Buildings | Free Full-Text | Push-Out Analysis on the Shear Performance of a New Type of Bellow …
In this study, a new type of bellow-sleeved stud (BSS) was developed to mitigate the weakening effects of rectangular group stud holes on the slab. A steel corrugated sleeve with a diameter of 60 mm was employed to cover the stud, which served as an internal formwork to prevent the concrete from bonding with the root of the stud.
Interface Engineering for Fabricating Semitransparent and Flexible Window-Film-Type Organic Solar Cells | ACS Applied Materials & Interfaces
We fabricated window-film-type organic photovoltaics with flexible transparent electrodes (FTEs). By overcoming the poor adhesion between layers, we created ultrathin metal electrodes (bottom FTE) on flexible substrates and transferred conducting polymers onto the photoactive layer (top FTE), providing power conversion …
Sunfolding''s Unique Solar Bellows Selected for CA Project
The ancient air bellows has been repurposed once again, to drive solar tracker arrays created by Sunfolding, of San Francisco, in a 39 megawatt installation at an undisclosed California location ...
Passivated rear contacts for high-efficiency n-type Si solar cells providing high interface passivation quality and excellent …
In this work passivated rear contacts are used to replace point contact passivation schemes for high-efficiency n-type crystalline silicon solar cells.Our structure is based on an ultra-thin tunnel oxide (SiO 2) and a phosphorus-doped silicon layer, which significantly reduce the surface recombination at the metal–semiconductor interface.

In this study, a Janus BiTeCl/SnSe2 van der Waals (vdW) heterostructure is constructed and systematically investigated for its potential in solar cell applications using first-principles …
Multifunctional Modification of the Buried Interface in Mixed Tin‐Lead Perovskite Solar …
Mixed tin-lead perovskite solar cells can reach bandgaps as low as 1.2 eV, offering high theoretical efficiency and serving as base materials for all-perovskite tandem solar cells. However, instability and high defect densities at the interfaces, particularly the buried surface, have limited performance improvements.
Solar Panel Wiring Basics: Complete Guide & Tips to Wire a PV …
You should know that there are limitations for series solar panel wiring. In the U.S., solar strings are required to feature a maximum voltage of 600V, so solar arrays comply with article 690 section 7 of the National Electrical Code (NEC 690.7).
