Solar blackbody curve
Weba blackbody at 5250 °C, represented by the blue curve. (credit: modification of work by American Society for Testing and Materials (ASTM) Terrestrial Reference Spectra for Photovoltaic Performance Evaluation) In Figure 8.1, the solar distribution is compared to a representative distribution, called a blackbody spectrum, that corresponds to a WebWien's Displacement Law. For a blackbody radiator, the temperature can be found from the wavelength at which the radiation curve peaks. Discussion. If the temperature is = C = K, then the wavelength at which the radiation curve peaks is: λ peak = x10^ m = nm = microns. This wavelength corresponds to quantum energy. hν = x 10^ eV.
