Embodiment Construction

[0041] figure 1 is a cross-section of a photovoltaic cell device 10 used in the device of the present invention. The section is a transverse section with photovoltaic cell device 10 extending from the paper into an extruded shape. (Actually, the material of the device could be extruded plastic.)

[0042] figure 1The device comprises a single photovoltaic cell 12 of photovoltaic material in the form of a strip 11, in this case comprising a relatively low cost monocrystalline photovoltaic material. Accordingly, the photovoltaic cell 12 is attached to and communicates with the lower surface 13 of the optical assembly 15, the optical assembly 15 comprising a solid phase transparent material 14 having a cross-sectional shape from figure 1 is clear. Thereby, oppositely shaped curved (side) surfaces 16, 17 and an upper surface 18 are provided, the curved (side) surfaces 16, 17 having a substantially parabolic or hyperbolic shape, the upper surface 18 may in some cases be flat Ye...

Abstract

The invention provides a photovoltaic apparatus comprising a photovoltaic cell comprising an optical component of transparent material of cross section having a first surface forming an entry aperture for solar radiation, a second surface forming an exit aperture for the solar radiation passing through the entry aperture, opposite surfaces which are curved in shape, photovoltaic material positioned to receive solar radiation from the exit aperture, the opposite side surfaces being shaped to provide total internal reflection of solar radiation passing from the entry to the exit apertures, a mirror surface being positioned to reflect radiation away from one of said side surfaces.

Description

Background technique [0001] In the past decade or so, optical systems for concentrating sunlight have been greatly developed in order to increase the current generated by photovoltaic cells. [0002] Examples of earlier designs include prior patent applications by the inventors of this invention: 1. Patent Application No. GB ​​0511366.7 entitled "Solar Concentrator System" filed on June 3, 2005; 2. Patent application on June 2, 2006 The patent application No. PCT / GB2006 / 002021 named "Solar Concentrator" was filed on . [0003] While such an arrangement works well, such an arrangement uses moving components, which in many cases are not desirable since an arrangement without moving components is more cost-effective due to its simplicity, maintenance Reduced and increased indirect benefits. [0004] As the sun moves across the sky, it can be difficult to provide a stationary photovoltaic cell device that can efficiently collect the sun's rays. [0005] It is desirable to reduc...
