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…
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…
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…
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…
Traps and transport resistance: the next frontier for stable state-of-the-art non-fullerene acceptor solar cells
Christopher Wöpke, Clemens Göhler, Maria Saladina +17
Stability is one of the most important challenges facing organic solar cells (OSC) on their path to commercialization. In the high-performance material system PM6:Y6 studied here,…
Charge Photogeneration in Non-Fullerene Organic Solar Cells: Influence of Excess Energy and Electrostatic Interactions
Maria Saladina, Pablo Simón Marqués, Anastasia Markina +11
In organic solar cells, photogenerated singlet excitons form charge transfer (CT) complexes, which subsequently split into free charge carriers. Here, we consider the contributions…
