Welcome to Fabio Le Piane, new Postdoc in our POPULAR research unit on printed organic solar cells! :) Fabio will work on Machine Learning, jointly with Rod MacKenzie @oghmanano.bsky.social

We are offering a postdoc position on simulations/machine learning for printed organic solar cells (+optionally experiments) @deibellab @TUCphys in coop with Rod MacKenzie @oghmanano.bsky.social – Duration about 2 years. Details: mytuc.org/knsv

Jan Anton Koster visited our group in Chemnitz @tucphys.bsky.social, and gave an excellent physics colloquium talk on „Charge transport phenomena in doped organic semiconductors: towards efficient thermoelectrics“. Was great to catch up with you, Jan Anton, and think of nice research ideas with you!

Are you interested in pursuing postdoctoral research on solution-processed semiconductors/optoelectronics via the Marie Skłodowska-Curie or Humboldt Research Fellowship frameworks?

Our Optics and Photonics of Condensed Matter group (@deibellab.bsky.social) led by @deibel.bsky.social has recently advanced the understanding of the working mechanisms of organic solar cells by shedding some light on the transport resistance. More info: www.tu-chemnitz.de/tu/presseste...

A recent perspective taking a closer look at the transport resistance in OPV and strategies to minimize these charge collection losses in future solar cells has just appeared online:

Our institute was very happy to support a lecture hall full of school students participating in the Saxonian Physics Olympiad (www.lzphysik-chemnitz.de). The festive lecture was delivered by Thomas Seyller, ...

Project meeting of our DFG Research Unit POPULAR in Dresden. Thanks to Yana et al for hosting us at IFW! We are a very good team:) popular-printed-photovoltaics.de @tucphys.bsky.social

Maria's recent GEMS talk on "Decoding the JV curve: insights into the physics of organic solar cells" is now on YouTube, youtube.com/watch?v=ongu... @gem-series.bsky.social

Congrats to Chen's & Maria's 1st "first and last author paper", a perspective on transport resistance in organic solar cells: advanced.onlinelibrary.wiley.com/doi/full/10.... – really enjoyed writing in close collab w. our splendid coauthors Dieter Neher, Thomas Kirchartz, Uli Würfel, Rod MacKenzie

This week for the #PhDPostdocSeries we welcome Maria from @deibellab.bsky.social.

She will teach us how to decode losses in #OPV!

Maria's paper "Transport resistance strikes back" is now published: https://doi.org/n687 – very nice, and a professional experience @ioppublishing.bsky.social! To celebrate, I wrote a short blog post on transport resistance, which limits the fill factor in organic solar cells https://wp.me/pbZgX-d0

Beautiful double rainbow from the Institute of Physics in Chemnitz @tucphys.bsky.social #cometoChemnitz

No colloquium this Thursday, but a great event instead.
If you want to know what coold topics and techniques are used in which of our working group - drop by and chat with our professors and staff along some with some drinks and snacks. This is a great opportunity to identify thesis topics ;)

Congratulations to Maria, who defended her PhD thesis on Fill Factor Losses in Organic Solar Cells today: very well done! Thanks to the committee Martin Breugst @breugstlab.bsky.social, OlavHellwig and Rod MacKenzie! @tucphys.bsky.social

New spectrometer as late Xmas present! Looking forward to use it in our close cooperation with @kretschmerlab.bsky.social and with @skahmn.bsky.social @tucphys.bsky.social !

As Christmas is drawing closer, the physics department held one of its all-time favorite public events: the Christmas Lecture! 🎄

To the cheers of an exhilarated audience, Prof Schwarz and Dr Schletter pulled out all the stops and showed some of the best experiments in the collection - CU next year!

Two preprints on transport resistance in organic solar cells: joint review with Dieter Neher, Thomas Kirchartz, Uli Würfel & Rod Mackenzie, lead by Maria and Chen. Discussing & writing, really enjoyable! arxiv.org/abs/2412.13694 – And research by Maria, arxiv.org/abs/2404.06190

Season's Greetings from Chemnitz!

Our DFG research unit P☀PULAR also celebrates Xmas → Thanks to Jacob Müller for designing the logo, and Martin Dehnert for 3d-printing it! popular-printed-photovoltaics.de @tucphys.bsky.social

Xmas time… preparing for presents;-)

Our „social lab“ (the room with the coffee machine;-) is nicefied – we are getting ready for Xmas time… @tucphys.bsky.social

Hiring: open PhD position DC2 in Chemnitz researching efficient organic solar cells within www.eiffelproject.eu. If you like experimental device characterisation & modelling, consider joining us at Institute of Physics in Chemnitz. Start 02/25, Deadline 9th Dec. www.tu-chemnitz.de/verwaltung/p...

Blog post on pitfalls when measuring recombination lifetimes in organic solar cells – this is on the capacitive lifetimes due to (dis)charging carrier concentration across the device capacitance: blog.disorderedmatter.eu/2024/08/22/p... – please have a look if you care:)
