Solar cells are often coated with a transparent, thin film of silicon monoxide (n = 1.45) to minimize reflective losses from the surface. Suppose a silicon solar cell (n = 3.5) is coated with a thin film of silicon monoxide. Determine the minimum film thickness that produces the least reflection at a wavelength of 550 nm.

Respuesta :

Answer:

94.82 nm

Explanation:

We have given that wavelength [tex]\lambda=550\ nm[/tex]

We have to find the minimum film thickness that produces the least reflection

minimum thickness is given by [tex]t=\frac{\lambda }{4n}[/tex]

here n is given n=1.45

so minimum thickness [tex]t=\frac{550 }{4\times 1.45}=94.82\ nm[/tex]

so the minimum film thickness will be 94.82 nm
