摘要： A solar radiation collector is provided. The collector is configured to receive solar radiation from a range of angles including a first range constituting an acceptance angle, and a second range constituting angles outside said first range. It further comprises a photovoltaic cell and a regulator, which is configured to regulate the appearance of the collector to an observer within the second range, constituting a source of visible radiation which is visible to an observer within the second range.

摘要： A solar radiation collector comprising a concentrator and a photovoltaic cell, the concentrator comprising at least a prismatic primary portion, the primary portion comprising primary entrance aperture having a perimeter, an outer surface adapted for receiving radiation, and a inner surface; a primary receiver plane; sidewalls, meeting the primary entrance aperture along at least a portion of the perimeter; and a reflective bottom surface. The primary portion is adapted to utilize total internal reflection at least from the inner surface of the primary entrance aperture to concentrate radiation entering through the primary entrance aperture toward the primary receiver plane. The primary entrance aperture comprises a reference area defined as the area thereof between two lines, each of the lines being the intersection between the primary entrance aperture and an imaginary plane which is perpendicular to both the primary entrance aperture and an extreme end of the primary receiver plane; the total area of the primary entrance aperture substantially exceeding that of the reference area.
