A solar cell is designed to have a nonreflective coating of a transparent material.
(a) Will the thickness of the coating depend on the index of refraction of the underlying material in the solar cell? Discuss the possible scenarios.
(b) If n_{ {solar }}>n_{ {film }} and n_{ {film }}=1.22, what is the minimum thickness of the film for light with a wavelength of 550 {~nm} ?
a) No, the thickness depends only on the transparency of the material.
b) 226.8 nm
c) 112.4 nm
d) 45.3 nm
