Notwithstanding the still high quality of the photovoltaic array
in Oldenburg there have been since then major advances in
the field of photovoltaics. The PV modules available on the
market today are almost twice as efficient as the modules at
the "Energielabor".And as far as costs are concerned, there has
been even greater progress: Since the Oldenburg array went
into operation, the costs of generating electricity with photo-
voltaic technology have shrunk to a tenth of what they were
initially.And there is still plenty of room for improvement.The
intense research and development being carried out at uni-
versities, research institutes and in industry will bring further
reductions in costs and turn photovoltaics into a competitive
energy sourcewith huge potential in ten to twenty years‘ time
– even under Northern Europe‘s limited sunlight conditions.
This is the goal of the research at the University of Oldenburg.
It focuses on innovative approaches in photovoltaics that
promise to lower costs. One example is thin-film solar cells.
The application of thin-film technologies and the sparing use
of expensive semiconductor materials are expected to pro-
vide a considerable cost advantage compared to crystalline
silicon technologies. New approaches to photovoltaic cells
based on innovative organic semiconductors and semicon-
ductor nanocrystals are being combined with established
concepts, in particular solar cells made with so-called chal-
copyrite compound semiconductors. The activities of the
scientists here range from addressing purely fundamental
questions regarding materials and components to issues
relevant to the practical application of photovoltaics.
In this way the solar cell researchers, together with the other
energy researchers at Oldenburg, are forging ahead in the
field of renewable energies and helping to design the energy
supplies of the future.
