Plasmonic hybrid nanostructures offer more absorption of light in multijunction PV cells. The hybrid plasmonic cells include the earth abundant photoactive layers and cheap plasmonic metal nanoparticles as scattering elements. The organic or inorganic materials can be used as photoactive layer to increase the coupling of sunlight into photoactive material for enhancing light absorption. The hybrid plasmonic solar cell with Ag nanoparticles in TiO₂/benzoic-acid-fullerene bishell (Ag@TiO₂@Pa) has shown conversion efficiency of 20.2%. The enhanced light absorption and carrier extraction of devices are responsible for better performance of PV device [88]. Zhang et al. demonstrated a hybrid plasmonic cell by incorporating silver plasmonic nanoparticles at back side in silicon solar cell and achieved 69% enhancement in photocurrents with light. The plasmonic organic solar cell using Au quantum dots and localized surface plasmons has demonstrated an enhancement in efficiency upto 13% [89].
