The front contacts in today’s solar cells are made of screen-printed silver. Thus solar cells absorbed 11% of 2021’s silver market, and growing. Silver can be substituted with copper. But…

…more materials becomes harder. Unfortunately solar panels do not grow on trees. Building more solar requires building more PV silicon, or silver, or copper production facilities. These are also capital…
