Transfer-printed silver nanodisks for plasmonic light trapping in hydrogenated microcrystalline silicon solar cells

摘要

Plasmonic light trapping is a topic of high interest, but research regarding this topic has been so far impeded owing to the lack of convenient methods to produce desired metal nanostructures in solar cells. To overcome this challenge, we herein introduced a transfer printing approach and performed demonstrative light trapping. Promising results were verified with superstrate-type hydrogenated microcrystalline Si cells fabricated on flat superstates; for example, the photocurrent generated in the 650-1100 nm range increased to up to 60%. Since our transfer printing approach was applicable to textured surfaces, the integration of plasmon-mediated light trapping and front texture-mediated light trapping was also explored.
