The thickness is only 50 microns! China's high-end manufacturing is once again leading the world!
Recently, we've heard some more good news about high-end manufacturing. Recently, Jiangsu Institute of Technology, LONGi Green Energy Technology and Curtin University in Australia have jointly developed a 50 m thick crystalline silicon thin-film solar cell.
This is the world's first crystalline silicon heterojunction solar cell with high flexibility and high power density, which is another milestone in China's high-quality processing and will continue to guide the development trend of photovoltaic technology in the world.
Nowadays, solar cells can be divided into two types, one is crystalline silicon and the other is thin film.
Silicon-based silicon cells using silicon as the main raw material are the most mature and widely used solar cells. And in terms of thin-film batteries, there are many kinds of materials, such as copper indium gallium selenide, cadmium telluride, perovskite, gallium arsenide, etc.
Although thin-film batteries have abundant raw material options, they are still dominated by silicon crystalline cells due to their low energy conversion efficiency and short lifespan, which cannot achieve large-scale, industrialized and commercialized products.
Through the unremitting research of Chinese enterprises, breakthroughs have been made in many fields such as flexibility and power density, not only to achieve ultra-thin silicon wafers below 50 m, but also to make great innovations in the fields of surface passivation and doped contact growth.
Finally, a breakthrough in this technology will increase its conversion efficiency between 57-125 m to 2606%-26.81% of new records.
The reason why such a high conversion efficiency can be achieved is entirely because of the breakthrough in this technology, which allows the thickness of crystalline silicon cells to reach a sheet of A4 paper, and it can even be folded.
Since it can be bent, and it is thinner and more efficient than thin-film batteries, its photoelectric conversion efficiency will be greatly improved, which will greatly expand our domestic battery market.
At present, the crystalline silicon solar cell has entered the mass production stage, and the R&D personnel will continue to explore softer and more efficient crystalline silicon solar cells, hoping to make the silicon crystal thin film into a thin film in the future, so that the thin film can be made into a thin film.
There is no doubt that this is a revolutionary technological advance, and Chinese researchers have made significant progress in continuous research and research.
This important breakthrough not only shows China's scientific and technological strength in cutting-edge manufacturing, but also brings new vitality to the world's photovoltaic industry.
China is currently the world's largest photovoltaic power generation country, and the world's photovoltaic industry is also experiencing a "Chinese storm".
According to foreign reports, China's photovoltaic module production capacity currently accounts for 80% of the world's total, including 88% of the world's polysilicon and 92% of silicon wafers, and Chinese companies occupy an absolute advantage in the global photovoltaic market.
According to customs statistics, the total export value of China's main raw materials for optoelectronics (silicon wafers, cells and modules) is 4906.6 billion US dollars, with a cumulative export of 18.18 million tons, an increase of 25 over the same period last year6%, indicating the rapid development of China's solar industry.
However, there has been a huge increase in China's exports of solar products, and there are three important factors for this.
First of all, China has made great strides in the process of developing and manufacturing solar cells, and at the same time improving the quality of their products.
China's photovoltaic power generation enterprises will continue to carry out scientific and technological innovation to continuously improve their performance and quality. China is also working hard to increase production capacity to meet the needs of the increasing world market, so that China occupies a more important position in the world photovoltaic industry.
Secondly, countries around the world have higher and higher requirements for new energy, and clean new energy with solar energy as the main representative is favored around the world.
With the increasing demand for new energy around the world, many countries in the world are increasing their investment in new energy sources such as solar energy. China is also conforming to the world's new environmental protection trend, constantly promoting the development of the photovoltaic industry, and helping enterprises to explore overseas markets through policy support and market stimulation.
In addition, China's photovoltaic power generation equipment has a strong cost performance due to its strong manufacturing capacity and high cost performance.
China's PV companies are vigorously exploring overseas markets, especially in emerging and developing countries, strengthening cooperation with other countries, promoting more PV products, and promoting the transformation of the world's energy landscape.
With the increasing pressure of international and domestic environmental protection, China's photovoltaic industry will pay more and more attention to sustainable development, enhance environmental awareness, and promote the construction of green manufacturing and green chain, so as to provide new momentum for the sustainable development of the photovoltaic industry.
The gratifying achievements of China's PV industry in 2022 are not only an affirmation of past achievements, but also a strong testimony to the continued leadership of China's PV industry.
Under the continuous demand for clean energy from all over the world, China's photovoltaic power generation industry will continue to develop rapidly, making positive contributions to the world's new round of energy transition and environmental protection.
