PhD-Postdoc series

Starting September 2021

The Next Generation Solar Energy (NGSE) PhD-Postdoc series aims to promote the work of Emerging Scientists (PhD students and Postdocs) in the field of solar energy. While a lot of talks in mainstream conferences are given by professors or group leaders, here only early career researchers will present in order to promote a new generation of promising scientists.
Group leaders and professors are more than welcome to attend the talks and ask questions to the speaker. In this fashion, the series will provide a platform for experienced scientists to give feedback and challenge the young generation, but also to scout for future potential collaborators and colleagues.
This series aims to facilitate discussions and to allow for deeper insights into phenomena as well as characterization techniques. As such, presentations will focus on clearly defined topics covered in-depth, rather than a list of big achievements.
The organization of the series and the selections of the future speakers is made by a committee (to be announced) also composed of early career researchers as well as past speakers.
Presentations will be given on the second and fourth Wednesday of every month at 5 PM (GMT+2) Berlin time which is 8 AM (GMT-7) Los Angeles time, 11 AM (GMT-4) Montreal, 11 PM (GMT+8) Beijing. The talks are held online (via Zoom) to ensure that researchers from around the world can present and attend. Talks will last between 20 to 30 min (max) followed by 10 min of questions.
With the speakers’ permission (embargo period possible) the talks will be recorded and uploaded to a dedicated YouTube channel. At the end of every academic year a vote (50% community vote 50% committee) will be organized to select and award the “NGSE – Best Speaker of the Year”.

Looking forward to welcome all of you to these events,

Dr. V.M. Le Corre

Next talk September 22nd at 5 PM Berlin time:

Dr. C.M. Wolff

Light management in perovskite single- and multi-junction solar cells
Abstract:
As perovskites have improved in both efficiency and stability through composition- and process-engineering, their higher efficiencies become limited by extrinsic factors such as their ability to absorb light and convert these photons into usable energy. To reduce reflection losses flat surfaces must be avoided. I will present randomly textured nanometer- and micrometer-sized structures in solution or vapor deposited lead halide perovskites and how these enable flat and almost loss-free photon-to-current spectra. The devices collect ~95% of all incoming light above bandgap. I’ll close by showing how these textures are embedded into efficient single-junctions and two-terminal tandem devices and our approaches and pitfalls when trying to upscale the processes to wafer size.
