Abstract: A device and a photovoltaic device, both of which include a 3D perovskite layer and an organic 2D perovskite layer operationally connected to the 3D perovskite layer and defining a heterojunction interface. The photovoltaic device further includes an electrode layer, a hole transport layer operationally connected to and sandwiched between the electrode layer and the organic 2D perovskite layer, a substrate layer, and a tin oxide layer operationally connected to and sandwiched between the substrate layer and the 3D perovskite layer. Also provided is a method of making the photovoltaic device.
