New research from UNSW in Australia outlines the need for solar cell and module makers to reduce or eliminate the use of silver in their products. Based on expected PV growth, in line with climate change commitments, solar manufacturers would require at least 85% of global silver reserves, according to the new study.

Today, the use of lead is severely restricted, and banned for certain applications where it can not practically be prevented from leaking into the environment, in jurisdictions including the United States, European Union and Japan. In spite of this, a typical 60-cell crystalline silicon solar module produced today contains up to 12 grams of lead.

He had an idea to make solar panels cheaper by using copper instead of silver to absorb power. For various reasons, using copper instead of silver proved to be wise. Copper is 100 times less expensive than silver, a scarce and expensive metal. It also has a far greater supply and requires lower processing temperatures, resulting in less energy use.
Despite these efforts, the recovery of silver (Ag), a crucial and valuable element in the PV modules, is often overlooked, due to its low concentration. Nonetheless, it is a fast depleting resource with limited natural ore deposits. The aim of this review is to present various methods developed for extracting Ag from EoL solar modules.
