How much Silver do we need for Solar Panels?

We Answered:

Some research has shown that small amounts of silver can improve the efficiency of solar panels. But this appears to be in the research stage and applies to the the thin film solar cells.

Some solar panels makes use silver as the wiring in kind of a screen printing process, but you don't need to use silver, you can use copper or aluminum using different techniques instead.

Generally the metal used is in small amounts and not a majority of the cost of the solar panel.
