Templated growth of phase-pure two-dimensional perovskite for durable solar cells
The impure phase in typical solution-processed two-dimensional/three-dimensional (2D/3D) perovskite heterostructures limit the performance and stability of perovskite solar cells. We overcome this limitation through a templated growth strategy utilizing excess lead iodide, which directs the formation of robust phase-...
