microstructure for High Efficiency Post-Fullerene Solar Cells. To Tilt or Not To Tilt?

August 5, 2019
Author(s)
Subhrangsu Mukherjee, Dean M. DeLongchamp, Gang Wang, Steven M. Swick, Micaela Matta, Joseph Strzalka, Thomas Aldrich, Ferdinand Melkonyan, Antonio Facchetti, Tobin Marks, Jenna L. Logsdon, Simone Fabiano, Wei Huang, Tony Yang, Amod Timalsina, Natalia Powers-Riggs, Joaquin Alzola, Ryan M. Young, Michael R. Wasielewski, George C. Schatz
Achieving efficient polymer solar cells (PSCs) requires a structurally optimal donor–acceptor heterojunction morphology. Here we report the combined experimental and theoretical characterization of a benzodithiophene–benzothiadiazole donor polymer series

Stable Postfullerene Solar Cells via Direct C-H Arylation Polymerization. Morphology-Performance Relationships

May 16, 2019
Author(s)
Subhrangsu Mukherjee, Thomas Aldrich, Weigang Zhu, Lee J. Richter, Eliot Gann, Dean DeLongchamp, Antonio Facchetti, Ferdinand Melkonyan, Tobin Marks
The scope of the environmentally benign direct C-H arylation polymerization (DARP) process is validated and significantly extended in the synthesis of a high-performance benzodithiophene- based copolymer series, PBDT(Ar)-FTTE, with previously untested and

Morphological characterization of fullerene and fullerene-free organic photovoltaics by combined real and reciprocal space techniques

May 26, 2017

Donglin Zhao, Qinghe Wu, Luping Yu, Harald Ade, Dean DeLongchamp, Lee J. Richter, Subhrangsu Mukherjee, Andrew Herzing
Morphology can play a critical role in determining function in organic photovoltaic (OPV) systems. Recently molecular acceptors have showed promise to replace¬ fullerene derivatives as acceptor materials in bulk heterojunction solar cells and have achieved
