We are now at the organic electronics or
plastic electronics laboratory where
we are developing all sorts of different
devices like light emitting diodes
solar cells, and transistors for electronics
When we started our activity at the
Technion some 15 years ago we focused
our attention on organic light-emitting
diodes Most people nowadays know organic
light emitting diodes as the OLED
screens that Samsung and LG are
developing and selling largely in
smartphones but already in TVs
As you can see nowadays we are actually
embedding them in 3D objects but this is
really more of the past in terms of our
research and what we are focusing today
more is on solar cells and one of the
advantages of plastic solar cells is
that you can really mount them on
plastics
so this is really a plastic foil and all
of it is covered by conducting
plastics and with that we can really
build solar cells on plastic foils and
since these are really lightweight and
sometimes are colorful you can really
mount them everywhere on buildings
windows on your backpack and we can
really have a lot of power everywhere
But unfortunately always with simplicity come
some problems and the efficiency of these cells and their ability to deliver power
is limited so what we actually did in
this research that we have been
progressing on solar cells is develop a 
new device architectures as a device
engineers we realize that we can build a
structure that will contain a higher
built-in potential
So while we lose some of it on the way
we can still have enough power to
deliver and we can really use these
cells and solar cells for applying the
power to different appliances and we
believe that this now will make them
really commercially viable throughout
the world and of course the cities
