Recent studies showed that SHJ solar cells can be prone to PID when encapsulated with a low volume resistivity encapsulant, such as ethylene vinyl acetate (EVA). These studies also demonstrated that their degradation mechanism is different from Al-BSF modu ...
We investigate the phase behavior of surface-functionalized silica colloids at both the molecular and macroscopic levels. This investigation allows us to relate collective properties such as aggregation, gelation, and aging directly to molecular interfacia ...
Hybrid integration and especially the packaging of microelectromechanical systems (i.e. MEMS) cannot rely on standardised packaging solutions due to the diversity of microsystems. As an example, the packaging requirements of a pressure sensor are different ...

This paper reports on low-temperature and hermetic thin-film indium bonding for wafer-level encapsulation and packaging of delicate and temperature sensitive devices. This indium-bonding technology enables bonding of surface materials commonly used in MEMS ...
Silicon (Si) photonic micro-electro-mechanical systems (MEMS), with its low-power phase shifters and tunable couplers, is emerging as a promising technology for large-scale reconfigurable photonics with potential applications for example in photonic accele ...
In densely populated countries, little free land is available for the deployment of photovoltaics (PV) in field installations. In addition, 40% of the world's demand for electricity is related to buildings. These facts provide a strong argument for the acc ...
Micro solid oxide fuel cells (μ-SOFCs) based on MEMS fabrication processes have become an increasingly attractive option for portable power generation applications, due to their high power density and their compatibility with hydrocarbon fuels. For system ...
We propose a nonparametric method for constructing multivariate kernels tuned to the configuration of the sample, for density estimation in R-d, d moderate. The motivation behind the approach is to break down the construction of the kernel into two parts: ...
The quantity of MEMS manufacturers has considerably been increasing these last years. This doesn't mean that the introduction of such products on the market has become easier. A packaging operation is needed to obtain a usable product out of a microsystem. ...
Precise packaging of nanoliter amounts of liquid in a microsystem is important for many biomedical applications. However, existing liquid encapsulation technologies have limitations in terms of liquid waste, evaporation, trapped bubbles, and liquid degrada ...
