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…

All Inkjet-printed Organic Solar Cells on 3D Objects

Marc Steinberger, Andreas Distler, Johannes Hörber +3

Drop-on-demand inkjet printing is a promising and commercially relevant technology for producing organic electronic devices of arbitrary shape on a wide variety of different substr…

On the theoretical framework for meniscus-guided manufacturing of large-area OPV modules

Fabian Gumpert, Annika Janßen, Robin Basu +4

For the manufacturing of thin films of solution-processable organic semiconductors, e.g. for organic photovoltaics (OPV), meniscus guided-coating techniques are the method of choic…

Matching the photocurrent of perovskite/organic tandem solar modules by varying the cell width

Jose Garcia Cerrillo, Andreas Distler, Fabio Matteocci +12

Photocurrent matching in conventional monolithic tandem solar cells is achieved by choosing semiconductors with complementary absorption spectra and by carefully adjusting the opti…

Cutting 'lab-to fab' short: High Throughput Optimization and Process Assessment in Roll-to-Roll Slot Die Coating of Printed Photovoltaics

Michael Wagner, Andreas Distler, Vincent M. Le Corre +8

Commercialization of printed photovoltaics requires knowledge of the optimal composition and microstructure of the single layers, and the ability to control these properties over l…

Group extensions with special properties

Andreas Distler, Bettina Eick

Given a group G and a G-module A, we show how to determine up to isomorphism the extensions E of A by G so that A embeds as smallest non-trivial term of the derived series or of th…

need not hold in finite semigroups

Andreas Distler, Victor Maltcev, Abdullahi Umar

We provide an example of minimum size of a finite semigroup with . We introduce the notion of starred stability and prove that every starr…

The semigroups of order 9 and their automorphism groups

Andreas Distler, Tom Kelsey

We report the number of semigroups with 9 elements up to isomorphism or anti-isomorphism to be 52,989,400,714,478 and up to isomorphism to be 105,978,177,936,292. We obtained these…

Coclass theory for nilpotent semigroups via their associated algebras

Andreas Distler, Bettina Eick

Coclass theory has been a highly successful approach towards the investigation and classification of finite nilpotent groups. Here we suggest a similar approach for finite nilpoten…

Finite nilpotent semigroups of small coclass

Andreas Distler

The parameter coclass has been used successfully in the study of nilpotent algebraic objects of different kinds. In this paper a definition of coclass for nilpotent semigroups is i…

The number of nilpotent semigroups of degree 3

Andreas Distler, James D. Mitchell

A semigroup is \emph{nilpotent} of degree 3 if it has a zero, every product of 3 elements equals the zero, and some product of 2 elements is non-zero. It is part of the folklore of…
