Summary: This article reports an elegant method to integrate perovskites and Si-heterojunction tandem solar cells using an ultra-thin indium tin oxide (ITO) interlayer, which overcomes the efficiency limit of single junction solar cells. It is found that a 1.7 nm ITO interlayer provides efficient interfacing between the silicon and perovskite subcells. Thinner ITO interlayers result in discontinuous films, while thicker ITO interlayers are less effective in localizing shunts.

Summary: The work function of nickel oxide (NiOx) hole-injection layers (HILs) is tuned using self-assembled molecules (SAMs). The orientation of the SAMs plays a stronger role in tuning the work function than the intrinsic dipole moment of the molecules. SAMs with nitro group (NO2) show limited work function tuning when parallel to the NiOx surface, while SAMs with trifluoromethyl group exhibit an angled orientation and better activate hole injection without luminescence quenching. The highest external quantum efficiency (EQE) among inorganic HIL-based QLEDs is achieved in InP QLEDs employing inorganic HILs, reaching 18.8%.

Summary: This study explores a method to achieve high efficiency and stability in semiconducting lead halide perovskite nanocrystals (PNCs) through a single processing strategy by finding suitable surface ligands. The PNC ink prepared using this method can be used to fabricate both LED and PV devices, with peak electroluminescence external quantum efficiency of 17.00% and power conversion efficiency of 14.92%. It is found that a careful design of the aromatic rings in the ligands is crucial for achieving high performance, ease of processing, and improved phase stability. This research demonstrates the role of ligand design in PNC ink formulations for high-throughput production of optoelectronic devices and paves the way for dual-mode devices with both PV and LED functionalities.
