Online Conference

You are invited to participate in the International Conference on Impedance Spectroscopy and Related Techniques in Metal Halide Perovskites (PERIMPED). It will take place from  6th to 7th October, 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:

- the basic interpretation of equivalent circuit models applied to perovskite solar cells;

- the physical factors influencing the response such as ionic motion and recombination;

- the low frequency capacitance;

- the interpretation of negative capacitance;

- the low frequency noise and the stability and reproducibility of response;

- the measurement of defect levels;

- the measurement of 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.



Topics to be covered by the conference:

  • Impedance Spectroscopy Fundamental Aspects and applications
  • Interpretation of metal halide perovskites by frequency domain techniques
  • Ionic effects
  • Defect physics
  • Time transient methods
Submit your contribution

There will be three types of contributions:

  •  Invited speakers. Oral contribution by invitation of the organizing committee
  • Contributed talks by oral abstract submission
  • ePoster

In order to present an oral contribution you need to submit an abstract and select your preference for oral contribution. Contributed talks will be selected by the organizing committee. Oral abstracts not selected for oral will have the chance to be presented as an ePoster. For presenting an ePoster contribution it is necessary to present an ePoster before the deadline for ePoster submission.

Invited Speakers will receive an invitation via e-mail. They have to register and submit an abstract of their contribution before the deadline for oral abstract submission.

What do I need to join?


In order to register to the conference, you need to log in nanoGe (or create an account if you are not registered yet) and buy a ticket as usually. Upload a profile picture if it is not yet in the system. You will receive the registration confirmation via e-mail.

Submit your contribution

Participants can be part of the program presenting their work to the audience through a Contributed Talk or an ePoster. Once you are registered in the conference, you will be able to submit your contribution in the Abstract Submission tab.

Join the live conference

Two hours before the start of the Oral Session, the Live Conference tab will be available at the conference website. Participants should log in and enter the tab, where they will have access to the streaming video for the Oral Session and a direct buttom to the ePoster Session platform.

Join the ePoster Session

The ePoster Session chat platform will be available during the conference through the Live Conference tab. There, a “Go to conference” buttom will be available for participants to join the chat platform at any moment. The ePoster Session starts officially after the Oral Sessions. The instructions on how the chat platform works are available in the Instructions for participants and will be explained at the end of the Oral Sessions.

Conference on demand

Registered participants will have access to the videos of the Oral Sessions on demand. Videos will be available there for registered (and logged) users for three months. It will allow them to rewatch the best moments in case they have missed any session. nanoGe will upload the videos after the sessions and make them available in a private tab for conference members.  

For non-registered users, the conference will be available on-demand after the conference. Once you buy the ticket for an on-demand conference, you will have access to the videos for three months.
