June 28, Oregon State University engineers have found a way first: the successful use of inkjet printing technology to produce a CIGS (copper indium gallium selenide) thin-film solar batteries, a new method to reduce raw material waste by 90% and through the use of the rich potential of compounds, significantly reduces the manufacturing costs of solar batteries. Experts said that with the technology, scientists can ultimately produce excellent performance, can be rapid manufacturing, low cost thin-film solar electronics.
The study published in the professional journal “Solar Energy Materials and Solar Cells”, the scientists have also applied for a patent for this technology. Although developed the solar battery conversion rate of 5%, of taking a step forward needs to be improved, but scientists believe the research will eventually lead to a new generation of solar technology.
The latest study, scientists create an ink jet method to use, can chalcopyrite printed on the base, about 5% energy conversion efficiency. Scientists say that in theory, they can get 12% conversion efficiency, so you can create a commercial production of solar cells.
Scientists also and Greg Herman, associate professor of Chemical Engineering school to study other inkjet technology can be applied to the compounds, the cost even lower.
Many ways to make solar cells are either very time-consuming or require expensive vacuum equipment or toxic compounds. Oregon State University scientists are working to eliminate these obstacles and developed a cheaper, more environmentally friendly solar technology. They said that the latest technology may be hatching a lot of new businesses, providing a large number of jobs. If you can continue to lower manufacturing costs, other barriers were 11 break, one day, it can even be directly integrated into the manufacturing of roofing materials in solar cells, solar cells so that the real “flying into the homes of ordinary people.”
Zhang Zhihong, concluded: “Overall, we have developed a simple, quick, direct, solution-based deposition process to manufacture high-quality CIGS solar cell approach, by controlling the low-cost metal salt precursor compound at the molecular level structure , can easily access to safe, simple, stable ink in the air.
