Solved Solar cells -devices that generate electricity when
Solar cells -devices that generate electricity when exposed to sunlight- are often coaled with a transparent, thin film of silicon monoxide (SiO, n1 =1.45), to minimize reflective losses from the surface. Suppose that a silicon solar cell (Si, n2 = 3.5) is coated with a thin film of silicon monoxide for this purpose (Fig. 1).
