Thanks

Thanks. The whole of the exercise is to create a solar cell which is semi transparent.
which can be integrated into office buildings. And the way of technology provided for we're
partnering with XNX. It's a technology called morcasilicon phillisilicon alot of you are probably familiar with it.
as is used in liquid crystal displays, TV's, solar cells imaging and memory devices.
Here just shows an example one meter by one meter of morcasilicon that we've made in the
1980's. And the morcasilicon can be put down on virtually any substrate.

So this shows an example inaudible is like in a display of , like this
computer or the solar cell, and the only differ in the use of materials and configuring in a
slightly different way.

So what morcasilicon is we take a silica containing gas we break that apart into plasma and we produce
machines to produce those solar cells in central transistors.

So what they look like, something like this where since a central transistor or solar cell consists of
various layers each layer is made in the different chamber and there is a
robot in here which says to transfer the substrate from chamber A to chamber B to chamber C.


So go onto plastics we need some kind of a roll to roll process and we need to be able to make it in
a high quality way like a used in making display technology or TVs. So we
came up with an idea that's how we house a large amount of material the
plastic on a roll. And then this cassette goes into these chambers individually
to put on the different layers, so the p, the i, the n the silicon nitrite are deposited on a
piece of plastic and that makes the actual solar cell and the next one just shows a cassette. For
instance moving in one of these chambers and what is called a pulse PECDE approach to put down
a high quality solar cell.

So this shows the transmission characteristics as you make it thinner and thinner. The visible as you will
know is between 400 and 700 nanometers. As you make it thinner and thinner becomes more and more
transparent as you can see and this shows it a little bit more visually all the different colors involved.

So the next portion is to our laser scribe this in sit you as is being produced and the way it's done is shown
pictorial to here put down a transparent conducting material, laser scribe put down the next
three layers morcasilicon, laser scribe that, then put down the last layer, the ATO, and
laser scribe that to. So what happens is the top of cell touches the bottom of the next cell
and it creates Cs corrected array. Just like batteries. And that's what laser scribing, you'll
very faint lines inside the actual panel.

So. The production effectively evolves from custom tool, we can add more chambers for increased
throughput and build up the

Machines and production in step with the market.

So one megawatt plant may look something like that. We add 4 more chambers and the output starts to increase
at rapid rate.

So the bottom line is that the machines are configured. It allows for
inclusion of future technology such as nano technology, silicon technology which is what
we've been developing for the last few years. So we will be incorportating into this to make a highly efficient
pho terminal devise opique cells for real power generation.

This just shows quickly the difference between an ordinary glass wall and the fee would include the
the thin form silicon and plastic as a power glass. The differential cost between existing glasswall and the
power glass is very small. And of course is offset with power delivery from the actual solar cells.
.

So a proprietary position is actually a device configuration the production system approach as well as a lesson
as the method of semiconductors fabrication. And I think everybody is aware now the solar cells photo it takes
is groing at a rapid rate. And I dare say it, it probably has a future, so, I would like to thank you
for your attention.
