摘要：
We report the photovoltaic performance of a diode based on a p-type tungsten diselenide (WSe2) active region. The device is formed by WSe2 and cadmium sulfide (CdS) layers, both obtained via chemical bath deposition. A novel hydrazine-free chemical formulation allows deposition of WSe2 on glass and flexible Hastelloy substrates. Characterization of WSe2 via Raman spectroscopy shows four bands at 189, 244, 293, and 588 cm(-1). The strongest band at 293 cm(-1) is assigned to the interlayer interaction mode of the WSe2 layers. The photoluminescent characterization of Hastelloy/CdS/WSe2 samples exhibits two excitonic transitions at 1.7860 and 1.7899 eV. The current density-voltage (J-V) measurements of the CdS/WSe2 structure show a photovoltaic response with V-OC = 180 mV, J(SC) = 0.07 mA cm(-2), and FF = 0.22.
