Photovoltaics - Reuse, Recycle?

Hi Dr. Pearce,

Having almost zero knowledge of solar PV cells (my sincere apologies) and currently heavily under the influence of CIVL 472: Waste Management, I have a question for you regarding end-of-life use of solar cells.

I understand that the cells are generally guaranteed to last about 20 years and their use can continue beyond that; however, they inevitably will need to be replaced at some point. With such a shift towards renewable energy (and therefore, increased production of solar PV cells), has much thought been given to what will happen once they are no longer fit for their original purpose? Can any parts be reused or recycled? Furthermore, does the production of the cells require 100% raw materials, or can some of the parts be made of recycled materials?

Many thanks,
