Notch structure for concentrating module and method of manufacture using photovoltaic strips

A solar module with a light concentrator structure for photovoltaic strips, the solar module comprising:

• a front cover member including a webbing with a flat front plane, a back plane, a first thickness provided between the front plane and the back plane, a plurality of concentrating elements integrally formed in a parallel manner extending from a first edge to a second edge at the back plane, and a peripheral region free of any concentrating element, each of the plurality of concentrating elements including an aperture region, an exit region, a second thickness provided between the aperture region and the exit region, and two sides connecting the aperture region and the exit region;
• a plurality of triangular notches separating each of the plurality of concentrating elements from its neighbor one, each of the plurality of triangular notches including an apex region;
• a first radius of curvature of 0.10 mm to 0.001 mm characterizing the apex region;
• a first refractive index of about 1.45 or higher characterizing the webbing with the plurality of concentrating elements;
• an optical coupling material applied overlying all exit regions of the plurality of concentrating elements;
• a plurality of photovoltaic strips bonded to all exit regions via the optical coupling material;
• a plurality of triangular shaped regions including the corresponding plurality of triangular notches;
• a second refractive index of about 1 characterizing the plurality of triangular regions;
• and
• a back cover member including an electric circuit board and an edge wall, the edge wall being configured to clamp with the front cover member at the peripheral region, the electric circuit board including an input/output circuit block configured to couple with the plurality of photovoltaic strips;
• wherein the first thickness ranges from 5 mm to 7 mm.
