How Do Plasmonic Nanostructures Enhance Solar Cell Efficiency?
Plasmonic nanostructures enhance solar cell efficiency through several mechanisms. The primary mechanism is the localized surface plasmon resonance (LSPR), where incident light induces collective oscillations of free electrons in the metal nanoparticles. This phenomenon leads to strong light scattering and concentration near the nanoparticles, thereby increasing the absorption of light within the active layer of the solar cell.
