Description

technical field [0001] The invention relates to a method for preparing solar photovoltaic component glass, which belongs to the field of photovoltaic device preparation. Background technique [0002] The photovoltaic industry is about receiving solar radiation and converting it into direct current output. It is a typical new energy source with the characteristics of convenient application and no pollution. At present, there are many types of photovoltaic cells, including crystalline silicon cells and thin-film solar cells (such as cadmium telluride solar cells, perovskite solar cells, and copper indium gallium selenide solar cells). For monocrystalline silicon components and polycrystalline silicon components, crystalline silicon technology is the most mature, accounting for more than 90% of the current photovoltaic power generation market. Photovoltaic power generation equipment is actually a kind of weather-resistant and durable optoelectronic device, which requires at le...
