1. A method of manufacturing a concentrating photovoltaic cell subassembly comprising the steps of:
bonding a lead structure to a solar cell structure, the lead structure including electrical leads for the solar cell structure; and
embedding the solar cell structure and operatively connected lead structure within a transparent encapsulant by:
placing the solar cell structure into a mold filled with an encapsulant;
curing the encapsulant so as to create an encapsulated solar cell device having a first hemispheric dome portion having an index of refraction of nc2; and
separating the encapsulated solar cell device from the mold; and
placing the encapsulated solar cell device and associated lead structure into a second mold filled with lower refractive index encapsulant material to thereby perform an additional encapsulation having a second hemispheric dome portion concentric with the first hemispheric dome portion and having an index of refraction of nc1 such that nc1 is equal to a square root of nc2, and the solar cell structure is positioned at approximately 1.17*R below a top of the second hemispheric dome portion with R being a radius of the second hemispheric dome portion, and the first hemispheric dome portion has a radius of R/nc1.
