Online Conference

You are invited to participate in the International Conference on Impedance Spectroscopy and Related Techniques in Metal Halide Perovskites (PERIMPED). It took place from  6th to 7th October 2020, at 08:00 UTC (10:00 CEST-Berlin-Paris).

The advances of perovskite solar cell require the understanding of materials and devices by characterization techniques. In this online conference we analyze properties of perovskite solar cells and optoelectronic devices using time and frequency domain methods. The most widely used technique and the focus of the conference is on the method of Impedance Spectroscopy, that opens a set of problems of method and interpretation. Some of these problems are:

  • Basic interpretation of equivalent circuit models applied to perovskitte sola cells.
  • Physical factors influencing the response such as ionic motion and recombination.
  • Low frequency capacitance.
  • Interpretation of negative capacitance.
  • Low frequency noise, stability and reproducibility of response.
  • Measurement of defect and doping levels.

The physical characterization of perovskite materials and devices also uses related techniques that will be of interest in this conference, insofar as they have a relation with Impedance Spectroscopy, such as the Intensity Modulated Photocurrent Spectroscopy (IMPS) and time transient methods as TAS and photovoltage decays. We will discuss problems of measurements, mechanistic behaviors, and models used to describe the physical responses.


  • Impedance Spectroscopy Fundamental Aspects and applications
  • Interpretation of metal halide perovskites by frequency domain techniques
  • Ionic effects
  • Defect physics
  • Time transient methods 
What do I need to join?


In order to register to the conference, you need to sign up at nanoGe and buy your ticket.

Submit your contribution

Once you are registered you will be able to submit your contribution in the ‘Abstract Submission’ tab. You can submit:

  • Contributed Talk
  • ePoster

After the program is published, the oral abstracts not accepted as Contributed Talk can be presented as an ePoster. Please read the ‘Instructions for Authors’ tab.

Please check the submissions’ deadlines.
