A combined diffusion/rate equation model to describe charge generation in phase-separated donor-acceptor blends
Phillip Teschner, Atul Shukla, Dieter Neher
The power conversion efficiency (PCE) of organic solar cells (OSCs) has been largely improved by the introduction of novel non-fullerene acceptors (NFAs). Further improvements in P…

On the critical competition between singlet exciton decay and free charge generation in non-fullerene-based organic solar cells with low energetic offsets
M. Pranav, A. Shukla, D. Moser +16
In this era of non-fullerene acceptor (NFA) based organic solar cells, reducing voltage losses while maintaining high photocurrents is the holy grail of current research. Recent fo…

Anticorrelated Photoluminescence and Free Charge Generation Proves Field-Assisted Exciton Dissociation in Low-Offset PM6:Y5 Organic Solar Cells
Manasi Pranav, Thomas Hultzsch, Artem Musiienko +5
Understanding the origin of inefficient photocurrent generation in organic solar cells with low energy offset remains key to realizing high performance donor-acceptor systems. Here…
