Random Micro-Pyramids for Transparent c-Si Solar Cells: Enabling 16.1% Efficiency with Wavelength-Independent 20% Transmittance. [PDF]

open access: yesSmall
Crystalline silicon TPVs excel in transparency, efficiency, and stability, but suffer light loss in transparent regions. This study enhances light absorption by forming random micro‐pyramids on the surface through simple wet etching, boosting JSC to 33.3 mA cm−2 and 16.1% record‐high efficiency for 25 cm2 neutral‐colored TPVs (20% AVT), demonstrating a

Magnetically Driven Spinodal Decomposition as the Origin of Magnetic Softness of CoFeNi-Based Ferromagnetic High-Entropy Alloys. [PDF]

open access: yesChemphyschem
Many CoFeNi‐based high‐entropy alloys are soft ferromagnets. Magnetic softness originates from nanostructure formed by spinodal decomposition, where CoFeNi FM nanodomains alternate with nanodomains of other elements. Spinodal decomposition is magnetically driven via the magnetic part of the Gibbs free energy, where the CoFeNi short‐range FM order ...

Quasi-Transient Calculation of Czochralski Growth of Ge Crystals Using the Software Elmer

open access: yesCrystals, 2019
A numerical scheme was developed to compute the thermal and stress fields of the Czochralski process in a quasi-time dependent mode. The growth velocity was computed from the geometrical changes in melt and crystal due to pulling for every stage, for ...

Inside the Microreactor: In Situ Real-Time Observation of Vapor-Liquid-Solid Growth of Monolayer TMDCs. [PDF]

open access: yesAdv Sci (Weinh)
In situ observation of VLS growth in a confined microreactor reveals various growth modes of monolayer TMDCs, including abnormal ribbon growth and particle‐driven growth. The confined space and precursor balance influence droplet behavior and growth dynamics, offering new insights into the controlled synthesis of TMDCs via the VLS mechanism.

THE CZOCHRALSKI METHOD (CZ): HISTORY AND DEVELOPMENT

open access: yesIzvestiya Vysshikh Uchebnykh Zavedenii. Materialy Elektronnoi Tekhniki = Materials of Electronics Engineering, 2018
60 years ago, in July, 1956, the USSR’s first industrial germanium single crystal was grown up by the Czochralski (CZ) method. The method of growing single crystals according to Czochralski is the most widespread one currently used for obtaining bulk single crystals. The high technical implementation level and the high extent of process automation make
