Cesium-Triiodide-Mediated Crystallization Regulation of Pure-Iodide Wide-Bandgap Perovskites Enables Perovskite-Silicon Tandem Solar Cells Exceeding 30% Efficiency

Pure-iodide wide-bandgap (WBG) perovskites (∼1.68 eV) featuring eliminated photoinduced halide segregation are compelling top-cell absorbers for perovskite-silicon tandem solar cells. However, their complex crystallization readily induces heterogeneous composition and structural defects, hindering performance improve...

Manipulating Crystallization and Deprotonation Reaction through Surface Engineering of ZnO for Bright and Stable Near-Infrared Perovskite LEDs.

Perovskite light-emitting diodes (LEDs) have attracted significant attention owing to their rapidly increasing external quantum efficiencies (EQEs). However, achieving bright and operationally stable perovskite LEDs remains a great challenge. Here, we reveal that the most commonly used surface modifier of zinc-oxide (Z...

Rationally Designed Cooperative Self‐Assembled Monolayers Enable Holistic Modulations of Wide‐Bandgap Perovskites for High‐Performance Perovskite‐Silicon Tandem Solar Cells

Perovskite‐silicon tandem solar cells hold great promise for the development of next‐generation cost‐effective photovoltaic technologies, and their performance gains largely rely on advanced materials and interface engineering of wide‐bandgap perovskite sub‐cells. Herein, we develop a cooperative self‐assembled monolay...
