Embodiment Construction

[0050] In the following description, whenever a specific aspect or feature of an embodiment of the present invention is said to comprise or consist of at least one element from a group or a combination thereof, it is intended to It is understood that the aspect or feature may comprise or consist of any element of the group alone or in combination with any other element of the group.

[0051] As used herein, the word "optical axis" when used in the context of discussing a reflective light collector means the axis of symmetry of the reflective light collector.

[0052] As used herein, the word "decenter" when used in the context of discussing a reflective light collector refers to the fact that the mechanical center of the decentered reflective member is not on the optical axis of the reflective light collector. Similarly, the word "concentric" as used herein when used in the context of discussing a reflective light collector refers to the fact that the mechanical center of each...

Abstract

The present invention provides a reflective light concentrator. A system for generating electricity is disclosed. The system for generating electricity includes a reflector component including two decentered reflective members disposed in a symmetric relationship relative to an optical axis, wherein each of the two decentered reflective members is a segment of a cylinder, and a photovoltaic cell disposed coincident with the optical axis. A system including a plurality of electricity generating systems is also disclosed.

Description

technical field [0001] Generally, the present invention relates to the field of light energy harvesting systems. More specifically, the present invention relates to systems for harvesting light energy from a source that may be in motion, such as the sun, and concentrating such light energy via techniques including reflection. Background technique [0002] Photovoltaics is the field of technology and research directed at the development of devices called photovoltaic cells, which include one or more "photoactive" surfaces and have the ability to convert light energy incident on these photosensitive surfaces into electrical energy. For example, the light energy may be solar light energy. Environmental considerations are the main motivating factor driving the development of photovoltaic cells. A portion of current power generation technologies, such as employing coal-fired, etc., have large carbon and / or sulfur emissions or "footprints." Carbon and / or sulfur released into th...
