Det spås stort ökat behov av silver för solceller

Både för nuvarande teknik och ny teknik som ger ökad verkningsgrad.
Då silver har den lägsta resistiviteten är det oersättligt för att uppnå högsta verkningsgrad i nyutvecklade tekniker.

Utdrag ur artikeln:
The second factor that could blow current silver demand projections out of the water is changes to the solar cells themselves. The predominant solar panel technology in use today is the passivated emitter and rear contact (PERC) cell, but this design is being replaced by two newer and more efficient technologies: tunnel oxide passivated contact (TOPCon) and heterojunction structures (HJT).

This additional efficiency comes at the cost of additional silver; while PERC cells use around 10 milligrams of silver per watt, TOPCon cells need 13 milligrams, and HJT uses as much as 22 milligrams per watt.

Krauth said the industry is quickly pivoting to these newer technologies. “In 2023, 80% of all new solar panel production will be those two technologies,” he said. “As manufacturers produce additional capacity, they're going to be investing, 80% of this new capacity will be these two new technologies, which require 50 to 150 percent more silver.”

Är det 11% av allt silver som bryts som blir solpaneler idag?

“Solar alone is 12 percent of all silver demand every year, that was 140 million ounces last year,” Krauth said. “The forecasts are about 160 million ounces this year, which I believe are going to be dramatically outpaced when we see the final numbers about a year from now.”

Nu när har vi facit för 2023 så.överträffade det prognoserna markant.
64% till 193,5 miljoner oz blev ökningen!
För 2024 spås ökningen nu bli 20%……

”The Silver Institute says global silver demand in 2023 exceeded available supply
Solar PV industry demand grew by 64% annually as it led total demand from industrial applications
In 2024, the PV demand is likely to grow by 20% annually as installation spree slows down
The global demand for silver continued to rise in 2023, making it the 3rd consecutive year when demand exceeded the supply, says The Silver Institute. The silver demand from the solar PV industry increased 64% annually, surpassing estimates. ”
