Design Optimization of Cesium Contents for Mixed Cation MA1−xCsxPbI3-Based Efficient Perovskite Solar Cell
Published on 2025-07-13 by Syed Abdul Moiz, Ahmed N. M. Alahmadi, Mohammed Saleh Alshaikh @MDPI
Abstract: Perovskite solar cells (PSCs) have already been reported as a promising alternative to traditional energy sources due to their excellent power conversion efficiency, affordability, and versatility, which is particularly relevant considering the growing worldwide demand for energy and increasing scarcity of natural resources. However, operational concerns under environmental stresses hinder its economic feasibility. Through the addition of cesium (Cs), this study investigates how to optimize pero[...]
Our summary: Study investigates optimizing perovskite solar cells with mixed-cation compositions of MA1−xCsxPbI3, finding that MA0.5Cs0.5PbI3 achieves maximum efficiency of 18.53% with Cs doping. Optimal device architecture and layer thicknesses are identified for improved performance.

Monolithically Integrated GaAs Nanoislands on CMOS-Compatible Si Nanotips Using GS-MBE
Published on 2025-07-12 by Adriana Rodrigues, Anagha Kamath, Hannah-Sophie Illner, Navid Kafi, Oliver Skibitzki, Martin Schmidbauer, Fariba Hatami @MDPI
Abstract: The monolithic integration of III-V semiconductors with silicon (Si) is a critical step toward advancing optoelectronic and photonic devices. In this work, we present GaAs nanoheteroepitaxy (NHE) on Si nanotips using gas-source molecular beam epitaxy (GS-MBE). We discuss the selective growth of fully relaxed GaAs nanoislands on complementary metal oxide semiconductor (CMOS)-compatible Si(001) nanotip wafers. Nanotip wafers were fabricated using a state-of-the-art 0.13 μm SiGe Bipolar [...]
Our summary: Monolithic integration of GaAs nanoislands on Si nanotips using GS-MBE enables advancement of optoelectronic devices. Selective growth of fully relaxed GaAs islands on CMOS-compatible Si(001) nanotip wafers. Investigation focuses on growth conditions influence on morphology, crystalline structure, and defect formation.

Chiral Recognition of Carnitine Enantiomers Using Graphene Oxide-Modified Cadmium Telluride Quantum Dots
Published on 2025-07-08 by Haiyan Yuan, Yu Ma, Yuhui Zhang, Jidong Yang, Zhiyuan Mei, Chengcheng Pi, Yuan Peng @MDPI
Abstract: Carnitine (CA) is a chiral amino acid and mostly comes from meat and dairy products. CA cannot be found in fruits, vegetables, or other plants, so vegetarians are deficient in CA. CA exists in the form of D-carnitine (D-CA) and L-carnitine (L-CA); only L-carnitine has biological activity. L-CA promotes the oxidation of fatty acids and then causes the effect of weight loss. In this study, the fluorescence probe was established by using graphene oxide-modified cadmium telluride (CdTe) QDs (GO-CdTe[...]
Our summary: Chiral amino acid carnitine comes from meat and dairy, not fruits or vegetables. L-carnitine promotes weight loss by oxidizing fatty acids. Graphene oxide-modified cadmium telluride quantum dots used for chiral recognition of carnitine enantiomers.
