# Question

A solar cell is designed to have a nonreflective film of a transparent material for a wavelength of 550 nm.

(a) Will the thickness of the film depend on the index of refraction of the underlying material in the solar cell? Discuss the possible scenarios.

(b) If nsolar > nfilm and nfilm – 1.22, what is the minimum thickness of the film?

(c) Repeat the calculation in (b) if nsolar < nfilm and nfilm = 1.40.
