Please write me a detailed answer for the following exercise.

Thank you in advance.

ro and rsc are the reflection coefficients from air to anti-reflection coating and from anti-reflection coating to semiconductor respectively, d is the thickness of the anti-reflection coating. B) Given that the refractive index of the anti-reflection coating material, nar = 1.9 for all wavelengths, calculate the thickness of the anti-reflection layer in nanometers that Jane needs to deposit to obtain a perfect quarter wave coating at A = 500 nm, such that R = 0. Give the answer in [nm]. Hint- For destructive interference use d=lambda/(4*refractive index) C) With the thickness for the anti-reflection coating found in question B), Jane measures the reflectance of the wafer again. Calculate the reflection R that Jane can expect from the coated wafer at a wavelength of A = 1100 nm, given that at this wavelength nsc = 3.5. Give your answer in two decimals.

The reflection coefficient for a crystalline silicon solar cell for light incident from air, neglecting absorption, is given by: (п — 1)2 R = (n + 1)2 Jane has measured the reflection of a bare crystalline silicon wafer at a wavelength of 500 nm using the reflectance setup. She obtained a value of R = 0.39. A) Considering the interface from air to silicon, determine the refractive index of silicon at a wavelength of 500 nm. 4.32 4.32 Jane now deposits a single-layer anti-reflection coating on top of the crystalline silicon wafer. The reflection coefficient now becomes more complex: + ršc + 2ror sc cos 2,3 R = 1+ r% + 2rorsc cos 23 with Пar — По nsc - nar ro rsc ;and B = Nar d. nar + no nsc + nar
