The mentioned study and information on components required for solar are very easy to search for if you're interested. I'm in no way against renewables but I wanted to highlight that it's early days for these technologies.
Let me be blunt: I was calling out a lie. Solar does not require rare materials, and you are either misrepresenting the study you are pointing to, or the study is mistaken. If this is the study I am thinking of, you're misrepresenting it.
Silicon PV (which is 95% of the market) uses no rare elements except silver for front contact wires, and that can be substituted for with copper if a diffusion barrier layer is added to prevent its reaction with silicon.
