Resource efficient plasmon-based 2D-photovoltaics with reflective support.

Van der Waals Materials for Atomically-Thin Photovoltaics: Promise and Outlook

Two-dimensional (2D) semiconductors provide a unique opportunity for optoelectronics due to their layered atomic structure, electronic and optical properties. To date, a majority of the application-oriented research in this field has been focused on fieldeffect electronics as well as photodetectors and light emitting diodes. Here we present a perspective on the use of 2D semiconductors for phot...

Metallic Nanoparticles Coupled with Photosynthetic Complexes

Plasmon excitations in metallic nanoparticles provide an efficient way to manipulate electromagnetic fields at the nanoscale (Maier, 2004). While the interactions between plasmons and simple nanostructures such as organic dyes or semiconductor nanocrystals is relatively well described and understood, application of metallic nanoparticles to multipigment structures has started just recently (Car...

Plasmon-enhanced internal photoemission for photovoltaics: Theoretical efficiency limits

Surface plasmon-enhanced nanopillar photodetectors.

We demonstrate nanopillar-(NP) based plasmon-enhanced photodetectors (NP-PEPDs) operating in the near-infrared spectral regime. A novel fabrication technique produces subwavelength elongated nanoholes in a metal surface self-aligned to patterned NP arrays that acts as a 2D plasmonic crystal. Surface plasmon Polariton Bloch waves (SPP-BWs) are excited by the metal nanohole array resulting in ele...

Optical and electrical study of organic solar cells with a 2D grating anode.

We investigate both optical and electrical properties of organic solar cells (OSCs) incorporating 2D periodic metallic back grating as an anode. Using a unified finite-difference approach, the multiphysics modeling framework for plasmonic OSCs is established to seamlessly connect the photon absorption with carrier transport and collection by solving the Maxwell's equations and semiconductor equ...
