| Abstract: | An expression has been derived for the
absorption coefficient  of an incident radiation with energy ħw by a semiconductor with band-gap  E0. For a multilayer solar cell
composed of seven layers that facilitate the solar cell to use the seven
colours of the white light for maximum efficiency, the expression for the solar
current ISC has been used
to calculate the value of the charge carrier density n in each layer. ISC
should be the same through all the layers for the layers to be connected in
optical series. For such an arrangement, the efficiency of the multilayer solar
cell turns out to be more than 42%. |
