Overview

Experimental study demonstrates enhanced light absorption in transition metal dichalcogenide heterostructures, highlighting potential for flexible photovoltaics.

Key Points

  • To develop photoactive two-dimensional heterostructures by combining transition metal dichalcogenides with graphene to enhance light-matter interactions for ultrathin optoelectronics.
  • Fabricated vertical heterostructure stacks combining semiconducting transition metal dichalcogenides (TMDCs) with transparent graphene electrodes.
  • Exploited Van Hove singularities within the TMDC electronic density of states to amplify photon absorption and generate electron-hole pairs.
  • Achieved device photoresponsivity exceeding 0.1 A/W.
  • Demonstrated an external quantum efficiency greater than 30% through efficient charge collection in graphene layers.
