Abstract

Transition metal dichalcogenides such as MoS2 and WSe2 are excellent candidates for the development of ultrathin solar cells due to their layered crystalline structure and their extremely high light absorption coefficients. In this talk we review the technological challenges associated with the fabrication of solar cells based on quasi 2D-crystals of MoS2 (crystals with thickness between ∼ 5 and 100 nm). We show that it is possible to achieve a large open-circuit voltage (∼ 1 V) in MoS2 homojunction devices under concentrated light and discuss the impact of surface effects, contact technology, and optical design. In the last part of the presentation we talk about the potential use of this emerging technology for the fabrication of semitransparent power-generating windows.
