Description

BACKGROUND OF THE PRESENT INVENTIONFIELD OF INVENTION

[0001] The present invention relates to an architectural glass made of waste solar panel and manufacturing method thereof, in particular to an architectural glass which is completely obtained from waste solar panel, cut and compounded.DESCRIPTION OF RELATED ARTS

[0002] It is noted that fossil fuels are gradually exhausted due to the continuous development of human beings, so the development of energy is extremely important, and solar power generation has become one of the development priorities of alternative energy in countries around the world. However, with the increase of the number of solar panels used, the number of waste solar panels that need to be treated by countries in the future is also increasing. The International Renewable Energy Agency (IRENA) estimates that the global solar panels will increase from 250000 tons at the end of 2016 to more than 5 million tons in 2050. The composition of the solar panel is to encapsulate the solar cells with sealing materials, such as EVA plastic, between the glass and the back plate, and then install aluminum frames around them. Ninety percent of solar cells on the market are made of silicon crystals. Therefore, the main materials of solar panels are about 75% glass, 10% aluminum, 10% ethylene vinyl acetate (EVA), and others include silicon, copper, silver, etc. Since solar panels contain recyclable and reusable materials, solar waste panels are generally recycled and reused. For example, CN 113 385 520 discloses a method for recycling solar panels. The current treatment of solar waste panels is to disassemble the aluminum frame, junction box, and cables first, then smash the waste solar panels, and then deliver the broken pieces to an incineration plant, export them overseas or reuse them, wherein after the broken glass is ground into "glass sand", it can be mixed with asphalt to pave roads or make high-pressure concrete bricks, which not only has a reflective effect at night, but also has an anti-slip function. It is an environmentally friendly building material. However, it is a pity and a great waste to break the intact glass.SUMMARY OF THE PRESENT INVENTION
