| Abstract Scope |
Two-dimensional materials such as MoS2 are used as hole transport layer for increasing efficiency of solar cells. Transparent conductive oxides are commonly used as fore contacts in the solar cells. Monolayer MoS2 in contact with AZO has 85% transmittance in the visible region, a low threshold voltage (0.69V) and a large switching ratio (4 × 108). Studying contact of transparent conductive oxide with two-dimensional materials is essential for solar cells applications. Black phosphorus offers unique attributes of both transition metal dichalcogenides and graphene. We will report on chemical vapor deposition grown transition metal dichalcogenides such as MoS2 and WSe2 and mechanically exfoliated black phosphorus that have been transferred onto transparent conductive oxides. In this work, the opto-electronics performance of various transparent conductive oxides in contact with black phosphorus and various transition metal dichalcogenides will be evaluated and its role in improving the efficiency of solar cells will also be studied. |
