Abstract: A manufacturing process of silicone glass concentrator lens, wherein, a mold is provided with a material inlet hole and an air outlet hole that are respectively used for pouring in liquid silicone and exiting air respectively. Wherein, firstly, the mold is connected to a glass carrier plate in a vertical arrangement, then pouring the liquid silicone into the mold through the material inlet hole, thus exiting the excessive air through the air outlet hole of the mold automatically. Through the application of this manufacturing process, a bubble-free silicone glass concentrator lens can be made in a fast manner without the occurrences of liquid silicone overflow, hereby reducing the production cost.

Abstract: A concentration photovoltaic module includes a lens array and a cell array. The lens array includes lenses and alignment windows. The cell array includes solar cells and alignment points. A method is provided for aligning the lens array to the cell array. In the method, a collimation module is made with collimated light sources. The concentration photovoltaic module is located under the collimation module so that the alignment windows are located under the collimated light sources. The collimated light sources are used to turn sunlight into collimated light beams and cast the collimated light beams onto the cell array through the alignment windows. The lens array is moved relative to the cell array so that the collimated light beams are directed to the alignment points. Hence, light beams emitted from the lenses are directed to the solar cells.

Abstract: Sets of a solar cell and a lens are obtained on a surface of a solar concentrator module. The solar cell is located at a focal point of the lens. The other sets whose solar cells are replaced with lighting devices are obtained on the opposite surface of the solar concentrator module. Each later set is reversely piled up on a former set. Hence, a light shining through the later set and the former set from the lighting device is focused on the solar cell. Consequently, photoelectric characteristics of the solar concentrator module is tested with greatly reduced cost.
