Photovoltaic companies are companies active in the photovoltaic solar energy production sector.
Photovoltaic companies focus on the field of photovoltaic solar power generation and realize the utilization of renewable energy by designing, manufacturing, selling and installing photovoltaic modules and solar systems. solar energy production. They are committed to developing and promoting solar energy technology, including solar panels, photovoltaic modules, inverters, rack systems and other related products, as well as providing a set of solutions such as engineering consultancy, design, construction and after-sales service. The aim of photovoltaic companies is to promote the use of clean energy, reduce dependence on traditional energy, promote sustainable development and provide thex users of reliable, efficient and environmentally friendly energy solutions.
(1) Silicon solar cells
Silicon solar cells are divided into three types: monocrystalline silicon solar cells, polycrystalline silicon thin film solar cells and polycrystalline silicon thin film solar cells. thin-film amorphous silicon solar cells.
(2) Multi-compound thin-film solar cell
The materials of multi-compound thin-film solar cells are inorganic salts, which mainly include arsenide compounds of gallium III-V, cadmium sulfide, cadmium. sulfide and copper-indium-selenium thin film batteries, etc.
(3) Polymer multilayer modified electrode solar cells
Replacing inorganic materials with organic polymers is a research direction in solar cell manufacturing that is just emerging. to start. In rayIts advantages of organic materials such as flexibility, ease of production, wide material sources and low cost, they are of great importance for the large-scale utilization of solar energy and the provision of good electricity. walk. However, research into using organic materials to prepare solar cells is only just beginning. Neither the lifespan nor the efficiency of the cells can be compared to that of inorganic materials, especially silicon cells. Whether it can become a product of practical importance remains to be studied and explored in more detail.
(4) Nanocrystalline solar cells
Nano-TiO2 crystal chemical solar cells are newly developed, and their advantages lie in low cost, simple process and stable performance. Its photoelectric efficiency is stable at more than 10% and its production cost is only 1/5 to1/10 of that of silicon solar cells. The lifespan can reach more than 20 years.
(5) Organic thin-film solar cells
Organic thin-film solar cells are solar cells whose core is composed of organic materials. It makes sense that not everyone is familiar with organic solar cells. More than 95% of mass-produced solar cells today are silicon-based, while the remaining less than 5% are also made of other inorganic materials.
(6) Dye-sensitized solar cells
Dye-sensitized solar cells attach pigment to TiO2 particles, then soak them in an electrolyte. The pigment is exposed to light and generates free electrons and holes. Free electrons are absorbed by TiO2, flow from the electrode to the external circuit, then pass through the electrical device, flow into the elementectrolyte and finally return to the pigment. The manufacturing cost of dye-sensitized solar cells is very low, making them very competitive. Its energy conversion efficiency is around 12%.
