Claim:
1. A flexible, CPV array having an incident light conversion efficiency ranging from 12% to 23% or larger, the CPV array comprising: a substantially flat reflective surface; a plurality of photovoltaic single-junction or multi-junction cells, each of the plurality of cells having a substantial semispherical shape, and configured to collect radiation from substantially all directions and from the reflective surface; a concentrating lens having a semispherical shape, the lens configurable to concentrate incident light onto the reflective surface and directly onto the plurality of photovoltaic cells; a conductor configured to conduct electricity and heat from the plurality of photovoltaic cells; and a tubular optic sleeve configured coaxially around the CPV array, the tubular optic sleeve being fabricated from at least one light-transmitting material chosen from the list consisting of PMMA and silicone, wherein the CPV array is exposed to incident solar radiation to generate electricity without an incident solar tracking mechanism.
