Abstract:
1. A solar concentrator module for manufacture of solar energy conversion system, the sunlight concentrator module comprising: a webbing configured from a thickness of material and having a shape characterized by a first dimension, a second dimension, a planar region defined by the first dimension and the second dimension, the webbing having a front region, a back region, and a first thickness of at least 3.2 millimeters up to 7.2 millimeters provided between the front region and the back region; a load sustenance characteristic provided by the first thickness of the webbing, the load being at least of 2400 Pa uniformly applied on the front region for 1 hour in two cycles; a hail impact resistance characteristic of the webbing with the first thickness, the impact hail being an ice ball with at least of 25 mm diameter directed at a speed of at least 23 meter per second to at least 11 locations of the front region; a plurality of concentrator elements integrally formed with the back region excluding a peripheral region of the webbing, each of the concentrator elements being disposed one-next-to-another in parallel along the first dimension and characterized by a length, an aperture region, an exit region, a first side region provided between a first portion of the aperture region and a first portion of the exit region, a second side region provided between a second portion of the aperture region and a second portion of the exit region, and a second thickness of about 1.8 millimeters provided between the aperture region and the exit region, the length being substantially the same as the second dimension; a geometric concentration characteristic provided by a scale ratio of the aperture region to the exit region for each of the plurality of concentrator elements, the scale ratio being characterized by a range from about 1.8 to about 4.5; an optical transparency characteristic of the first thickness of the webbing combined with the second thickness of each of the plurality of concentrating elements with a transmissivity being at least of 90% and greater within a visible light range; a plurality of photo voltaic strips, each of the plurality of photo voltaic strips coupled to at least a portion of each of the exit region of the plurality of concentrator elements, each photovoltaic strip having a width substantially similar to the exit region, one or more photovoltaic strips having a cumulative length substantially similar to the length of the concentrator element, each of the photovoltaic strips comprising a silicon material; a plurality of electric conducting leads disposed along two edges of each of the plurality of photo voltaic strips, each conducting lead being conductively connected to each other and to module external electrical ports; and a rigid back cover member having substantially the same shape of the webbing and being configured to mechanically couple with the webbing; and wherein the first side region and the second side region are characterized by a root-mean-square (RMS) roughness of 30 nm and less and the first side region and the second side region expose respective portions of the thickness of material; and wherein the thickness of material comprises the first thickness and the second thickness.
