Faces of Chemistry: Organic solar cells (BASF) – Video 1 (11+)

Hi my name is Ingmar Bruder. I'm a
research scientist in BASF. So BASF is the largest chemical
company in the world and we're working here for instance on
plastics and dyes. So in our research labs here in BASF
we are inventing a lot of new technologies, a lot of new materials but what is equally important is to
show the people out there what we are doing here because in the end of the day they are
our customers. So in the year 2050 it is expected that about 9 billion people will live on this planet and most of them want to be mobile
and the question is how to find a way to ensure mobility in a
sustainable and cost-efficient way and one possibility could be to invent
cars which drive by electric engines.

So if you want
to develop an electric car it's much more than just replacing a
petrol or gas engine by an electric engine. Certainly you need
a good battery. But even more what you need is new
strong and lightweight materials for example fiber composites in the car
body, or wheels made out of polymers. So here in BASF we are developing organic photovoltaic, organic
solar cells, and since this is a very complex topic a
lot of different professions have to work together. Solar cells are electrical devices which convert sunlight into
electrical energy and you can find them for instance in
calculators or on rooftops.

So in these labs here, my team and myself we are developing organic
photovoltaic devices and one example that you can see here is an
organic solar cell and basically these type of devices were also used in the
rooftop of the Smart Forvision So the main advantages of organic solar
cells compared to inorganic photovoltaics is that you can produce them in
a very cheap and easy way. You can produce them basically in any
colour you want to have and they're transparent. Basically what you're seeing here is our different organic solar cells as you see they're made out of different
colours, different dyes and they are running a helicopter as a demonstrator.
But certainly this is a demonstrator and for future applications you want to
power real devices and how that might look like you can see

So basically that's a mobile phone charger powered by organic, transparent solar
cells. Basically here you see my blackberry and
I can put it here on the charger and you can see here the clock appears,
which means that my blackberry is charged at the moment. So the great thing of being a scientist
is that we have the possibility of solving the big challenges of our
generation and personally for me and my team is to
find ways of provide mankind with clean, sustainable and affordable energy..
