Problems solved by technology

[0002] While sunlight, a source of energy for solar power, is seemingly plentiful and fuel-free, these benefits of sunlight are offset by the relatively expensive nature of photovoltaic (PV) cells for solar power
Also, due to the relatively low efficiency of these PV cells, the PV cells need to occupy a relatively large area in order to generate a sufficient amount of electricity

Embodiment Construction

[0015] In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the inventive subject matter. It will be apparent, however, to one skilled in the art that the inventive subject matter may be practiced without these specific details. Additionally, methods, apparatuses or systems that would be known by those skilled in the art will not be described in detail so as not to obscure the claimed subject matter.

[0016] Throughout this specification, "an embodiment" may refer to a particular feature, structure, or characteristic described with respect to a particular embodiment, which may be included in at least one embodiment of the present invention. Thus, appearances of "in one embodiment" in various places in the specification are not necessarily intended to refer to the same embodiment or to any one particular embodiment described. Furthermore, it is to be understood that particular features, structures or ch...

Abstract

An optical system for light energy concentration may comprise a light concentrator to convert incident light to converging light, a light collimating element to receive the converging light and to reduce an angle of convergence of the converging light, and a light directing element to direct the reduced-angle converging light to a light guide to transmit the directed light.

Description

【Technical field】 [0001] The invention disclosed herein relates to an optical system, and more particularly to a concentrated photovoltaic system for concentrating light energy. 【Background technique】 [0002] While sunlight, an energy source for solar power generation, appears to be plentiful and fuel-free, these benefits of sunlight are offset by the relatively expensive nature of solar power photovoltaic (PV) cells. Also, due to the relatively low efficiency of these PV cells, the PV cells need to occupy a relatively large area in order to generate a sufficient amount of electricity. Therefore, improving the efficiency of PV cells will reduce the cost of solar power generation and / or increase the installed capacity of solar power generation. [0003] Concentrated Photovoltaic (CPV) systems use optical elements to concentrate sunlight onto relatively small solar cells, reducing the use of expensive solar cell materials. CPV technology is a very important method of conver...
