NOVELTY - A solar cell comprises: an asymmetric compound parabolic concentrator (100) including an entrance (115) and an exit aperture (120), where the asymmetric compound parabolic concentrator includes two reflective parabolic surfaces, where each parabolic surface includes a parabolic shape distinct from the other parabolic surface; a photovoltaic cell (130) positioned near the exit aperture of the asymmetric compound parabolic concentrator such that a majority of the light incident at the asymmetric compound parabolic concentrator is directed toward the active surface of the photovoltaic cell.    USE - As solar cell (claimed) used to convert solar energy into electricity.    ADVANTAGE - The asymmetric compound parabolic concentrator (ACPC) collect light from the sun without using mechanical and/or actuating tracking devices and capture a high percentage of sun light as the sun moves through its celestial path with the sun's daily and seasonal variations. The ACPC immovably couples directly with a solar cell array without requiring the ACPC to rotate or twist to capture more sun light as the sun's path changes; delivers solar light with at least 80-95% efficiency, while maintaining a fixed position relative to any light-receiving device. The ACPC provide light at the exit aperture that is substantially perpendicular to the surface of the aperture. Light incident at the exit aperture at such a steep angle undergoes very little reflection allowing more light to exit the exit aperture.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) a preparing solar cell involving: creating a first parabolic surface; coupling a second parabolic surface with a shape distinct from the shave of the first parabolic surface; coupling the first parabolic surface with the second parabolic surface to create a concentrator with an entrance aperture and exit aperture: and coupling the concentrator with a photovoltaic cell such that the photovoltaic cell is disposed near the exit aperture of the concentrator; and    (2) a solar array comprising: a first several photovoltaic asymmetric compound parabolic concentrators, where each of the photovoltaic asymmetric compound parabolic concentrators comprise at least one photovoltaic cell and an asymmetric compound parabolic concentrator positioned to concentrate light toward the photovoltaic cell, and where each of the first photovoltaic asymmetric compound parabolic concentrators are electrically coupled in series; and a second several photovoltaic asymmetric compound parabolic concentrators, where each of the second photovoltaic asymmetric compound parabolic concentrators comprises at least one photovoltaic cell and an asymmetric compound parabolic concentrator positioned to concentrate light toward the photovoltaic cell, where each of the second photovoltaic asymmetric compound parabolic concentrators are electrically coupled in series, where the first photovoltaic asymmetric compound parabolic concentrators are electrically coupled with the second photovoltaic asymmetric compound parabolic concentrators in parallel or series, and where each of the compound parabolic concentrators include an entrance aperture, two reflective parabolic surfaces, and an exit aperture with the associated photovoltaic cell being disposed near the exit aperture of the respective concentrator where each parabolic surface includes a parabolic shape distinct from the other parabolic surface.
