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…
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…
A Framework to Pinpoint Bottlenecks in Emerging Solar Cells and Disordered Devices via Differential Machine Learning
Cai Williams, Chen Wang, Alexander Ehm +4
A key challenge in the development of materials for the next generation of solar cells, sensors and transistors is linking macroscopic device performance to underlying microscopic…
Transport resistance dominates the fill factor losses in record organic solar cells
Chen Wang, Roderick C. I. MacKenzie, Uli Würfel +4
Organic photovoltaics are a promising solar cell technology well-suited to mass production using roll-to-roll processes. The efficiency of lab-scale solar cells has exceeded 20% an…
