Fig. 7: Sensitivity analysis of various parameters on cumulative energy demand, global warming potential, carbon emission factor, energy payback time, and energy return on investment estimations.

The sensitivity analysis includes: (a) manufacturing supply chain structure (number of representative trading partners) and wafer manufacturing parameters on cumulative energy demand (CED) and global warming potential (GWP), (b) solar irradiation, performance ratio, module efficiency, lifetime, and grid efficiency on energy payback time (EPBT), carbon emission factor, and energy return on investment (EROI).
