Dependence of charge separation efficiency on the exciton-charge transfer offset and Gaussian disorder in organic solar cells
Maik Schwuchow, Carsten Deibel, Angela Thränhardt
State-of-the-art organic solar cells increasingly rely on low-offset semiconductor blends, challenging the traditional requirement of a large energetic driving force for efficient…
Rethinking Charge Transport and Recombination in Donor-diluted Organic Solar Cells
Chen Wang, Christopher Wöpke, Toni Seiler +12
We systematically investigate PM6:Y12 bulk-heterojunction solar cells with donor fractions ranging from 1% to 45%, linking morphology, charge transport, and recombination to device…
Bridging the lab-to-fab gap in non-fullerene organic solar cells via gravure printing
Svitlana Taranenko, Chen Wang, David Holzner +10
Organic solar cells have reached record efficiencies with non-fullerene acceptors, yet their translation to industrial printing remains a critical bottleneck. Here we report the hi…
Modeling and Simulation of Device Performance in Organic Photovoltaics
Pelin ÃiloÄlu, Carmen Tretmans, Carsten Deibel +4
We present a pipeline to study the device performance of organic solar cells in silico. We introduce a mathematical model that includes the dynamics of excitons as well as their di…
The contribution of electron and hole conductivity to the transport loss in organic solar cells
Chen Wang, Toni Seiler, Doyoung Sun +3
The effective conductivity determines the reciprocal of the transport resistance, the dominant loss of fill factor in organic solar cells. We experimentally determine the dependenc…
Visualizing the Link Between Nanomorphology and Energetic Disorder in 3D Organic Solar Cells
Pelin ÃiloÄlu, Carmen Tretmans, Carsten Deibel +3
The performance of organic bulk heterojunction (BHJ) solar cells is highly sensitive to both nanomorphology and energetic disorder arising from microscopic molecular packing and st…
