Highly Efficient and Stable 2D Dion Jacobson/3D Perovskite Heterojunction Solar Cells

Mohammad Khaja Nazeeruddin, Pankaj Kumar Yadav

Heterostructures involving two-dimensional/three-dimensional (2D/3D) perovskites have recently attracted increased attention due to their ability to combine the high photovoltaic performance of 3D perovskites with the increased stability of 2D perovskites. ...
