Effects of controlled slot-die-printing on halide perovskite films — •Meike Kuhn, Christopher Greve, and Eva M. Herzig — Dynamik und Strukturbildung - Herzig Group, Universität Bayreuth, Universitätsstr. 30, 95447 Bayreuth, Germany

Perovskite solar cells gained a lot of interest because of their steeply increasing efficiency in the last years. But Perovskite materials in general are of strong interest due to their transport properties which are strongly linked to their nanostructure. There are different ways to deposit perovskite films, but for fabrication of large-area films methods like spin coating are hard to realize. So it is important to improve the fabrication of films by printing. By using a slot-die-printing system, we test different environmental control parameters and solvents to get a homogeneous perovskite layer. These parameters determine the structure of the perovskite layer [1] and thus the transport performance.
