A new type of PV cell is comprised of a purposefully unique spatial configuration of multiple pairs of transparent thin PV films stacked top down in order of decreasing bandgaps corresponding to increasing wavelengths. Each thin-film pair is made of a material of desirable bandgap, and consecutive films separated from each other in space by a layer of air to force confinement of light waves of wavelength matching bandgap, enabling an infinite number of reflections until the wave energy corresponding to each desired wavelength is absorbed. The PV thin-films are coated to ensure that light of each wavelength is confined as intended. They are passivated to minimize surface recombination. This spatial arrangement provides multiple opportunities for photovoltaic conversion of each intended wavelength hence increasing overall conversion efficiency.

A photovoltaic module incorporates a lamination including a back-sheet, an array of solar cells supported on the back-sheet, and a transparent protective covering over the array of solar cells. The solar cells are arranged in offset or staggered patterns on the back-sheet to present a more random and less rigid industrial appearance to an observer. In some cases, cleaved solar cell segments are arranged into groups that are staggered on the back-sheet. This allows for finer control of the net voltage produced by a module. In other embodiments, full single wafer solar cells are arranged into larger groups, which themselves are staggered on the back-sheet. In either case, the result is a photovoltaic module with an appearance that is more organic and acceptable to homeowners and architects than traditional modules having cells arranged in rigid aligned rows and columns.
