Abstract

Life cycle analysis becomes especially important for characterizing new material forms in new energy generation technologies intended to replace or improve the current infrastructure of energy production. We propose a comparative life-cycle analysis framework for investigating the effect of introducing nanotechnology in the life cycle of new photovoltaics, which focuses on the differences between the new technologies and the ones that they may replace. The following parameters are investigated within this framework: methods of synthesizing nanoparticles, physicochemical specifications of the precursors, material utilization rates, deposition rates, energy-conversion efficiencies, and lifetime expectancy of the final product. We introduce the application of this framework in comparing nano-structured cadmium telluride and silicon films with their nano- and amorphous- structured equivalents.
