” ….The secret sauce – Morgan’s concentrated solar module

Morgan Solar is developing a concentrated solar photovoltaic module that should be ready for market by the summer of 2014. Instead of a solid panel of silicon like a typical solar module, concentrated solar uses a device to focus the light onto a tiny, ultra-efficient photovoltaic cell.

There are other concentrated solar PV companies and products out there, but the secret sauce for Morgan is in their optics. To gather and focus the light they use a lens made of cheap, everyday plastic called poly methyl methacrylate or PMMA.

“It’s used to make automotive headlamps, it’s used to make paints and it’s extremely cheap. So we’re replacing expensive semiconductor materials with really inexpensive polymer materials and that’s kind of key to reducing the cost of the raw materials that go into the solar panel,” says John Paul Morgan.

The solar cell that the light is focused on is the same stuff that’s shot into space and used to power satellites.

“One wafer would cost 400 times, 500 times more than a silicone solar cell, but it’s much, much, more efficient. And when you dice that up and when you use a tiny sliver in the middle of a concentrator, you can get superior economics,” says John Paul Morgan.

Morgan is an engineer, a physicist and is an expert in fibre optics. It’s this experience that inspired him to make a lens that redirects the incoming light 90 degrees sideways to the middle of the lens where the tiny solar cell is waiting. This means the lens used to focus the light is cheap and much thinner than its competitors….”
