The Silver price is at a 10-year high, >$1500/Kg, after more than doubling in the last two years. And copper inks prices are declining.

“This breakthrough opens up a significant opportunity for silver-free HJT solar cell production without additional investments in production equipment and more complex manufacturing processes. It also offers excellent potential for application in future high-efficiency perovskite/silicon tandem solar cells.” Yu Wu, Principal Investigator at TNO’s Solar Energy Group
