Cadmium telluride is an important material for solar cells.
(a) What is the band gap of CdTe?
(b) What wavelength of light would a photon of this energy correspond to?
(c) Draw a vertical line at this wavelength in the figure shown with Exercise 12.69, which shows the light output of the sun as a function of wavelength.
(d) With respect to silicon, does CdTe absorb a larger or smaller portion of the solar spectrum?
