Question:

The thickness of the germanium (density 5.32 gm/c m 3) layer in a triple-junction PV is typically greater than 100 microns. If the overall cell efficiency is 40%, how many watts of PV capacity (nominal insolation of 1000 W/m2) could be manufactured from the world’s annual germanium production (165 t in 2014)?
