Semiconductors such as silicon are used to fabricate solar cells
— devices that generate electricity when exposed to sunlight. Solar
cells are coated with a transparent thin film, whose index of
refraction is 1.34, in order to minimize reflective losses from the
surface. A silicon solar cell (index of refraction 3.5) is coated
with a thin film for this purpose, sd in the figure.

Solar cells are given antireflection coatings to maximize their efficiency. Consider a silicon solar cell (n=3.50n=3.50) coated with a layer of silicon dioxide (n=1.45n=1.45). What is the minimum coating thickness (but not zero) that will minimize the reflection at the wavelength of 698 nm where solar cells are most efficient?

Camera lenses (n = 1.45) are often coated with a thin film of magnesium fluoride (n = 1.36). These non-reflective coatings use destructive interference to reduce unwanted reflections. Find the condition for destructive interference in this case, and calculate the minimum thickness required to give destructive interference for light in the middle of the visible spectrum (yellow-green light, λair = 555 nm).

4, Thin films. (a) A film of water (n = 1.33) in air has a thickness t = 320 nm. If it is illuminated with white light at normal incidence, what color will it appear to be in reflected light? (b) Lenses are often coated with thin films of transparent substances such as MgF2 (n - 1.38) to reduce the reflection from the glass surface. How thick t should the coating be to produce a minimum reflection at the center...

A lens made of glass (n. - 1.52) is coated with a thin film of MgF, (n = 1.38) of thickness t. Visible light is incident normally on the coated lens as in the figure below. Glass thin film Incident An illustration shows a rectangular cross- section of glass lens oriented such that a thin film of thickness tcoats its left side. A ray of light directed to the right is perpendicularly incident upon the left side of the film....
