Scientists from the Karlsruhe Institute of Technology (Germany) and the University of Valencia (Spain) have developed a new method for manufacturing solar cells. This technology is expected to significantly reduce costs and accelerate the production of next-generation panels. The focus is on perovskite-silicon tandem solar cells—a modern type of panel where an additional perovskite layer is applied over standard silicon. This is reported by Ixbt.com news.
This approach allows for capturing more sunlight and increasing efficiency compared to classic silicon cells. The researchers' main breakthrough is a new vacuum-based method for applying the perovskite layer. While such processes were previously complex, slow, and unsuitable for mass production, forming the layer now takes only 10 minutes.
The technology works as follows: special organic materials are evaporated in a vacuum, particles travel a few millimeters, settle on the silicon wafer, and form a uniform working layer. This method is universal and can be applied to various types of silicon wafers without reconfiguring equipment, which is crucial for industry.
During tests, the new solar cells showed very high efficiency. At a time when standard silicon panels are approaching their theoretical efficiency limit, this result is a major step for solar energy. Another advantage of the new technology is cost-effectiveness. The method requires fewer expensive materials and allows for the reuse of some components.
