The Scanning Probe Microscopy Laboratory was founded in 2017 by Alex Redinger in a framework of an FNR consolidator grant.
The group focuses on the study of the surface of two types of thin film solar cells, namely Cu(In,Ga)Se2 (CIGSe) and hybrid organic inorganic perovskites, as well as 2D materials. We combine scanning probe microscopy techniques in ultra-high vacuum such as Scanning Tunneling Spectroscopy (STS) and Kelvin Probe Force Microscopy (KPFM) and photoluminescence imaging (PL/TRPL) to access the electrostatic and optoelectronic properties at the surface of semiconductors.
New paper in ACS Energy Letters in collaboration with the Saliba group in Stuttgart
Light makes right: laser polishing for surface modification of perovskite solar cells
We performed the PL imaging and AFM/KPFM measurements.
New paper from our group in Advanced Functional Materials:
Nanoscale Surface Analysis Reveals Origins of Enhanced Interface Passivation in RbF Post Deposition Treated CIGSe Solar Cells
Nice collaboration between UL, EMPA and LIST.
Anastasios joins the group as PhD student. Welcome!
