Influence of Arc Faults on Pressure Production Characteristics in AC Turret of UHV Transformers

open access: yesHigh Voltage, EarlyView.
ABSTRACT The overpressure caused by arc fault in the oil tank can lead to a transformer explosion. Since the AC turret of transformers serves to connect the transformer windings with the AC busbar, the arc current can be extremely high if an earth fault arc occurs leading to potentially hazardous pressure.

On the Electron Transport in Simplified IBC‐SHJ Solar Cells With MoOx Blanket Layer

open access: yesProgress in Photovoltaics: Research and Applications, Volume 34, Issue 5, Page 523-532, May 2026.
In this work, we present a study of electron transport through a novel (n)nc‐Si:H/MoOx stack to improve the understanding and performance of simplified IBC‐SHJ solar cells with MoOx blanket layer. The champion solar cell fabricated with the optimized contact stack and metalized with copper electroplating enables efficiencies beyond 23.5%.

What Is a Polyolefin? A Critical Overview of Ethylene Copolymers Used as Solar Photovoltaic Module Encapsulants

open access: yesProgress in Photovoltaics: Research and Applications, Volume 34, Issue 4, Page 367-395, April 2026.
Polyolefin encapsulants are gaining dominance in PV modules, yet confusion persists around PO, POE, and TPO definitions. This study clarifies terminology, reviews materials, and properties and proposes a taxonomy to improve understanding, communication, and reliability in solar module manufacturing.

Fast and Simple Series Resistance Imaging for Tandem Solar Cells Using Differential Luminescence

open access: yesSolar RRL, Volume 10, Issue 6, 29 March 2026.
This article presents a method for imaging the series resistance of subcells in a multijunction device. It requires few input properties, no current or voltage calibration and only three measured images. Validated on single junction and multijunction perovskite‐based devices, this method provides a practical tool for advancing photovoltaic research and
