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…
Towards a fully differentiable digital twin for solar cells
Marie Louise Schubert, Houssam Metni, Jan David Fischbach +18
Maximizing energy yield (EY) - the total electric energy generated by a solar cell within a year at a specific location - is crucial in photovoltaics (PV), especially for emerging…
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…
Taxonomy of amorphous ternary phase diagrams: the importance of interaction parameters
Yasin Ameslon, Hao Liu, Jens Harting +2
Understanding phase diagrams is essential for material selection and design, as they provide a comprehensive representation of the thermodynamics of mixtures. This work delivers a…
