Silver components of photovoltaic panels
The Silver ConnectionConductive Paste The front surface of a solar cell is coated with a thin layer of silver-based conductive paste, such as this conductive silver paste from Targray. Busbars Busbars are conductive strips that collect the electrical current generated by the solar cells and transfer it to the solar panel’s output terminals. Back Contacts .

Pyrolysis and gravimetric separation methods are the most effective, which recovered 91.42 %and 94.25 % silver from crystalline panels and 96.10% silver from CIS PV panels. Yang et al. (2017) used methane sulphonic acid (MSA) with an oxidation agent (hydrogen peroxide) to extract silver from photovoltaic panels.
The cumulative mass of end-of-life (EoL) PV panels is predicted to be 60–78 million tonnes and exceed nearly 10% of the total global electronics waste annually by 2050. Instead of landfills, EoL PV panel recycling, during which valuable materials, e.g., silver, can be recovered, could be environmentally and economically beneficial.
How is silver used in solar cells? Silver powder is turned into a paste which is then loaded onto a silicon wafer. When light strikes the silicon, electrons are set free and the silver – the world’s best conductor – carries the electricity for immediate use or stores it in batteries for later consumption.
The clean energy transition could see the cumulative installed capacity of photovoltaics increase from 1 TW before the end of 2022 to 15–60 TW by 2050, creating a significant silver demand risk. Here, we present a silver learning curve for the photovoltaic industry with a learning rate of 20.3 ± 0.8%.
