Article Abstract
Organolead trihalide perovskite materials have been widely used as light absorbers in efficient photovoltaic cells. Solution engineering is a fast and effective method to fabricate perovskite films. Here, we report a fast precipitation of a pin-hole free perovskite film by small molecule-driven directed diffusion engineering. Solvent molecules diffuse easily and quickly by colliding with small molecules, e.g. helium. Fully compact perovskite films and highly efficient perovskite solar cells are achieved, and the devices show remarkable stability of ca. 90% original efficiency after more than 1000 hours of testing. The small molecule driving directed diffusion offers a promising fast precipitation of a perovskite film and highly efficient, stable perovskite solar cells.

Chiral halide perovskite (c-HP) semiconductors exhibit on average a large chiral-induced spin selectivity (CISS) effect. Nevertheless, the microscopic details of CISS and its integration in opto-spintronic constructs remain nascent. Reliable reporting of CISS performance characteristics represents a significant challenge in providing the necessary design rules.

Achieving UVA/B-selective, skin-inspired nociceptors with perception and blockade functions at the single-unit device level remains challenging. This is because the device necessitates distinct components for every performance metric, thereby leading to complex preparation processes and restricted performance, as well as the absence of deep UV (UVB and below)-selective semiconductors. Here, to address this, we develop a structure-simplification skin-inspired nociceptor using a reverse type-II CuAgSbI/MoS heterostructure.

Perovskite materials have revolutionized optoelectronics by virtue of their tunable bandgaps, exceptional optoelectronic properties, and structural flexibility. Notably, the state-of-the-art performance of perovskite solar cells has reached 27%, making perovskite materials a promising candidate for next-generation photovoltaic technology. Although numerous reviews regarding perovskite materials have been published, the existing reviews generally focus on individual material systems (e.

Polymer additives exhibit unique advantages in suppressing lead leaching from perovskite solar cells (PSCs). However, polymers tend to excessively aggregate in the perovskite film, which hinders comprehensive encapsulation and disrupts charge transport efficiency, degrading lead leakage inhibition and device performance. Herein, a polymer dynamic soft encapsulation strategy driven by molecular extrusion is introduced to mitigate lead leakage in PSCs, achieved through the incorporation of poly(propylene adipate) (PPA) as a multifunctional additive in the perovskite formulation.

Circularly polarized luminescence (CPL) has emerged as a critical technology for anticounterfeiting and optical display applications due to its unique chiroptical properties. We report a multicolor CPL-emitting elastomeric film (P37/PSK@SiO-PDMS) that synergistically combines chiral helical polyacetylene (P37) and a surface-engineered perovskite (PSK@SiO) through hydrogen-bond-directed assembly. Confinement within the PDMS matrix drives P37 to self-assemble into a chiral supramolecular structure through hydrogen bonding, inducing a chiroptical inversion.
