Plasmonic back reflector for high-efficiency thin-film silicon solar cells
In this contribution,plasmonic back reflector (BR) with self-assembled Ag nanoparticles (NPs) has been developed for high-efficiency hydrogenated amorphous silicon (a-Si:H) solar cells.The light trapping capability of the plasmonic BR is comparable to the state-of-the-art random textured substrates.The plasmonic back reflector provides a high degree of light trapping,with a haze in reflection greater than 80% throughout the wavelength range 520-1100 nm,although plasmonic back reflector has flattened surface feature with a rms roughness of only 22 nm.A gain of 2 mA/cm2 is achieved compared to the flat device,and the efficiency increases from 6.3% to 8.4%.
