nanoGe Online Conference

You are invited to participate in the online conference on Theory and Computation of Halide Perovskites (ComPer). It will take place on September the 8th from 08:10 UTC / 10:10h CEST and on September the 9th at 08:25 UTC / 10:25h CEST


     Bulk Hybrid Organic-Inorganic Halide Perovskites (OIHPs) with stoichiometry ABX3 (A=organic cation; B=Pb2+, Sn2+; X=halide) have revolutionized the field of low-cost photovoltaics, with power conversion efficiencies exceeding 25%. Their success is due to unique features such as high absorption coefficients, high compatibility with solution-based processing, optimal gaps for single-junction solar devices, and the very long diffusion length of the charge carriers. To date, moisture and heat-mediated degradation of OIHP-based devices still stand in the way of device mass production. However, the use of pure inorganic and 2D OIHPs, in which the short-chain, highly hydrophilic, organic A site cation is replaced by inorganic (Cs, to form both single- or double-perovskites, i.e. CsBX3 and Cs2B’B’’X6) and long-chain hydrophobic ions, respectively, has been shown to greatly reduce the degradability of the final devices.

     Theory and computation are playing a vital role in expanding our understanding of the properties behind the success of these complex and diverse materials. Advances in machine learning algorithms and computational power in the last years have opened the way towards systematically screening millions of materials for favorable optoelectronic properties. On the other hand, highly accurate methods such as Green’s function-based many-body perturbation theory are allowing to calculate the properties of quasiparticles, such as excitons and polarons, while density functional theory (DFT) and force-field based molecular dynamics are used to understand the structural stability and dynamics of halide perovskites.


     This online conference aims at bringing together experts from different fields in order to present and discuss the state-of-the-art in the theory and computation of halide perovskites.



Main topics will include (but are not restricted to):

  1. High-throughput and machine learning
  2. Material discovery
  3. Lead-free halide perovskites
  4. Quasiparticles (excitons, polarons, etc) from DFT and beyond
  5. Structural dynamics and (in)stability of halide perovskites.
  6. Defect physics
  7. Dimensionally reduced systems
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.

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.

If your Oral abstract has been accepted as Contributed Talk, you will receive an email with the abstract acceptance and the information regarding your oral slot and when it has been scheduled. Contributed talks will be broadcasted with a recorded video during the event. For this reason, we highly encourage authors to record their presentation and submit the video.

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

Videos of the conference will be available there for registered (and logged) users three months in this URL. We 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.
