That is talking about heat and power cogeneration, not solar power if that's what you're thinking. The paper they site [0] says the density can 300-400kW/m^2 and so at 300kW, 50% efficiency and a small C5 envelope you're looking at over 5kW.

- usrusr 7y agoSolid-state cogen that is simple to include in heating furnaces would be very interesting for old stock high density residential in cold regions. Mire modern heating options than gas furnaces (various variations of heat pumps, usually coupled with solar) don't scale down to individual flats and anything more central (ideally district heating) is effectively impossible to retrofit in a free market economy. But the very high efficiency electricity conversion component of cogen is just too good to skip, so a smallest-scale cogen option would be a welcome addition to the energy mix.

The key idea is that the amount of light would be the equivalent of 280 suns so you don't need a large panel.
