![]() ![]() The present work opens a new avenue for designing 2D/3D perovskite heterojunction and improve the performance and stability of PSCs.So, you’ve decided you want to get into 3D printing? I’m collecting information on this page to help get you started. Simultaneously, the improved device retains 90% of initial performance after aging for 1000 h in ambient conditions. ![]() As a result, a champion power conversion efficiency (PCE) of 15.63% is achieved for the carbon-based hole-transport-layer-free PSCs based on 2D/3D heterojunction, which is higher than that of 11.88% for the control 3D device. A broad range of experimental characterizations exhibit that the introduction of 2D perovskite improve the energy level alignment with adjacent carbon electrode and enhance the hydrophobic property of the perovskite sample. ![]() The relevant growth process, light absorption ability, energy level regulation and stability property of the samples are systematically investigated. Herein, a 2D perovskite with a spacer cation of 1, 4-dimethylphenylene ammonium is grown on 3D perovskite film by the solid-state heat-pressure method. However, it is difficult to fabricate 2D/3D perovskite heterojunction with accurate composition and structure through only solution process, and the location of 2D perovskite is also difficult to regulated owing to the uncontrolled cation exchange between organic constituents, which results in mismatched energy level arrangements. ![]() Formation of a two-dimensional (2D) perovskite layer on the top of three-dimensional (3D) perovskite has been demonstrated to be effective in reducing interfacial charge recombination and improving the performance and stability of perovskite solar cells (PSCs). ![]()
