Perovskite Quantum Dots for Improvement in Efficiency of Perovskite Solar Cells: Recent Advances and Prospects

Advanced Materials Interfaces, EarlyView.
Quantum dots (QDs) boost perovskite solar cells (PSCs) performance/stability via tunable bandgap, energy alignment, and interfacial engineering. This review covers three frontiers: 1. interfacial defect passivation by Ligand‐engineered QDs in PSCs. 2. QDs multifunctional interlayers via bandgap/energy alignment. 3. QDs in tandem cells.

“Three‐Color” Chemical Selectivity between Oxide, Nitride, and Silicon: Area‐Selective Deposition of Metal Oxide and Polymer on SiN and Si‐H versus SiO2

Advanced Materials Technologies, EarlyView.
Molybdenum hexafluoride as a pretreatment is able to create a chemical contrast between SiN and SiO2 surfaces via selective fluorine passivation of the oxide. One dose of MoF6 enabled 9.7 nm of selective deposited TiO2 on SiN versus SiO2 with selectivity >0.92 on a nanoscale SiN/SiO2 patterned surface.
