    Abstract: Sunlight is localized at a solar cell by means of a lens in conjunction with a solar energy trap with very low losses. The lens is a standard magnifying lens which concentrates the sunlight to a spot which is a small percentage of the total area of the lens. The lens is fixed at a tilt angle which is in accordance with the latitude of the site of the solar collection. The daily arc of the sun across the face of the lens produces a smooth arc path of the spot in three dimensional spaces. At or near the smooth arc in space, a guide which may be a secondary mirror surface or an opening guides the light into a solar trap. The solar trap is a fully mirrored enclosed space which permits light to enter but not leave the trap. The light in the trap is guided to a solar cell within the trap with reflected and scattered light being absorbed by the solar cell.
