I spoke to Sebastian Stäter, PhD student in Experimental Physics at the University of Groningen, about the need for crude oil to create plastics and whether there were greener alternatives.

Sebastian shared some good news that may be of interest to @Factotum , @CadeJohnson and others:

“Note however that we don't need much of these materials: Assuming a typical device thickness of 100nm (!), you could get ten thousand square meters of solar cell panels out of one liter polymer material.” [1]
