Mobility-lifetime relation links photodegradation in spin-coated and gravure-printed organic solar cells
Maria Saladina, Paul Weitz, David Holzner +24
The degradation mechanisms of organic solar cells (OSCs) have been studied primarily in spin-coated, laboratory-scale devices, whereas scalable processing modifies the device archi…
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 Çiloğlu, 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 Çiloğlu, 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…
The Physical Meaning of Time-Delayed Collection Field Transients from Disordered Devices
Markus Hußner, Carsten Deibel, Roderick Charles Ian MacKenzie
Charge carrier mobility and recombination determine the performance of many opto-electronic devices such as solar cells, sensors and light-emitting diodes. Understanding how these…
Machine learning for ultra high throughput screening of organic solar cells: Solving the needle in the hay stack problem
Markus Hußner, Pacalaj A. Richard, Olaf G. Müller-Dieckert +12
Over the last two decades the organic solar cell community has synthesised tens of thousands of novel polymers and small molecules in the search for an optimum light harvesting mat…
Comment on "Interface state recombination in organic solar cells"
C. Deibel, A. Wagenpfahl
In a recent paper, Street et al. [Phys. Rev. B 81, 205307 (2010)] propose first order recombination due to interface states to be the dominant loss mechanism in organic bulk hetero…
