PROBLEM TO BE SOLVED: To provide an imaging apparatus in which a unit pixel is larger than the diameter of a microlens used in a conventional technique, and which is advantageous to layout design of pixels.SOLUTION: An imaging apparatus that has a plurality of pixels two-dimensionally arranged on a substrate and each including a photoelectric conversion unit comprises a light condensing unit that is arranged on each of the photoelectric conversion units. The light condensing unit is smaller in area than the photoelectric conversion unit.

PROBLEM TO BE SOLVED: To provide a light condensing device, such as a solar cell device, having a fresnel lens with a cover glass which is made up entirely of glass.SOLUTION: A light condensing device includes: a cover glass; a glass fresnel lens which has uneven surfaces on a first surface and a rear surface and directly contacts with one surface of the cover glass at the first surface to be integrated therewith; and a light receiving element facing the fresnel lens and disposed so as to be spaced away from the fresnel lens. The above problem is solved by including these components.
摘要:
A solar energy collection system includes a solar concentrator operative to direct a concentrated solar beam onto a solar receptor. A shutter plate is positioned between the solar concentrator and the solar receptor and is movable from an open position adjacent to the solar beam, to a closed position wherein at least a portion of the solar beam contacts a front face of the shutter plate and is blocked from contacting the receptor. A cooling circuit is operative to circulate a cooling fluid to remove heat from the shutter plate. A shutter drive is operative to move the at least one shutter plate from the open position to the closed position, and a shutter control is operative to stop movement of the shutter plate at a plurality of locations between the open position and the closed position.
