Development of ZnO Buffer Layers for As‐Doped CdSeTe/CdTe Solar Cells with Efficiency Exceeding 20%

open access: yesAdvanced Materials Technologies, EarlyView.
Highly resistive ZnO has been used as the buffer layer in As‐doped CdSeTe/CdTe solar cells to achieve efficiencies higher than 20%. STEM images and EDX mapping show that the quality of the front interface is dependent on the ZnO deposition temperature. Unusually, chlorine is not observed at the front interface using EDX when the ZnO is deposited at 100

Design of a Simple and Rugged Soft Polydimethylsiloxane‐Carbon Nanotube‐Graphene‐Based Composite Sensor

open access: yesAdvanced Materials Technologies, EarlyView.
This research presents an easy to fabricate, low‐cost, flexible piezoresistive deformation sensor comprised of a carbon nanotube, few‐layer graphene, and polydimethylsiloxane composite. The sensor detects deformations and vibrations up to 600 Hz with 0.1% strain sensitivity from stiff and soft targets in dry and wet environments.

Electrical Metamaterial‐Based Interconnects‐Enabled Highly Stretchable Wireless Electrocardiography Circuit

open access: yesAdvanced Materials Technologies, EarlyView.
This article presents a novel strategy for creating highly stretchable wireless circuits using electrical metamaterial‐based interconnects (EMIs). Embedded in soft polymers and filled with liquid metal, EMIs uniquely reduce resistance under strain. A fully integrated ECG circuit demonstrates reliable performance under 100% stretch, offering a highly ...
