NEW SOLAR DEVICE COULD CREATE CHEAP AND CONTINUOUS POWER.
HOT SOLAR CELLS
nanotubes sit on top of the absorber-emitter layer, collecting energy across the solar spectrum and converting it to heat.
Black The absorber-emitter layer is situated above an optical filter and photovltaic cell, which is visible underneath.
Concentrated light from a solar simulator shines through the window of a vacuum chamber, where it reaches the solar thermophotovoltaic device and generates electricity.
