Journal ArticleDOI
Efficiency enhancement in low-bandgap polymer solar cells by processing with alkane dithiols
Jeff Peet,Jin Young Kim,Nelson E. Coates,Wanli Ma,Daniel Moses,Alan J. Heeger,Guillermo C. Bazan +6 more
TL;DR: By incorporating a few volume per cent of alkanedithiols in the solution used to spin-cast films comprising a low-bandgap polymer and a fullerene derivative, the power-conversion efficiency of photovoltaic cells is increased from 2.8% to 5.5% through altering the bulk heterojunction morphology.
Journal ArticleDOI
“Plastic” Solar Cells: Self-Assembly of Bulk Heterojunction Nanomaterials by Spontaneous Phase Separation
TL;DR: It is demonstrated how properly controlling the "nanomorphology", which is critically dependent on minute experimental details at every step, provides a clear path to >10% PCE BHJ cells, which can be fabricated at a fraction of the cost of conventional solar cells.
Journal ArticleDOI
Endohedral fullerenes for organic photovoltaic devices
Russel Ross,Claudia M. Cardona,Dirk M. Guldi,Shankara G. Sankaranarayanan,Matthew O. Reese,Nikos Kopidakis,Jeff Peet,Bright Walker,Guillermo C. Bazan,Edward Van Keuren,Brian C. Holloway,Martin Drees +11 more
TL;DR: This work clears a path towards higher PCEs in OPV devices by demonstrating that high-yield charge separation can occur with OPV systems that have a reduced donor/acceptor lowest unoccupied molecular orbital energy offset.
Journal ArticleDOI
Streamlined microwave-assisted preparation of narrow-bandgap conjugated polymers for high-performance bulk heterojunction solar cells
TL;DR: It is demonstrated that microwave heating in combination with the screening of comonomer reactant ratios can be used to obtain donor-acceptor copolymers with high average molecular weights and properties that make them suitable for solar cell incorporation.
Journal ArticleDOI
Improved performance of polymer bulk heterojunction solar cells through the reduction of phase separation via solvent additives.
Corey V. Hoven,Xuan-Dung Dang,Robert C. Coffin,Jeff Peet,Thuc-Quyen Nguyen,Guillermo C. Bazan +5 more
TL;DR: A high-boiling-point additive that favors both poly[(4,4-didodecyldithieno[3,2-b:2',3'-d]silole)-2,6-diyl-alt and PC₇₁BM in a bulk heterojunction solar cell is used to reduce large-scale aggregation and phase separation, which increases device performance.
