Identifying structure-absorption relationships and predicting absorption strength of non-fullerene acceptors for organic photovoltaics
Jun Yan, Xabier Rodriguez-Martinez, Drew Pearce +15
Non-fullerene acceptors (NFAs) are excellent light harvesters, yet the origin of such high optical extinction is not well understood. In this work, we investigate the absorption st…
The dynamics of internal electric field screening in hybrid perovskite solar cells probed using electroabsorption
Davide Moia, Ilario Gelmetti, Philip Calado +7
Electric fields arising from the distribution of charge in metal halide perovskite solar cells are critical for understanding the many weird and wonderful optoelectronic properties…
Driftfusion: An open source code for simulating ordered semiconductor devices with mixed ionic-electronic conducting materials in one-dimension
Philip Calado, Ilario Gelmetti, Benjamin Hilton +3
The recent emergence of lead-halide perovskites as active layer materials for thin film semiconductor devices including solar cells, light emitting diodes, and memristors has motiv…
Design and evaluation of conjugated polymers with polar side chains as electrode materials for electrochemical energy storage in aqueous electrolytes
Davide Moia, Alexander Giovannitti, Anna A. Szumska +7
We report the development of redox-active conjugated polymers with potential application to electrochemical energy storage. Side chain engineering enables processing of the polymer…
Influence of the Hole Transporting Layer on the Thermal Stability of Inverted Organic Photovoltaics Using Accelerated Heat Lifetime Protocols
Felix Hermerschmidt, Achilleas Savva, Efthymios Georgiou +7
High power conversion efficiency (PCE) inverted organic photovoltaics (OPVs) usually use thermally evaporated MoO3 as a hole transporting layer (HTL). Despite the high PCE values r…
