Using passive cooling strategies to improve thermal performance and reduce energy consumption of residential buildings in U.A.E. buildings

Frontiers of Architectural Research, 2014
Passive design responds to local climate and site conditions in order to maximise the comfort and health of building users while minimising energy use. The key to designing a passive building is to take best advantage of the local climate.

Charge Generation and Recombination Pathways in All‐Polymer Bulk Heterojunction Solar Cells

Advanced Functional Materials, EarlyView.
Multimodal spectroscopy and device analysis reveal how field‐dependent charge generation, transport limitations, and non‐geminate recombination govern performance losses in all polymer solar cells. The results identify the key processes controlling charge extraction and recombination, providing insights for the design of more efficient all‐polymer ...

High‐Performance n‐Type Organic Thermoelectrics Enabled by Control Over Microstructure, Orientation and Contact Plane in Naphthalenediimide‐Bithiazole‐Copolymer Films

Advanced Functional Materials, EarlyView.
Effective control over the crystalline contact plane and microstructure of a naphthalenediimide‐bithiazole copolymer enables high‐performance n‐type thermoelectrics. While rubbing alignment induces a detrimental edge‐on orientation, subsequent solvent vapor‐induced re‐orientation facilitates a favorable mixed face‐on/edge‐on morphology.

Intrinsic Interfacial Energy Alignment Enables ETL‐Free Organic Solar Cells

Advanced Functional Materials, EarlyView.
Molecular orientation of the small‐molecule donor BTR‐Cl induces a vacuum‐level shift that pins the Fermi level at ∼4.4 eV at the active layer/Ag interface, enabling Ohmic contact formation without an electron transport layer. This strategy is extended to ternary PM6:Y6:BTR‐Cl devices, achieving an ETL‐free efficiency of 18.6% with enhanced operational
