Transmission of power into solar cell

Application: Transmission of power into solar cells. Consider the question of generating electricity with silicon solar cells. The relative permittivity of silicon at optical wavelengths is 1.75 and it may be considered to be lossless. Assume uniform plane waves, perpendicular incidence, and internal conversion efficiency of the cells is 25%. The Sun power density at the location of the cells is 1400 Wlm2 •

(c)     Calculate the power per unit area of the cell it can generate and its overall efficiency.

(d)     Suppose a new type of material is designed which has properties identical to those

of silicon except that its permittivity equals that of free space. How much larger is the power that solar cells made of this material can generate and its efficiency?
