N2 - This research evaluates the potential for tin-based materials to displace CdTe as a successive PV technology, due to the wider availability of tin relative to tellurium supplies and processing. The assessment evaluates the long term cost contributions of tin to PV production based on projected refined metal price estimates and mining trends and its potential for sustaining high growth rates. Calculations show that tellurium use in PV as of 2011 constitutes about $0.058/Wp of the manufacturing cost and 20% of the estimated global annual tellurium production. Demand for the refined metal can be expected to increase beyond production levels, thereby questioning the long-term sustainability of the CdTe-based technology for economic PV deployment. It is shown that similar use of tin sulfides in PV would indicate a 0.049/Wp cost advantage and utilize 1% of annual production for 1 GW deployment. Hence, tin has the potential to support not only gigawatt-level demand but also permit cost reductions through technological improvements.
