This didn't appear to capture the full article. I can only see two sentences of reporting. This is the second sentence: The new technology comes from an Israeli startup that promises to simplify one of the most cumbersome steps in solar manufacturing and cut costs by reducing the amount of silver needed to capture sunlight on the panels. Based on another blogger's report it appears that the solar manufacturer is Hanwha Qcells, a Korean solar manufacturer with some manufacturing in the US. I can't find the name of the startup. Conductive silver pastes are traditionally used to make electrical contacts to solar cells. The metal is highly conductive, oxidation resistant, has a moderately low melting point, and does not cause electronic defects in silicon. But the solar industry has grown so much that this single use of silver is estimated to account for a third of all industrial demand in 2024: https://www.silverinstitute.org/wp-content/uploads/2024/04/World-Silver-Survey-2024.pdf https://www.silverinstitute.org/wp-content/uploads/2024/04/W... ("Silver Supply and Demand" table, page 12.) The main alternatives to silver paste are paste made with silver-coated copper, plated silver, and plated base metal stacks (nickel/tin/copper). Plating silver instead of applying it as paste can marginally reduce metal consumption because the plated metal is denser and a better conductor. Plating is slower and typically requires more environmental controls than using conductive paste, so although it has been used commercially for solar cells it has never been as common. Rising silver prices and solar sector consumption could tilt the balance against silver pastes. I don't see how these developments would specifically give the US an advantage against China in solar manufacturing, since reducing consumption of silver reduces material costs wherever the industry is located. EDIT: this appears to have the full WSJ article contents, but I was only able to read it on my first click. After that it redirected me to a login wall on the WSJ: https://www.msn.com/en-us/money/markets/the-solar-breakthrough-that-could-help-the-u-s-compete-with-china/ar-BB1njJbK https://www.msn.com/en-us/money/markets/the-solar-breakthrou... The full article says that the startup is Lumet. Here's their technology page: https://www.lumet.com/technology https://www.lumet.com/technology They are still using conductive silver pastes, but they apply it in narrower lines with higher aspect ratio. They also claim to reduce equipment complexity while improving throughput. So this is a significant evolutionary development of silver paste metallization but does not replace silver or silver pastes.
