We know that solar modules are constantly developing. In recent years, new types of solar modules have been slowly developed. So what are new types of solar modules? Let's take a look together next.
Here is the content list:
New solar modules
Thin-film solar modules
Copper Indium Selenide Solar module
At present, the average efficiency of mass-produced monocrystalline and polycrystalline silicon solar modules on the market is around 15%. Such solar modules can only convert incident sunlight energy into 15% of usable electrical energy, and the rest is converted into unusable heat energy. With the technological development of ultra-high-efficiency solar modules, in addition to the use of novel element structure design, solar modules try to break through their physical limitations but also try to introduce new materials to achieve the goal of greatly increasing the conversion efficiency. In addition, there are many subsequent solar module packaging technologies and solar module optical technologies.
In the thin-film solar module technology, it is particularly eye-catching. Thin-film solar module technology applies thin-film solar modules to building materials such as roofs, skylights, exteriors, doors and windows, and other parts of the building envelope. The advantage over non-integrated systems is that the initial investment can be offset by saving building materials and labor. It is considered to be one of the most growing technologies in the solar module industry. The advantages of thin-film solar cells are flexibility and low cost, which can be completed by deposition. The solar modules have a large area, but the conversion efficiency is not high, and there is light degradation. Amorphous silicon solar modules have a very broad spectrum absorption. It can also be made into a flexible thin-film solar module, which is of great help to green buildings and other buildings that require batteries to be attached to windows or even the surface of buildings.
Copper indium selenium thin-film solar modules have the following characteristics: copper indium selenium is a direct energy gap material, and its visible light absorption coefficient is as high as 105 cm-1, which is about 100 times more absorption than silicon-based series. It is very suitable as the absorption layer of thin-film solar modules. After the solar module technology matures, the manufacturing cost and recycling time will be much lower than that of crystalline silicon solar modules.
Solar modules have the strong anti-radiation ability. Solar modules have high photoelectric conversion efficiency. At present, the highest conversion efficiency of copper indium gallium selenide thin-film solar modules has reached 20.3%, which is the highest record among all thin-film solar modules.
The solar module has good stability, and the efficiency is stable and hardly attenuated.
Low light characteristics are good. Therefore, the copper indium selenium thin-film solar module is expected to become one of the mainstream products of the new generation of solar cells.
To better develop solar modules, the manufacturer of Anhui JF Solar Technology Co., Ltd. (JF Solar) is constantly learning and developing new types of solar modules. If you are interested in solar modules, please contact us. Our website is HTTP: //www.jf-solartech.com/.
Currently, most solar photovoltaic modules are made of crystalline silicon (c-Si) solar photovoltaic modules made of polycrystalline silicon and monocrystalline silicon. In 2013, crystalline silicon accounted for more than 90% of global photovoltaic production, while the rest of the entire market wa
