Synergetic Dopant and Additive Engineering of Hole Transporter for Outdoor‐Stable Perovskite Solar Modules

ABSTRACT The spiro‐OMeTAD hole‐transport layer (HTL) underpins high‐performance n–i–p perovskite solar cells (PSCs), but conventional hygroscopic lithium dopants and volatile additives undermine operational stability and complicate module fabrication. Here we introduce a synergis...

Templated growth of phase-pure two-dimensional perovskite for durable solar cells

Abstract 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 iodid...
