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.

94.82 nm

Explanation:

We have given that wavelength

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

minimum thickness is given by

here n is given n=1.45

so minimum thickness

so the minimum film thickness will be 94.82 nm

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14
