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...

Transport Resistance Dominates the Fill Factor Losses in Record Organic Solar Cells Organic photovoltaics are a promising solar cell technology, but even the record devices with 20% efficiency have significant fill factor losses due to low active layer conductivities. In this Perspe...

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:

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

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
