Charge Transfer Modulation in Vanadium-Doped WS /Bi O Se Heterostructures.

The field of photovoltaics is revolutionized in recent years by the development of two-dimensional (2D) type-II heterostructures. These heterostructures are made up of two different materials with different electronic properties, which allows for the capture of a broader spectrum of solar energy than traditional photovoltaic devices. In this study, the potential of vanadium (V)-doped WS is investigated, hereafter labeled V-WS , in combination with air-stable Bi O Se for use in high-performance photovoltaic devices.
