    Area of Science:

    • Materials Science
    • Condensed Matter Physics
    • Nanotechnology

    Background:

    • Two-dimensional (2D) materials, including graphene, phosphorene, and transition metal dichalcogenides (TMDCs), are integral to modern photovoltaic device design.
    • TMDCs, despite their atomic thinness, offer high light absorption, making them suitable for solar absorptive heterostructures.

    Purpose of the Study:

    • To identify efficient TMDC contacts for maximizing photocurrent generation in photovoltaic devices.
    • To investigate the underlying physics of external quantum efficiency (EQE) and internal quantum efficiency (IQE) in atomically thin (AT) TMDC heterostructures under solar spectrum illumination.

    Main Methods:

    • Detailed examination of EQEs in various AT TMDC heterostructures.
    • Analysis of the correlation between TMDC material absorption, electronic structure gradients at interfaces, and photocurrent generation efficiency.
    • Evaluation of TMDC multilayers for enhanced light absorption and EQE.

    Main Results:

    • Photocurrent generation efficiency is primarily governed by the absorption of constituent TMDCs and the electronic structure gradient at their contact.
    • A WSe2/MoSe2 contact achieved a notable EQE of 0.5% and IQE of 1.4% at 433 nm.
    • While multilayer TMDCs generally increase EQE due to enhanced light absorption, the overall efficiency trend is non-monotonic due to competing factors like electronic structure gradients.

    Conclusions:

    • TMDC-based heterostructures offer a novel pathway for developing efficient and miniaturized optoelectronic devices.
    • Understanding the interplay between absorption and electronic properties is crucial for optimizing TMDC photovoltaic performance.
