Abstract

Solar cells as a light-electricity conversion device light absorption plays crucial role towards their high performance conversion Incorporation of plasmonic nanostructures with semiconductor materials offer great potential to improve the conversion efficiency of solar cells with much reduced material usage So developing low-cost and large-scale plasmonic nanostructures integratable with solar cells promises new solutions for high efficiency and low cost solar energy Metal nanoparticles can improve the performance of solar cells by plasmonic scattering enhancement and plasmonic near field enhancement Further the localized absorption of metal nanoparticles via surface plasmon resonance has attracted great attention because of large electromagnetic field enhancement the wavelength selective photon absorption and the adjustable resonance wavelength with the changing material size period and dielectric environment of metallic nanoparticles This work highlight the progress made towards efficient plasmionic solar cells
