Hi all,
Tomorrow Prof. Christoph Brabec from Friedrich-Alexander University
Erlangen-Nürnberg will talk at group meeting. See below for his title and
abstract.
All the best,

Solution processed semiconductors play an essential role in the future
renewable energy scenarios where power generation by photovoltaics will be
one of the pillars for the world´s clean energy supply. The printed organic
photovoltaics technology has evolved from the 1 % regime in the 90s to the
10 % regime nowadays. Perovskite semiconductors have lead the efficiency
pathway of printed semiconductors beyond the 20 % regime. Most
interestingly, some candidates of the most recent generation of high
performance materials show a number of unforeseen microstructure related
degradation mechanisms, which are closely related to their performance.
This presentation will outline the fundamentals of printed PV and reflect
the current state of the art, the roadmaps and the application fields of
this technology. Several concepts will be discussed in more detail, among
them the organic BHJ technology as well as the perovskite technology. A
joint roadmap towards a green, renewable & sustainable energy scenario will
be introduced, highlighting the potential of printed PV to cover mobile,
integrated as well as installed power applications.
Recent advances in material and device processing have opened a venue to
introduce high-throughput and combinatorial methods into the photovoltaics
research. First experimental investigations underpin the complexity to
introduce high throughput systematics as a concept for device engineering
as compared to material designing. The last part of the presentation will
introduce into the concept of robot based systems as a hardware platform
for high throughput device engineering.
