Researchers use vacuum process to manufacture efficient tandem solar cells (heise.de)

• Vacuum process enables large-area perovskite deposition
• Key step for industrial production of tandem solar cells
• Combination of silicon and perovskite for higher efficiency

"Researchers have developed a vacuum process that allows large-area, uniform deposition of the perovskite layer for tandem solar cells. This is a key step toward industrial production of high-efficiency solar cells combining silicon and perovskite."
