Solar Energy Without Solar Cells?

Click For Summary
SUMMARY

The discussion centers on the potential of a new solar energy technology that does not rely on traditional solar cells. Participants express optimism about its ability to significantly reduce solar power generation costs. Theoretical limits indicate that the maximum solar flux achievable is 50 million W/m², while the proposed device requires an unprecedented 100 billion W/m², raising concerns about feasibility. The community emphasizes the need for materials that can operate effectively at lower intensities to make this technology viable.

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. :-p
 
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.
