Plasmonic Efficiency Enhancement of High Performance Organic Solar Cells with a Nanostructured Rear Electrode

摘要

An essential aspect of reducing the cost of photovoltaic devices lies in enhancing their efficiency without increasing their thickness. To that end, several absorption enhancement strategies have been proposed, including photonic crystals, optical cavities, and plasmonic nanostructures such as metal nanoparticles, gratings, and nanostructured electrodes. By employing metal nanostructures, an efficiency enhancement of Si, Ⅲ-Ⅴ, dye-sensitized, and organic solar cells has been reported.
