Advanced Science, EarlyView.A high‐dielectric niobium oxide (NbOX) electron‐selective contact is introduced to modulate the perovskite/C60 interface in perovskite/silicon tandem solar cells. By shrinking the defect capture radius and chemically passivating Pb‐related defects, NbOX extends carrier diffusion length and optimizes energy‐level alignment, enabling both high efficiency

Study of ohmic contact at Ti/ZnO interface by using electrical characteristics and KPFM analysis
Discover MaterialsAbstract In this paper, a negative barrier height at the interface of ZnO/Ti was studied using Kelvin probe force microscopy (KPFM) analysis. This result agrees with the metal-semiconductor Ohmic contact theory. Without any dopant, the pure ZnO thin films were deposited over integrated circuit compatible SiO2/p-Si silicon by the radio ...

Advanced Science, EarlyView.A synergistic methanol and oxalic acid interface engineering strategy is developed for PbS quantum dot solar cells. This approach transforms the PEDOT:PSS layer into a dense, electronically uniform, and conductive network. Consequently, the device achieves a record‐low voltage deficit of 340 mV, yielding a remarkable Voc of 742 mV and a power ...

Photochemical N‐dealkylation of Tertiary Amines Coupled With Photocharging of Poly(Heptazine Imides)
Angewandte Chemie, EarlyView.Protonated poly(heptazine imide) (H‐PHI) functions as an energy reservoir, thereby facilitating the endothermic dealkylation of triethylamine through a proton‐coupled two‐electron transfer (PC2ET) process. The extent of photocharging is quantitatively described by a molecular‐level descriptor, Ne:Nhept, providing a direct correlation between stored ...

Ag Nanowire‐Integrated MoS2/ZnO Heterojunctions for Highly Efficient Photogenerated Charge Transfer
Advanced Electronic Materials, Volume 11, Issue 6, May 2025.A versatile strategy is reported for fabricating multi‐dimensional heterojunctions with significantly improved charge transfer capability. By integrating Ag nanowires with a MoS2/ZnO heterojunction, a fourfold increase in surface photovoltage is achieved, reaching 200 mV under visible light illumination.
