News about the group

  • 04/05/2020

Two good news this week. Firstly, we warmly welcome our new PhD student Anjala Jayaraj. She will be working on the fabrication of Sn-based perovskites and their characterizations. Secondly, we can finally go back to our labs and continue our measurements where we left them off !

Starting today and because of the COVID-19 outbreak, we will be working from home to preserve our group members' safety. We have a lot of data to analyse, papers to read and papers to write. All measurements are on hold and we hope to come back soon in our labs.

If EMRS and MRS conferences do no get canceled, Thibaut will give a talk on how stoichiometry alters the stability of MAPI at MRS. Evandro will give a turorial on Scanning Probe Microscopy, Christian will present a poster on CIGS and Alex will give a talk on KPFM of perovskite/CIGS at EMRS.
  • 01/03/2020

We welcome our new PhD student, Himanshu Phirke, who will work on the optical and electrical characterization of perovskite, CIGSe and photoferroelectric materials. This includes the development of a hyperspectral TRPL imaging setup and SPM measurements.
