Interfacial Dipole Engineering With Taurine‐Modified SnO2 Electron Transport Layer for Efficient and Stable Perovskite Solar Cells

Rare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT Organic‐inorganic metal halide perovskite solar cells (PSCs) are promising for photovoltaics due to their excellent optoelectronic properties. However, achieving high efficiency and stability remains challenging, mainly due to defects and energy losses at the electron transport layer (ETL)/perovskite interface.

Epitaxial Interface‐Driven Photoresponse Enhancement in Monolayer WS2–MoS2 Lateral Heterostructures

Advanced Functional Materials, Volume 36, Issue 8, 26 January 2026.
Surface potential distribution image, along with the derived electric field distribution across the interface, reveals that the electric field reaches its peak at the interface. Additionally, the spectral response of the heterointerface exhibits higher and broader features compared to its bare counterparts.
