Thats pretty interesting. Hopefully they find a way to do this with a lower intensity.
If its true, I think it has tremendous potential.
Sure. Looks like it could greatly reduce the cost of generate solar power. We'll have to wait and see though. :tongue2:
Can it be made work at lower intensities? The maximum possible concentration ratio for sunlight is < 50 000 times (for a cell immersed in a medium of refractive index = 1). For a direct normal irradiance of 1000 W/m^2, this gives a maximum solar flux on the cell of 50 million W/m^2. According to the article such a device would require 10 million W/cm^2 = 100 billion W/m^2. This is 2000 times higher than the theoretical limit, so I hope they can find some materials requiring a lower intensity.
