Which elements are you thinking of? The vast majority of PV being made today is silicon. The only rare element used in PV is silver for front contact wires, and that can be substituted for with proper design (copper wires can be used if a diffusion barrier layer of nickel or molybdenum is used to prevent its reaction with silicon.)
