Predicting Organic Solar Cell Performance and Stability from Fast, Morphology-aware Current-Voltage Modeling
Yasin Ameslon, Larry Lüer, Jens Harting +2
Understanding the relationship between morphology and performance in organic solar cells is essential for developing devices that are both high performing and resilient to aging. T…
Interplay of Crystallization and Amorphous Spinodal Decomposition during Thermal Annealing of Organic Photoactive Layers
Maxime Siber, Olivier J. J. Ronsin, Gitti L. Frey +1
Tailoring the nanomorphology of organic photoactive layers through a specialized chain of processing steps is an imperative challenge on the path towards reliable and performant or…
Extending the Flory-Huggins Theory for Crystalline Multicomponent Mixtures
Maxime Siber, Olivier J. J. Ronsin, Jens Harting
The Flory-Huggins theory is a well-established lattice model that is commonly used to study the mixing of distinct chemical species. It can successfully predict phase separation ph…
Understanding the effect of drying time in process-structure-performance relationships for PM6-Y6 organic solar cells
Marc Steinberger, Maxime Siber, Hans-Joachim Egelhaaf +13
Making solution-cast organic solar cells industrially available generally comes at the cost of significant performance losses compared to device prototypes manufactured under labor…
Controlled nucleation in methylamine-treated perovskite films by artificial seeding and phase-field simulations
Emilia R. Schütz, Martin Majewski, Olivier J. J. Ronsin +2
Large perovskite crystals with reduced defect density enable superior charge transport and stability. Therefore, controlling their nucleation and growth is key to advancing high-pe…
Morphology Formation Pathways in Solution-Processed Perovskite Thin Films
M. Majewski, O. J. J. Ronsin, J. Harting
The active layer in a perovskite solar cell is usually composed of a polycrystalline thin film. Fabrication of this layer by solution processing is a promising candidate for up-sca…
