    摘要: Colorization of a solar cell is achieved by modifying a layer proximate an active layer of the solar cell. The color attribute may be obtained by selecting one or more narrow bands of wavelengths in the visible color spectrum to be reflected from the surface of the solar cell unit that results in a specific color or combination of colors at various angles. The spectrum of light reflected from the active solar cell area is controlled through the use of filters that reflect only limited portions of the spectrum, thereby minimizing the effect of reflected light on the overall efficiency of the solar cell.

    摘要: A photonics-based planar solar concentrator designed for collecting and guiding insolate radiation from one side to solar cells for energy conversion on another side is described. The planar solar concentrator consists of two sections. The top section is a matrix of micro-size wide angle solar concentrators. The bottom section is a planar lightwave circuit, which may be multi-layered. Planar lightwave circuits are used within a relatively thin cross-sectional thickness to guide light from micro-concentrators to output apertures on the opposite surface, such that solar cells can be located directly underneath the concentrator. The planar concentrator can deliver multiple times the normal sunlight intensity to standard silicon solar cells, thereby decreasing the number of cells required in a typical solar module. This planar solar concentrator is designed for use as the top optical layer of a standard flat panel solar module. The concentrator collects light from a relatively wide angle of incidence, and can therefore eliminate the need for active tracking.
