Accurate and reproducible color characterization is essential for colored building integrated photovoltaic products, both for manufacturing quality control and assessing long-term color stability. However, existing characterization techniques struggle to a ...

Ultraviolet-induced degradation (UV-ID) of various PV cell types was analyzed under optical UV filters with different cutoff wavelengths. Cell types studied included interdigitated back contact (IBC), passivated emitter and rear totally diffused (PERT), an ...

Soiling is the major cause of power loss of photovoltaics (PV) and concentrated solar power (CSP) in desert areas. Electrodynamic cleaning system (EDS) is an automatic and water-free integrated cleaning system for mirrors or solar panels, which uses pulsed ...

The mechanical failure of one cell is sufficient to lead to the end of service of a solid oxide fuel cell (SOFC) stack. Therefore, there is growing interest in gaining knowledge on the mechanical properties of the cell materials for stress analysis. This s ...

As the performances of Solid Oxide Fuel Cells (SOFC) get attractive, long term degradation becomes the main issue for this technology. Therefore it is essential to localise the origin of degradation and to understand its processes in order to find solutions and improve SOFC durability. The electrode microstructure ageing, in particular nickel grain coarsening at the anode side, is known to be a major process to cause performance loss. The increase in nickel particle size will diminish the Triple Phase Bound

The common technology for solid oxide fuel cells (SOFC) is based on a cermet (ceramic-metal composite) anode of nickel with yttria stabilized zirconia (YSZ), often used as the supporting structure. One of the main limitations of this technology is the tole ...

Bisphenol A polycarbonate (PC), a lightweight and impact-resistant glass substitute widely used in structural and optical applications, suffers from hydrolytic degradation under heat and humidity, limiting its long-term outdoor reliability. In this study, the hydrolysis of PC under neutral and acetic acid conditions was systematically investigated via accelerated aging at a controlled temperature, humidity, and acetic acid concentration. Mechanical degradation was assessed by tensile testing, whereas molecu

As the performances of Solid Oxide Fuel Cells (SOFC) get attractive, long term degradation becomes the main issue for this technology. Therefore it is essential to localise the origin of degradation and to understand its mechanisms in order to find solutions and to improve SOFC durability. Microstructural evolution of anode supported solid oxide fuel cells (SOFC) during medium-term stack testing has been characterized by scanning electron microscopy (SEM). A new technique is presented using low acceleration

In densely populated or mountainous countries where installation of large‐scale solar plants is challenging, photovoltaic (PV) modules in building applications offer a solution by transforming passive surfaces into energy‐generating systems. The need for f ...

The growing integration of photovoltaic (PV) systems into complex environments—such as rooftops, façades, and vehicles—has introduced new shading patterns and the need for accurate performance modeling under these partial shading conditions. In particular, building-integrated photovoltaics (BIPV) are often subject to thin shadows from nearby building components, vegetation, or infrastructure. These shadings can impact only portions of individual cells, leading to inhomogeneous irradiances that are difficult

Accurate clear-sky detection (CSD) is essential for reliable data analysis and performance assessments in photovoltaic (PV) systems. However, many advanced machine learning (ML) models function as “black boxes”, limiting their interpretability and trustworthiness. This study presents an interpretable Artificial Intelligence (AI) framework that combines high predictive performance with deep insight into model decision-making. Using a hand-labelled dataset from a fixed-tilt PV system in Golden, Colorado, USA,

The weakness of nickel-based solid oxide fuel cell anodes is their low ability to withstand re-oxidation at working temperature, especially for the anode-supported cell design. The volume expansion coming along with nickel (Ni) oxidation induces stresses i ...

Reliable and esthetically pleasing lightweight photovoltaic modules for building integration are expected to grow interest in the consumer market, especially for retrofitting older buildings and storehouses that are not structurally designed to withstand a ...

In situ forming implants are attractive for minimally invasive localized therapies such as aneurysm embolization. As for the superparamagnetic iron oxide nanoparticles (SPIONs), their deposition/injection in a target tissue area allows magnetically induced ...

Nickel oxide and yttria doped zirconia composite strength is crucial for anode-supported solid oxide fuel cells, especially during transient operation, but also for the initial stacking process, where cell curvature after sintering can cause problems. This ...

A solid oxide fuel (SOFC) cogenerates heat and electricity with high efficiency. Electricity is produced by the electrochemical reaction of a fuel (H2, CO, CH4) and an oxidant gas (O2, air). The SOFC standard design is based on an anode-supported electrolyte. The anode is composed of yttria-stabilized zirconia (YSZ) and nickel oxide (NiO). NiO is reduced in situ into metallic nickel during the first use of the fuel cell. Porosity is formed to compensate the volume shrinkage induced by the reduction (40 vol%

Performance degradation data obtained on single solid oxide fuel cells tested at 850°C with air and humidified H2 and using Ni-YSZ anode supported cells are presented. Microscopic investigation is carried out on both anode and cathode to quantify variation ...

Degradation observed on long term stack tests may be explained in part by microstructural changes of the electrodes. Particularly at the anode side, the coarsening of nickel particles will affect its performances. Increasing the metal particle size will first diminishes the Three-Phase Boundary (TPB) where fuel oxidation takes place, and secondly decrease the electronic conductivity [1]. In order to quantify the changes in anode microstructure, SEM images analysis is used. Some techniques can be time consum

As global decarbonization accelerates the need for extensive solar photovoltaic deployment, land‐use conflicts have become increasingly pressing. Integrating PV into the built environment emerges as an effective strategy to mitigate these challenges by generating electricity where it is consumed. However, the polymeric encapsulant—a core material in photovoltaic (PV) modules—introduces critical fire safety concerns, particularly in building applications with strict regulatory requirements. This review addre

Environmental transmission electron microscopy was used to characterize in situ the reduction and oxidation of nickel from a Ni/YSZ solid oxide fuel cell anode support between 300-500°C. The reduction is done under low hydrogen pressure. The reduction init ...
