Embodiment Construction

[0084] Total internal reflection (TIR) ​​is an optical phenomenon that occurs when light rays strike a medium boundary from a higher to a lower refractive index medium at an angle greater than a specific critical angle with respect to the normal to the surface. When TIR occurs, no rays are able to cross the boundary, and all rays are reflected. The critical angle is the angle of incidence above which total internal reflection occurs. Figure 1 shows total internal reflection in a cube medium. If the refractive index n of the medium is greater than 1 / (sin45)=1.414, and the surrounding medium is air (refractive index 1), then even if the incident angle α is close to 90 degrees, the light will always is trapped inside the medium until it reaches the opposite surface.

Abstract

A transparent solar concentrator is provided for converting solar energy into electrical energy. The solar concentrator includes a first light transmissive substrate (2), a plurality of solar cells (3) for receiving solar energy and converting the solar energy into electrical energy, the plurality of solar cells positioned relative to the first substrate, and a plurality of light redirecting elements (4) arranged in the first light transmissive substrate. Each of the plurality of light redirecting elements is configured to direct light incident on a first side of the first light transmissive substrate to a respective one of the plurality of solar cells on an opposite side of the first light transmissive substrate.

Description

technical field [0001] The present invention relates to a low ratio solar concentrator device and system, and more particularly to devices and systems in which the concentration ratio varies as a function of solar declination angle. Furthermore, the invention relates to methods of design and manufacture of such devices and systems. Background technique [0002] Photovoltaic (PV) panels are becoming increasingly important as a renewable and low-carbon energy source. Combining PV panels with building structures has become a trend, the so-called Building Integrated PV (BIPV). In particular, it is desirable to incorporate PV panels in windows so that the windows can perform the function of a window and at the same time generate energy. The problem with this solution is the trade-off between requiring light to pass through the window and generating electricity at the same time. However, panels of this type already exist. Problems with such panels include that such panels gene...
