A hypothetical PV solar cell in space can utilize solar radiation between 0.8 and 1.1 μm in wavelength. Estimate the maximum theoretical efficiency for this solar cell facing the sun using the ideal blackbody curve of the sun as the source. Supposing that all the radiation outside the spectral range utilized by the solar cell for generating electricity is dissipated into heat, estimate the rate at which a module of solar cells of 1.0 m² area would have to be cooled to maintain the temperature of the module below 90°F.
