According to the American Physicists Organization Network, engineers at Oregon State University have found a method for the first time: using inkjet printing technology to successfully manufacture CIGS (copper indium gallium selenide) thin-film solar cells, the new method reduces raw material waste 90%, and through the use of some potential compounds, significantly reduced the manufacturing cost of solar cells. Relevant experts said that with the help of this technology, scientists can finally produce thin-film solar electronic devices with excellent performance, which can be manufactured quickly and at low cost.
The research was published in the professional journal "Solar Materials and Solar Cells", and scientists also applied for a patent for this technology. Although the conversion rate of the solar cell developed now is only 5%, which requires further research to improve it, scientists believe that this research will eventually lead to a new generation of solar technology.
Zhang Zhihong, a professor at the Department of Chemistry, Biology and Environmental Engineering at Oregon State University, said: "This technology has great potential and is expected to become an important new technology in the field of solar energy. So far, no one has used inkjet technology to produce energy. Working CIGS solar equipment. "
Zhang Zhihong explained that one of the advantages of the new technology is that it can significantly reduce the waste of materials. The latest technology does not use expensive vapor deposition to deposit compounds on the susceptor-this method will cause a lot of waste of raw materials; inkjet technology can not only produce accurate patterns, but also waste very little.
In addition, the latest method uses a very promising compound chalcopyrite-also known as CIGS (copper indium gallium selenide), CIGS can greatly improve the solar energy conversion efficiency. A layer of chalcopyrite is only one to two microns thick, however, the energy it captures from the photon is almost comparable to a 50-micron thick material made of silicon.
In the latest research, scientists have created an ink that uses an inkjet method to print chalcopyrite on a base with an energy conversion efficiency of about 5%. Scientists say that theoretically, they can obtain a conversion efficiency of 12%, so that they can manufacture solar cells for commercial production.
The scientists also collaborated with Greg Herman, an associate professor in the school's chemical engineering department, to study other compounds that can also be applied to inkjet technology at an even lower cost.
Many methods of manufacturing solar cells are either very time-consuming or require the use of expensive vacuum devices or toxic compounds. Scientists at Oregon State University are working to eliminate these obstacles and develop lower-cost, more environmentally friendly solar technologies. They said that the latest technology may incubate many emerging companies and provide a lot of jobs. If the manufacturing cost can continue to fall, and other obstacles are broken down one by one, one day, people can even manufacture solar cells that can be directly integrated into the roof material, so that the solar cells can truly "fly into the homes of ordinary people."
Zhang Zhihong concluded: "In summary, we have developed a simple, fast, direct, solution-based deposition process to manufacture high-quality CIGS solar cells by controlling the structure of low-cost metal salt precursor compounds at the molecular level , You can easily obtain safe, simple, and stable ink in the air.
