Organize an online seminar

nanoGe is eager to promote the organization of online seminars. Do you have a topic? It's very easy to lauch a meetup! Just describe the topic, decide a few speakers, and fill the form.

Most important: We wish to encourage participation of both junior and senior researchers, please propose interesting research directions

Quantify Berlin has recently been found by a group of researchers from Helmholtz-Zentrum Berlin. We have integrated our expertise on radiative loss analysis of direct semiconductors, such as metal-halide perovskites, into an extremely compact, versatile but still easy-to-use measurement system. The setup swiftly quantifies absolute photon fluxes from electro- and photoluminescence of semiconductor layers, layer stacks or complete devices with a broad range of selectable excitation conditions. The included, user-friendly software not only records the desired luminescence spectra, but also directly calculates relevant physical parameters of the investigated sample, such as the luminescence quantum yield (EL/PLQY) or the quasi-Fermi level splitting in the absorber. A system that combines all these characterization possibilities has been lacking on the market so far.

nanoGe Online Meetup

You are invited to participate in the online meetup Advances and Challenges in Tin Halide ASnX3 Perovskites (TinPero). It will take place June 23rd at 12:00h UTC / 14:00 CEST


This e-symposium covers tin halide perovskites (ASnX3), one of the most promising new generation photovoltaic materials, as they hold excellent properties such as a close-to ideal bandgap and potential in all-perovskite tandem solar cells. Also, they show lower environmental toxicity in comparison to the predominant lead-based perovskites. Although tin halide perovskites are theoretically expected to overcome lead-based perovskites in terms of absolute power conversion efficiency, they still face many challenges involving processing conditions, the stability of Sn(II) oxidation state and suitability of contact layers.

In this online conference, we want to discuss the latest strategies used to tackle the problems affecting the efficiency and stability of tin halide ASnX3 perovskites. The conference has a particular interest in the different ways to prevent the Sn(II) oxidation, such as the use of additives (e.g. SnF2 or hypophosphorous acid) or varying the processing conditions. Similarly, the relevance of ASnX3 perovskite composition and properties of contact layers will also be emphasized.

The different topics described above will promote the discussion on unanswered aspects involving tin halide ASnX3 perovskites. While oxidation of Sn(II) is being proven by more and more research groups in the field, the working mechanisms of the additives used for this purpose are not fully understood yet. Also, what are the best strategies to obtain efficient and reproducible Sn-based perovskites? Are 2D materials the only way to achieve these goals? What implications has changing the composition in ASnX3 perovskites, and how does doping affect? Overall, this conference aims to bridge the latest advances achieved in the field with the questions so far unexplored, while keeping an eye on future challenges that tin halide perovskites will face in the near term.

Poster submissions regarding all these topics are highly welcomed. Efficiency and reproducibility of tin halide ASnX3 perovskites remain the limiting factor for the advancement of the field. Therefore, posters on this topic will be prioritized. In the same way, stability is also a crucial aspect for these materials, especially on Sn(II) oxidation, and so posters on this issue will be very appreciated. Besides, posters discussing mechanisms will make an excellent contribution towards a better understanding of the field.

Topics to be covered by the conference:
  • 1. Tin halide perovskites
  • 2. Oxidation of Sn(II)
  • 3. Ruddlesden-Popper tin halide perovskites
  • 4. Reducing additives
Meetup Presentation

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 broadcasted talks led by Invited Speakers, followed by a time for questions from the public driven by a moderator.
  • ePoster Session, where attendees and authors can share their ideas and get feedback from their colleagues worldwide through a chatroom.

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.

Present your work: ePoster Submission

All participants can present results, technical points, suggestions or doubts about methods, or formulate a question, in order to exchange information and generate scientific progress through communication. ePoster is a versatile presentation of scientific information. 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.

Oral Sessions
All Participants will receive an invitation to join the event hours before the start. The event will start at the time, but participants should join it minutes before and stay in the waiting room

The oral session will consist of presentations with slides played while the invited speaker is talking on a specific topic for about 10 min. It will be followed by questions from the audience for 10 min through the chat.

ePoster Session

Afther the Oral Sessions, there will be a 30 minutes recess before the ePoster Session. During this break, participants will receive an email with the link to the ePoster Session.

The ePoster Session will be carried through a chat platform, where participants can find a Discussion Channel for each ePoster and a General_Poster_Hall for general information.
