Sisällysluettelo:
- <p><em>This study presents a fully analytical, performance-normalized evaluation of nano-engineered multilayer radiative composites as substitutes for conventional silicon–polymer photovoltaic module systems. The analysis employs a cradle-to-grave lifecycle framework in which all numerical results are derived from first principles or explicitly referenced literature values. Optical absorption is modeled using spectral integration over the AM1.5 irradiance distribution; operating temperature is obtained by numerically solving a nonlinear steady-state energy balance; and electrical efficiency is coupled to thermal state via a temperature-dependent power coefficient. Material demand and manufacturing energy are derived analytically and scaled to a performance-normalized functional unit of 1 kWh generated under standard test conditions. A Monte Carlo sensitivity analysis quantifies the robustness of results across simultaneously varying uncertain parameters. Techno-economic evaluation integrates material and process energy costs into a unified cost framework. Results indicate that the composite system reduces lifecycle material demand by approximately 40%, manufacturing energy by approximately 70%, and total production cost by approximately 59% relative to the silicon baseline. Sensitivity analysis confirms these advantages are robust across realistic parameter ranges. Limitations, key assumptions, and the experimental validation pathway are discussed in detail. The study establishes a rigorous comparative baseline for environmentally and economically informed material selection in next-generation photovoltaic technologies.</em></p>
