Detection Criterion for Progressive Faults in Photovoltaic Modules Based on Differential Voltage Measurements

open access: yesApplied Sciences, 2022
PV modules may experience degradation conditions that affect their power efficiency and affect the rest of the PV array. Based on the literature review, this paper links the parameter variation on a PV module with the six most common degradation faults ...

Effect of Photoconductive Properties of SiNx Passivation Film on Anti-PID Performance of Photovoltaic Cells and Modules

open access: yesMedžiagotyra, 2018
We investigated the impact of the photoconductive properties of crystalline silicon solar cells, having a SiNx passivation film, on potential induced degradation (PID) using voltage-corona (V-Q) and self-adjusting stead state (SASS) tests.

Review on the Sources of Power Loss in Monofacial and Bifacial Photovoltaic Technologies

open access: yesEnergies, 2021
An evaluation of the degradation effects on photovoltaic modules is essential to minimise uncertainties in the system operation. Bifacial photovoltaic technology is attracting attention due to the capacity of generating energy from the front and rear ...

Mechanistic Understanding of Polarization‐Type Potential‐Induced Degradation in Crystalline‐Silicon Photovoltaic Cell Modules

open access: yesAdvanced Energy & Sustainability Research, 2023
Potential‐induced degradation (PID) has been identified as a central reliability issue of photovoltaic (PV) cell modules. Several types of PID depend on the cell structure. Among those types, polarization‐type PID, which is characterized by reductions in

Phillygenin inhibits inflammation in chondrocytes via the Nrf2/NF-κB axis and ameliorates osteoarthritis in mice

open access: yesJournal of Orthopaedic Translation, 2023
Objective: Osteoarthritis (OA), widely seen in the elderly, is featured by cartilage degradation, subchondral bone remolding, and synovium inflammation. Currently, there is no cure for OA development.

Mitigating Potential-Induced Degradation (PID) Using SiO2 ARC Layer

open access: yesEnergies, 2020
Potential-induced degradation (PID) of photovoltaic (PV) cells is one of the most severe types of degradation, where the output power losses in solar cells may even exceed 30%.

Bone mesenchymal stem cell extracellular vesicles delivered miR let-7-5p alleviate endothelial glycocalyx degradation and leakage via targeting ABL2

open access: yesCell Communication and Signaling, 2023
Background Endothelial glycocalyx (EG) is an active player and treatment target in inflammatory-related vascular leakage. The bone marrow mesenchymal stem cells (bMSCs) are promising potential treatments for leakage; however, the therapeutic effect and ...

On Site Tests for the Detection of Potential Induced Degradation in Modules

open access: yes, 2013
This paper presents different test alternatives which can be used on-site in a PV installation to detect potential induced degradation (PID) in modules. The testing procedures proposed are: thermal imaging; electroluminescence imaging; open circuit voltage measurements; operating voltage measurements; IV curve measurements; and dark IV curve ...

IGF-1 and PDGF-bb suppress IL-1β-induced cartilage degradation through down-regulation of NF-κB signaling: involvement of Src/PI-3K/AKT pathway. [PDF]

open access: yes, 2011
Interleukin-1β (IL-1β) is a pro-inflammatory cytokine that plays a key role in the pathogenesis of osteoarthritis (OA). Growth factors (GFs) capable of antagonizing the catabolic actions of cytokines may have therapeutic potential in the treatment of OA.
