Tungsten diselenide (WSe2) has a high absorption coefficient, high light stability and a band gap of 1.2 eV. It is an indirect band gap semiconductor material that can be doped with N-type and P-type at the same time.
The bipolar nature of WSe2 makes it possible to create electronic devices that contain p-n junctions or complementary logic circuits. Transition metal dihalides are semiconductors with potential applications in solar cells and photonics. The WSe2 photoelectrode is stable under both acidic and alkaline conditions, so it can potentially be used in electrochemical solar cells. The mechanically peeled WSe2 single layer is a transparent photovoltaic material with LED characteristics.
