A back contact integrated photovoltaic cell includes a substrate having a dielectric surface and a patterned metal layer with parallel spaced alternately positive and negative electrode fingers forming an interdigitated two-terminal structure over the dielectric surface of the substrate. A dielectric filler may be in the interstices of separation between adjacent spaced parts of the patterned metal layer. Parallel spaced strips, alternately of p+ doped polysilicon and of n+ doped polysilicon, may top the positive and negative interdigitated electrode fingers, respectively, and form doped p-type active regions and n-type active regions of the integrated photovoltaic cell, spaced and isolated by a strip of undoped or negligibly doped polysilicon. An n− or p− doped or intrinsic semiconducting layer of at least partly crystallized silicon, forming a semiconductor region of thickness adapted to maximize absorption of photonic energy when illuminated by sunlight, may cover the interdigitated active doped regions.
