Solar cells are devices that generate electricity when light is exposed to it. They are coated in transparent thin film, of silicon monoxide (Sio, n = 1.5), to minimize reflections.
Suppose you are designing a silicon solar cell (Si, n = 3.5), what is the minimum thickness you can apply to the surface of the cell that will produce the least amount of reflection for 552 nm of light, which is near the middle of the visible spectrum? Assume air n = 1.0.
WHY minimize the reflection from the solar cell?
Explain your answer. Thank you!
