Unleashing the Potential of Raman Spectroscopy to Estimate PEDOT:PSS Doping Level and Crystalline Morphology

open access: yesAdvanced Science, EarlyView.
Herein, the correlational changes of each PEDOT Raman peak to morphology and doping level are identified. Two equations are derived to estimate PEDOT π–π spacing and doping level from Raman spectra (from which mobility is also extracted). GIWAXS and XPS results validate the estimation equations.

Alkylthienyl Side Groups in Conjugated Polymers Enable Localization of π Electron Density and Facilitate Efficient Hole Transfer

open access: yesAdvanced Science, EarlyView.
Resonance Raman spectroscopy is used in combination with other spectroscopic and morphology characterization techniques to unveil the mechanistic origin of the shift in synthetic strategy to alkylthienyl peripheral groups for high‐performing organic photovoltaics.

Perspective: Hollow Core Optical Fibres for Ultraviolet and Visible Wavelengths

open access: yesAdvanced Science, EarlyView.
Hollow core optical fibres bypass material constraints that limit optical fibres at ultraviolet and visible wavelengths. However, their challenging fabrication has limited their development, and significant gains in performance remain possible. In this perspective we outline approaches to enable the next generation of fibres for shorter wavelengths ...

Thermodynamically Reinforced Dual‐Interface 1D/3D Tin‐Lead Perovskite Heterostructure for Stable All‐Perovskite Tandem Solar Cells

open access: yesAdvanced Science, EarlyView.
A π‐conjugated diammonium additive is employed to engineer a dual‐interface 1D/3D perovskite heterostructure. π‐π stacking 1D perovskitoids act as nucleation templates to relieve tensile strain and intra‐/intergranular disorder and then encapsulate the 3D bulk to fortify the Sn‐I octahedral framework. The all‐perovskite tandem devices based 1D/3D Sn‐Pb
