Are you sure Silver is used in solar panels ? That is HUGE BUSINESS now worldwide.
yes 100% sure:
The average solar panel actually uses about two-thirds of an ounce of silver, which is about 20 grams. That might not sound like a lot, but at around $20 an ounce it contributes more to the cost of solar than it does to the other industrial products that use silver.
And that's just one of its uses. The battery market may be at least as big as the solar panels.
According to Ortega, when silver-zinc is compared with the smallest Li-ion batteries available, the silver-zinc cell has a 57-percent greater energy density, whereas the largest silver-zinc cell is greater by 20 percent over the best performing Li-ion option available. He also said silver-zinc rechargeable microbatteries have been shown to be safer and better for the environment.
I actually have a silver-calcium battery in the car right now.
