Back-contacted back-junction silicon solar cells

open access: yes, 2011
Conventional silicon solar cells have a front-side contacted emitter. Back-contacted back-junction (BC-BJ) silicon solar cells, on the other hand, have both the complete metallization and the active diffused regions of both polarities on the backside.

The ability to achieve back-to-back wing contact at 20, 29, 42, and 55 days of age.

open access: yes, 2018
Four of 10 unaffected birds (No. 12, 16, 18, and 20) lost their ability of back-to-back wing contact during late stage of rearing. In contrast, 2 of 6 affected birds (No. 3 and 7) recovered its ability of back-to-back wing contact.

Enhancing Bubble Removal in Geometry‐Optimized Electrodes

open access: yesAdvanced Engineering Materials, EarlyView.
3D‐printed lattice electrodes outperform stochastic foams in alkaline water electrolysis despite 20%–25% lower surface area. Straight flow channels generate Venturi‐like bubble entrainment, suppressing gas accumulation that renders foam interiors electrochemically inactive.

Microstructure Reconstruction in Battery Electrodes Using Machine Learning Based on Low‐Voltage Focused Ion Beam–Scanning Electron Microscopy Tomography Images

open access: yesAdvanced Engineering Materials, EarlyView.
Low‐voltage FIB‐SEM tomography combined with a image preprocessing pipeline improves phase contrast and enables reliable machine‐learning segmentation of conductive networks in lithium‐ion battery electrodes. Structural descriptors are extracted from segmented images, done semimanually and automated, and compared.

From Shear to Sound: Mechanics–Acoustics Mapping of TPMS Lattices

open access: yesAdvanced Engineering Materials, EarlyView.
Triply periodic minimal surface (TPMS) lattices are mapped across mechanical and acoustic performance, revealing that descriptors validated in compression fail under shear. First‐time comparison with trusses included. A transition from porous to resonance‐driven absorption emerges at 25% density.

A Dislocation Perspective on Strength and Toughness in Ceramics

open access: yesAdvanced Engineering Materials, EarlyView.
Dislocations in ceramics enjoy a long but yet under‐appreciated history. The three research waves for dislocations in ceramics highlight the topic evolution over the last 90 years. This review focuses on the impact of dislocation on strength and toughness in ceramics.

Study on Meshing Mechanism of Teeth Back and Dynamic Contact- impact of Gear Pair

open access: yesJixie chuandong, 2016
The meshing impact of teeth back which may lead to the phenomenon of low- transmission efficiency,poor accuracy and the decreased stability is studied by considering the teeth backlash,errors and deformation of the gears.

Realization of interdigitated back contact silicon solar cells by using dopant-free heterocontacts for both polarities

open access: yes, 2018
For crystalline-silicon (c-Si) solar cells, the interdigitated back contact (IBC) structure has been long known as an efficient way to approach the theoretical limit of efficiency.
