Plasmonic solar cells are a class of photovoltaic devices that convert light into electricity by using plasmons. Plasmonic solar cells are a type of thin film solar cell which are typically 1-2μm thick. They can use substrates which are cheaper than silicon, such as glass, plastic or steel. The biggest problem for thin film solar cells is that they don’t absorb as much light as thicker solar cells. Methods for trapping light are crucial in order to make thin film solar cells viable. Plasmonic cells improve absorption by scattering light using metal nanoparticles excited at their surface plasmon resonance. 〔K. R. Catchpole and A. Polman, "Plasmonic solar cells," Opt. Express 16, 21793-21800 (2008) http://www.opticsinfobase.org/oe/abstract.cfm?URI=oe-16-26-21793〕 This allows light to be absorbed more directly without the relatively thick additional layer required in other types of thin-film solar cells. == History ==
