Surface Planarization‐Epitaxial Growth Enables Uniform 2D/3D Heterojunctions for Efficient and Stable Perovskite Solar Modules by Dongxu Lin, Jun Fang, Sibo Li, Zhenye Zhan, Huan Li, Xin Wang, Guanshui Xie, Daozeng Wang, Nuanshan Huang, Haichen Peng, Weiguang Xie, Luis K. Ono, Yabing Qi, Longbin Qiu

“…Abstract Two‐dimensional/three‐dimensional (2D/3D) halide perovskite heterojunctions are widely used to improve the efficiency and stability of perovskite solar cells. However, interfacial defects between the 2D and 3D perovskites and the poor coverage of the 2D capping layer still hinder long‐term stability and homogeneous charge extraction. …”
