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:

Another topic: We are looking for a postdoctoral candidate to study and understand non-geminate recombination in OPV on the basis of a newly developed 5 level model. A strong background in device physics is highly appreciated. If interested, contact me directly via neher@uni-potsdam.de

a non-scientific comment: what happened yesterday in the German parlament, that the Christian Demographic Party (CDU) enforce a decision on significantly tighter migration rules with the planned help of the right-winged AFD is an is an unbelievable scandal. German scientists can't stay silent now

Asymmetric side-chains work - Nature Materials A new series of non-fullerene acceptors with asymmetric branched alkyl chains are developed to achieve more than 20% efficiency organic solar cells.

a News and Views has been published in Nature Materials which discusses a recent record-breaking OPV work published in the same issue: doi.org/10.1038/s415...

Mitigating triplet loss in 2D WSe2/non-fullerene heterostructures using halogenated acceptors Two-dimensional transition metal dichalcogenides (2D TMDCs) can be combined with organic semiconductors to form hybrid van der Waals heterostructures. Specially, non-fullerene acceptors (NFAs) stand o...

We got another nice paper published where we use transient absorption to investigate the charge transfer between a 2D WS2 monolayer and different NFAs. Please have a look at pubs.rsc.org/en/content/a...

Here we would like to share exciting news from our group, such as new publications, open positions, new members etc. Feel free to follow us, but also to share your work.

Best wishes

Dear all,
this is the new bluesky account of the Neher-Labs, the Soft Matter Physics and Optoelectronics group at Potsdam University We have deactivated our account on X in view of its transformation into a portal for misinformation and right-wing populism.
