Sneak peek of the first plenary session: "Devices in Evolution: Pushing the Efficiency Limits and Broadening the Technology Portfolio"
The Monday morning scientific opening sessions at the
EU PVSEC always aim to excite and inspire the
conference participants for the week to come.
This year’s opening will take you on a mini tour
along the frontiers of photovoltaic technology: how we
can bring silicon technology even closer to perfection
and which new approaches may build on, or complement
silicon PV in global markets in the foreseeable
Dr. Mathieu Boccard of EPFL in Switzerland will share
with you how the total losses in already very advanced
silicon heterojunction solar cells can be reduced even
further, by finetuning contact designs to reach an
optimum combination of optical and electrical
parameters. It is an important example of the efforts
to bring silicon PV ever closer to perfection.
Approaches with similar features have been applied
successfully during the evolution of high-efficiency
silicon homojunction cells. Prof. Robby Peibst
of ISFH in Germany will take us beyond these important
developments aimed at narrowing the gap between actual
cell performance and efficiency limits of
single-junction solar cells. He will show us how the
limits of current commercial silicon and thin-film PV
technologies, which are almost exclusively
single-junction, can be exceeded. Among the different
options offered by science and technology, tandem
devices, in which two cells of materials with
different opto-electronic properties are stacked, have
progressed most on their way to large-scale
manufacturing and flat-plate (i.e. non-concentrator)
application. The appearance of perovskites in the
global PV arena has greatly accelerated tandem
developments. This offers an excellent bridge to the
presentation of Dr. Stephan DeLuca of EMC, who will
discuss perovskite research in the USA as well as the
path to commercialization, including the ambitions for
large scale manufacturing and use of this new PV
technology. Perovskites do not only offer a concrete
route to very high efficiencies in tandems, but also a
novel approach to PV module and foil manufacturing and
a range of new applications. This makes them an
exciting and highly relevant subject, well suited for
this Opening Session.
The global PV community and its stakeholders
are in the great position to already have
technologies available to take us into the
terawatt regime soon, and still to have much
more to come. These new options will make the
global PV development even more robust, offer
higher performance and open up new application
fields. You are invited to join this session!
