Research group at the University of Freiburg and Fraunhofer ISE led by @pv_physicist working on optoelectronic thin film materials and novel solar cell concepts
Joined July 2022
Building on perovskite based tandems some researchers are now exploring perovskite based triple junction solar cells. Our PhD students Mina and Maryam Heydarian gathered a great team of co-authors to summarise the current state of the art. Check it out! https://t.co/jvuvixewck

We are delighted to share two recent successes: perovskite-silicon tandems with efficiencies of 30% and perovskite-perovskite-silicon triple junction solar cells with voltages over 2.8V. Both show the huge promise perovskite based multijunction solar cells hold.
Perowskit-Silicium-Tandemsolarzellen gelten als Hoffnungsträger. Ein Team vom Fraunhofer ISE konnte nun zeigen, dass auch Dreifachsolarzellen bestehend aus Perowskit-Perowskit-Silicium-Teilzellen vielversprechend sind. Neues Paper in ACS Energy Letters: https://t.co/5JPgzyp6Dq

Perovskite-Silicon tandem solar cells combine two semiconductors for high performance. Can we stack even higher? Absolutely! Check out our new paper. We stacked two different perovskites on top of silicon to achieve a remarkably high voltage of over 2.8V!

We are delighted to be part of this key project to upscale #perovskite-silicon #tandem solar cells! Many thanks to @BMWK for the support! Together with a great interdisciplinary team from all across @FraunhoferISE we will take on this important challenge. #solarenergy
We are building an independent technology platform for #perovskite-silicon tandem #solar cells. Its task: to investigate promising routes for the scalable and economical production of these tandem solar cells. More information here: https://t.co/XHFQt5jXIK

In his brand new study, Ph.D. student Oussama Er-raji monitored perovskite films with X-rays, as the films form, to understand more about the crystallisation and tune it for more efficient solar cells. Check out the colour maps and efficiency improvements! https://t.co/G3Y2hKNY74

They wore the lab coats well! What a deligth to welcome a group of very keen girls to the lab today. They did an expert job doing optical and electron microscopy. We chatted about solar cells and life as a scientist. They had such great questions for us! #girlsday2023
We are very excited to welcome the scientists of the future to our lab next week! Experiments are prepped, and extra small lab coats are ready to go! #girlsday2023 #WomeninSTEM
