摘要： A system for providing a solar harvesting building envelope is disclosed. The system includes a plurality of solar harvesting apparatus configured to be installed as or on a building envelope in manner like that of traditional shingles or siding. The apparatus includes a frame having a photovoltaic end wall, as well as reflective base and side walls. A translucent, wedge-shaped body layer is positioned on the frame. A luminescent species film is positioned at and substantially parallel to a base of the wedge-shaped body layer, such that the luminescent species film is positioned at an angle relative to the photovoltaic end wall. Light incident on the wedge-shaped body layer is concentrated towards the photovoltaic end wall, such as through absorption and re-emission along with scattering by the luminescent species film and internal reflection by the wedge-shaped body layer and the reflective base and side walls of the frame. A plurality of apparatus may be wired together to create the building envelope, which has the added advantage of substantially eliminating shading losses of traditional solar harvesting systems.

摘要： The present subject matter is an improved skylight to improved low sun-angle light collection and reduced high sun angle light and heat collection. A steeply sloping dome contains parabolic reflectors that redirect low elevation light into a light passage. The steeply sloping sides and the reflectors reflect high elevation angle rays away from a light passage.

摘要： A solar cell includes a waveguide core for receiving light, a first layer formed on the waveguide core, a second layer formed on the first layer, a third layer formed on the second layer, first metallization coupled to the first layer, and second metallization coupled to the third layer. The first layer comprises a first optical film which varies in an index of refraction in a lateral direction between a first input end where the light is received and a first output end where the light is emitted. In some embodiments, wherein one or more of the first, second, or third layers has a tapered lateral thickness. In some embodiments, the first, second, and third layers form a PIN device. In some embodiments, the waveguide core has a first index of refraction that is lower than respective indexes of refraction for the first, second, and third layers.

摘要： A method and apparatus for making reflective surfaces within optically transmissive materials. The method includes steps of providing a blade having a sharp cutting edge, penetrating an optically transmissive material with the cutting edge to a predetermined penetration depth and moving the blade relative to the transmissive material to produce a continuous slit with reflective walls. The apparatus includes a material feeding mechanism configured to feed a flexible sheet in predefined stepped increments, a slitting blade with a surface portion having a root mean square surface profile roughness parameter below 100 nanometers, and a linear drive operatively associated with the slitting blade to reciprocally move the slitting blade perpendicular to a feed direction of the flexible sheet, where a stepped feed operation of the material feeding mechanism is alternating with a reciprocal operation of the linear drive.

摘要： Embodiments described herein may relate to a system comprising a plurality of optical elements, comprising at least a first optical element and one or more secondary optical elements, a heliostat comprising the first optical element, where the heliostat is operable to move the first optical element to continuously reflect light from a non-stationary light source in a beam towards a first of the secondary optical elements, and where the secondary optical elements are arranged to re-direct the reflected beam of light towards an illumination target. The system further includes a controller configured to receive position data indicative of the position of the non-stationary light source over time, and in response to the position data, control at least the heliostat to continuously direct the beam of light towards the first of the secondary optical elements, such that the beam of light is continuously re-directed towards the illumination target.

摘要： The present invention is directed to systems, devices and methods utilizing a proxy device that indicates directional aspects of redirected light from a corresponding light redirecting element by the position of one or more redirected light beams in one or more directions or coordinates on such a proxy device. The position characteristics of light redirected from the proxy device correlate to the aim of the light redirecting element associated with the proxy. This allows the proxy information to be used to accurately determine and control the aim of the light redirecting element.
