HIGH THROUGHPUT MATERIAL AND PROCESSING CONCEPTS FOR PRINTED
PHOTOVOLTAICS

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.

Christoph J. Brabec is holding the chair "materials for electronics and energy
technology (i-MEET)" at the materials science of the Friedrich Alexander University
Erlangen-Nürnberg. Further, he is the scientific director of the Erlangen division of
the Bavarian research institute for renewable energy (ZAE Bayern, Erlangen), board
member of the ZAE Bavaria and board member of the Energy Campus Nurnberg.
He received his PhD (1995) in physical chemistry from Linz university, joined the
group of Prof Alan Heeger at UCSB for a sabbatical, and continued to work on all
aspects of organic semiconductor spectroscopy as assistant professor at Linz university.
He joined the
SIEMENS research labs as project leader for organic semiconductor devices in 2001,
finished his
habilitation in physical chemistry in 2003 at Linz university and joined Konarka in 2004,
where he was
holding the position of the CTO before joining Friedrich-Alexander University
Erlangen-Nürnberg
