1. A multi band solar cell array system comprising:
a. a cross dichroic prism reflectively separating incident solar radiation into spectral components comprising a visible high band component, a visible-NIR mid band component and a NIR low band component;
b. a high band sensitive solar cell coupled to the cross dichroic prism, the high band sensitive solar cell generating electrical energy in response to the high band spectral component reflected from a first reflecting surface of the cross dichroic prism;
c. a mid band sensitive solar cell coupled to the cross dichroic prism, the mid band sensitive solar cell generating electrical energy in response to the mid band spectral component transmitted through the cross dichroic prism; and
d. a low band sensitive solar cell coupled to the cross dichroic prism, the low band sensitive solar cell generating electrical energy in response to the low band spectral component reflected from a second reflecting surface of the cross dichroic prism, wherein the second reflecting surface is different than the first reflecting surface.
