Assuming light of arbitrary intensity is available, what is the limitation of the maximum power a solar cell can provide for a given surface area? What causes this limitation?
Assuming light of arbitrary intensity is available, what is the limitation of the maximum power a solar cell can provide for a given surface area? What causes this limitation? I’m not talking about the 1000 W/m^2 standard solar heat flux. I’ve seen fresnel lenses intensify this to nearly a point, putting a large area of solar energy into a small cell at a heat flux of hundreds of suns. What are the limits of doing this? Heat is one obvious problem, but are there others?
This has nothing to do with efficiency. Assume an arbitrary (or infinite) number of photons are cheaply available.

Peak watt (or Watt peak)

Since solar cell output power depends on multiple factors, such as the sun’s incidence angle, for comparison purposes between different cells and panels, the peak watt (Wp) is used. It is the output power under these conditions:[1]

1. solar irradiance 1000 W/m²
2. solar reference spectrum AM (airmass) 1.5
3. cell temperature 25°C
