Additive‐Driven Phase Control for Stable and Efficient CsPbI₃ Solar Cells Via Ambient Low‐Temperature Processing

open access: yesAdvanced Functional Materials, EarlyView.
CsPbI₃ perovskite solar cells face stability issues due to high annealing temperatures and moisture. Butylammonium acetate (BAAc) enables stable phase formation at 160°C in ambient laboratory conditions, enhancing efficiency and stability, achieving 18.6% PCE, and maintaining over 81% efficiency after 1,000 hours of maximum power point tracking under 1

Ultrafast bridge planarization in donor-π-acceptor copolymers drives intramolecular charge transfer

open access: yesNature Communications, 2017
Tracking and understanding charge transfer process is central yet challenging to designing efficient organic photovoltaics. Roy et al. monitor real-time structural changes in donor-π-acceptor polymer backbone, and enumerate the role of π-bridge torsions ...

Microstructural Evolution Dominates the Changes in the Thermal Conductivity of Conjugated Polymers Upon Doping

open access: yesAdvanced Functional Materials, EarlyView.
The relationship between the doping induced microstructure and thermal conductivity changes is elucidated for conjugated polymers. Eight conjugated polymers with different doping systems are studied, showing varied thermal conductivity responses based on structural order.

Colloidal Opaline Composites as Throughput‐Scalable, Fully Transparent, and Color‐Tunable Radiative Cooling Exterior Films for Outdoor Photovoltaics

open access: yesAdvanced Functional Materials, EarlyView.
Particular thermal metamaterials are widely used as daytime radiative coolers merely by embedding thermally emissive nanoparticles (NPs) in liquid resins to form scalable, yet highly efficient cooling films in a cost‐effective way. However, randomly dispersed NPs, prevalently used thus far, cause strong scattering, limiting NP content and cooling ...

Contact Transfer Epitaxy of Halide Perovskites

open access: yesAdvanced Materials, EarlyView.
Bringing a halide perovskite thin film (donor) into contact with a self‐assembled monolayer of oriented perovskite nanocrystals (acceptor) at elevated temperature leads to epitaxial transfer of halide perovskite from the donor to the acceptor substrate.
