- Microcavity-Enhanced Light-Trapping for Highly Efficient Organic Parallel Tandem Solar Cells
Lijian Zuo, Chu-Chen Chueh, Yun-Xiang Xu, Kung-Shih Chen, Yue Zang, Chang-Zhi Li, Hongzheng Chen and Alex K.-Y. Jen
Article first published online: 28 AUG 2014 | DOI: 10.1002/adma.201402782
A high-performance parallel tandem solar cell employing ultra-thin Ag as the intermediate anode is demonstrated, which comprises a semitransparent front sub-cell and a microcavity assisted back sub-cell. In addition to the extended optical field as a result of the tandem architecture, the prominent microcavity resonance formed in the back sub-cell enables such parallel tandem configuration to possess high light utilization efficiency (the peak EQE value is over 80%) and high photovoltaic performance of 9.2%. This study establishes an effective architecture that can be generally applicable to all organic materials for improving their performance.

A minimally invasive, highly efficient and versatile strategy is proposed for localized tumor regression by developing a smart injectable liquid-solid phase-transformation organic-inorganic hybrid composite material, i.e., magnetic Fe powder-dispersed PLGA (Fe/PLGA) implants formagnetic-hyperthermiatherapy of cancer.
- Back Gated Multilayer InSe Transistors with Enhanced Carrier Mobilities via the Suppression of Carrier Scattering from a Dielectric Interface
Wei Feng, Wei Zheng, Wenwu Cao and PingAn Hu
Article first published online: 28 AUG 2014 | DOI: 10.1002/adma.201402427
The back gate multilayer InSe FETs exhibit ultrahigh carrier mobilities, surpassing all the reported layer semiconductor based electronics with the same device configuration, which is achieved by the suppression of the carrier scattering from interfacial coulomb impurities or surface polar phonons at the interface of an oxidized dielectric substrate. The room-temperature mobilities of multilayer InSe transistors increase from 64 cm2V−1s−1 to 1055 cm2V−1s−1 using a bilayer dielectric of poly-(methyl methacrylate) (PMMA)/Al2O3. The transistors also have high current on/off ratios of 1 × 108, low standby power dissipation, and robust current saturation in a broad voltage range.
- Exploring Actinide Materials Through Synchrotron Radiation Techniques

Article first published online: 28 AUG 2014 | DOI: 10.1002/adma.201304323
The rapid development of synchrotron radiation (SR) based techniques offers tremendous opportunities for brilliant and challenging research in actinide-based materials nowadays. This review addresses recent research progresses in actinide related materials by means of various SR techniques, with emphasis on X-ray absorption spectroscopy, X-ray diffraction and scattering spectroscopy.
- Highly Reversible and Large Lithium Storage in Mesoporous Si/C Nanocomposite Anodes with Silicon Nanoparticles Embedded in a Carbon Framework
Renyuan Zhang, Yuanjin Du, Dan Li, Dengke Shen, Jianping Yang, Zaiping Guo, Hua Kun Liu, Ahmed A. Elzatahry and Dongyuan Zhao
Article first published online: 28 AUG 2014 | DOI: 10.1002/adma.201402813
A magnesiothermic reduction approach is designed to synthesize mesoporous Si/C nanocomposites with ultrasmall, uniform silicon nanoparticles (ca. 3 nm) embedded in a rigid mesoporous carbon framework. The resultant mesoporous Si/C nanocomposites present excellent performance with high reversible capacity, good coulombic efficiency and rate capability, and outstanding cycling stability in lithium-ion battery applications.
