Department Solution Processing of Hybrid Materials & Devices

Pillar 1: ABX3-Inspired Energy Materials

In Pillar 1, the Unger team focuses on perovskite-based and new energy materials for PV and beyond.

High-throughput compositional engineering of new materials is enabled by combinatorial Inkjet printing and slot-die coating.

Combinatorial Inkjet Printing

HySPRINT-Logo, made by combinatorial Inkjet printing

The method of combinatorial Inkjet printing of perovskite-based materials was shown in the compositional range from I-Br. [link]

Combinatorial Inkjet printing for light emitting devices

PeLED

The method was adopted in collaboration with the List-Kratochvil team in the JointLab GENFab for photodetectors  and larger area LEDs.

Combinatorial slot-die coating

combinatorial SDC

We also developed combinatorial slot-die coating, demonstrating the bandgap tuning of MAPb(BrxI1-x)3.

Currently we are working on Pb/Sn perovskites and Pb-free perovskites. Screening emerging solution-processable PV materials (e.g. Elpasolites, Rudorffites, 2D/3D perovskites)
