Molecular ferroelectric self-assembled interlayer for efficient perovskite solar cells.

The interfacial molecular dipole enhances the photovoltaic performance of perovskite solar cells (PSCs) by facilitating improved charge extraction. However, conventional self-assembled monolayers (SAMs) face challenges like inadequate interface coverage and weak dipole interactions. Herein, we develop a strategy using a self-assembled ferroelectric layer to modify the interfacial properties of PSCs.

Oriented wide-bandgap perovskites for monolithic silicon-based tandems with over 1000 hours operational stability.

The instability of hybrid wide-bandgap (WBG) perovskite materials (with bandgap larger than 1.68 eV) still stands out as a major constraint for the commercialization of perovskite/silicon tandem photovoltaics, yet its correlation with the facet properties of WBG perovskites has not been revealed. Herein, we combine experiments and theoretical calculations to comprehensively understand the facet-dependent instability of WBG perovskites.

Comparative Outcomes Between Surgical and Conservative Management of Mallet Thumb: A Systematic Review and Pooled Analysis.

Background: While mallet finger remains a relatively common injury of the hand, mallet thumb is much rarer in occurrence. Mallet thumb management has been noted infrequently within the literature and reliable evidence regarding the most effective method of management remains absent. The aim of this review is to assess the quality of literature that exists pertaining to mallet thumb to determine whether conservative or surgical management is superior.
