  • Keep updated to the latest version.
  • Do not share user or conference ID or passwords.
  • Do not share the url (web address) that reaches you to access.
  • Do not download Zoom from unofficial websites
  • .Verify that the emails you receive to access our conferences are from, or
nanoGe Online Meetup Conference

You are invited to participate in the online Meetup Methods to analyze stability of perovskite-type absorbers and solar cells. It will take place on Tuesday 2nd and Wednesday 3rd June at 13:00h UTC (15:00h CEST).


Perovskite solar cells demonstrated impressive power conversion efficiencies exceeding 25%, while their practical application is still significantly impeded by poor operation stability. This online conference is aimed to promote discussion and exchange of knowledge on the methods and techniques used to analyze and characterize different types of degradation effects in perovskite films and solar cells.

During the first day, we plan to focus on advanced approaches for designing absorber materials with improved stability and methodology to study their aging under the action of elevated temperatures, light and/or electric field. In addition, environmental degradation such as oxidation, hydrolysis and other atmosphere-dependent effects will be considered. In a broader context, we will discuss interface degradation effects occurring at grain boundaries and between the device functional layers (HTL, ETL, absorber, contacts) induced by certain stress factors or their combinations. Special attention will be paid to the advanced strategies of material design and characterization for reaching improved operational stability of perovskite solar cells. Is the interface passivation the key component to enable commercially interesting perovskite PV lifetimes?

During the second day of the conference, we will discuss the studies of operational stability of perovskite solar cells. We will mostly focus on the experimental procedures that can account for properties specific to perovskite solar cells (such as ion redistribution under electric fields, bias-dependent degradation, reversible character of degradation, challenges of device encapsulation, etc) and to distinguish ambient-induced degradation from other stress factors. Unlike efficiency measurements, stability experiments might take very diverse forms and have a broad range of parameters to take care of. This makes it difficult to reproduce and compare the results between different groups. Unified procedures for stability studies and consistency in data reporting could lead to the creation of a large machine-readable database on perovskite photovoltaic stability. One the lectures will be specifically devoted to machine learning (ML) methods that could potentially identify patterns in the degradation experimental data, detect statistically significant stress factors, correlate repeated phenomena in different studies to detect universal degradation mechanisms and stabilizing approaches, and predict lifetimes and failure modes.

We welcome poster submissions to all these topics, and more broadly about how to detect defect states in halide perovskites and how to avoid them, different types of defects, and fundamentals of recombination via these defects.

Meetup Presentation

 Methods to analyze stability of perovskite-type absorbers and solar cells is an online seminar that aims to promote exchange and discussion around

This online seminar brings the scientific conference gathering to the desktops or smartphones of scientists worldwide. Researchers can present their work and keep up with cutting-edge research in the field while reducing their carbon footprint, improve the work-life balance and keep the sense of community.

It will consist of two parts, in which interaction will be the main force:

  • The Oral Session will consist on a few short talks led by Invited Speakers, followed by a Discussion Pannel in which they will answer the questions from participants.
  • ePoster Session, where attendees and authors can share their ideas and get feedback from their colleagues worldwide through a chatroom and Flash Talks in Zoom.

All participants can join and present here their work. Due to the short format of the meeting (with few oral contributions), we encourage senior researchers to present ePoster, and of course we expect enthusiastic participation of junior researchers.


What do I need to join the online conference?

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 picture of your face if it is not yet in the system. You will receive the registration confirmation via e-mail.

Present your work: ePoster Submission

For fully obtaining the main goals of a scientific conference, the participation of many researchers presenting their ideas in a rich interactive context is necessary. ePoster is a versatile presentation of scientific information.

Once you are registered in the Online Meetup, you can submit your ePoster following the format explained in the information for authors. ePoster submission deadline ends on May 30th.

The ePoster will be available in the ePoster Board (you need to be registered to see this section).

Oral Sessions

Participants will receive an invitation to join the event hours before. The Zoom session will be open 15 minutes before the start of the event.

The oral session will consist of presentations with slides played while the speaker is talking on a specific topic for about 15 min. A Question and Answer chat will be available during the conference so that participants can ask questions to Speakers. They will be answered during the Discussion Pannel.

ePoster Session

The invitation to join the ePoster Chat will be sent by email before the event. You can upload and engage in ePoster discussion by accessing the chat rooms at any time (see the conference timeline). The official  ePoster Session will start after the Oral Sessions.

Join the session by using the anonymous button, and put your name so that other can recognize you. Each ePoster has its own Discussion Channel in Rocketchat. Add yourself to the channels that you consider interesting in order to to follow the progress of the discussion in the left bar. Share ideas and thoughts on the contributions presented.

Be ready to share your poster and video presentations with the broader research community in the social networks. You can follow and use the channels @nanoGe_Conf

and hashtag  #nanoGeMeetup to share your materials and see other presentations and opinions of the conference. Do not forget to reply and distribute the statements.


How to prepare and join the ePoster Session

In the ePoster you describe the contents you propose for communication and discussion. In contrast to traditional static conference posters, that present a closed scientific case, ePoster for online conference is a dynamic framework to instigate the exchange of scientific ideas and information. You can be open and imaginative, provided that the normal codes of scientific exchange are respected.

  1. Present the information so that it can be viewed quickly
  2. Make a simple design that costs you a limited amount of work

It is important that you highlight clearly the main message or information of your contribution, as is achieved in the following example.

Your ePoster will be available at the ePoster Board of the Conference. There, you have a rectangle space containing the list of authors, title, your picture and ePoster, and also (optional) a TOC, 3 min video of explanation, and a PDF file of Supporting Information (optional).

For the ePoster, use a file type that you can share easily in different media. JPG and PNG files are supported. For the video, you can attach a link to the video uploaded in Youtube.

The ePoster Session will take place in a chat platform where you will find:

  • A Directory with a channel for each of the ePosters. ePosters will be identified with the code assigned and the surname of the author.
  • A General_Poster_Hall with some basic information about all the eposters, provided by the authors and a direct URL to join their channel.

Discussions on each poster should be carried in the assigned room. Interact with participants about the topics of your interest and visit as many ePoster discussion rooms as you are interested in through the Directory.

You will find more information on how to prepare your contribution and join the ePoster Session in the Instructions for authors
