Efficient tandem solar cells with solution-processed perovskite on textured crystalline silicon

Science, 2020
Growing perovskite on textured silicon Wide–band gap perovskites could boost the efficiency of silicon solar cells by forming tandem cells, but usually the perovskite must be grown on a smoothed side of the silicon cell because the material grown on the ...

Silicon nitride passive and active photonic integrated circuits: trends and prospects

Photonics Research, 2022
The use of silicon nitride in integrated photonics has rapidly progressed in recent decades. Ultra-low-loss waveguides based on silicon nitride are a favorable platform for the research of nonlinear and microwave photonics and their application to a wide

SILICON

Annual Review of Plant Physiology and Plant Molecular Biology, 1999
▪ Abstract  Silicon is present in plants in amounts equivalent to those of such macronutrient elements as calcium, magnesium, and phosphorus, and in grasses often at higher levels than any other inorganic constituent. Yet except for certain algae, including prominently the diatoms, and the Equisetaceae (horsetails or scouring rushes), it is not ...

Silicone emulsions

Advances in Colloid and Interface Science, 2006
Silicone polymers are a class of hybrid organic/inorganic polymers, that show desirable surface properties such as low surface energy and high flexibility, which enables even a very high molecular weight chain to achieve optimal orientation at the interface.

Pathways toward commercial perovskite/silicon tandem photovoltaics

Science
Perovskite/silicon tandem solar cells offer a promising route to increase the power conversion efficiency of crystalline silicon (c-Si) solar cells beyond the theoretical single-junction limitations at an affordable cost. In the past decade, progress has

SILICON NANOCRYSTALS ENABLING SILICON PHOTONICS

2010
Silicon Photonics is an emerging field of research and technology, where nano-silicon can play a fundamental role. In this chapter, the main building blocks of Silicon Photonics ( waveguides, modulators, sources and detectors) are reviewed and compared to their counterparts made by Si nanocrystals.

Silicon/silicon oxide and silicon/silicon nitride multilayers for extreme ultraviolet

Optical Engineering, 1991
Si/SiO2 and Si/Si3N4 multilayers have been fabricated using a locally made reactive diode ri-sputtering system. The layer alternation is obtained by modulating a partial pressure of oxygen or nitrogen near the sample using a silicon target with argon as sputtering gas.

Gluing silicon with silicone

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1998
Abstract Problems and solutions concerning the gluing of silicon detectors are discussed. The R & D work for the HERA- B vertex detector system led to gluing studies with epoxy and silicone-based adhesives used on ceramics and carbon fibre. The HERA- B solution using a silicone glue is presented.

Silicon-silicon interfaces

Applied Physics Letters, 1982
A wide variety of measurements on silicon grain boundaries shows that the electronic properties of such boundaries are much like those of Si surfaces in all essential respects. Moreover, the properties of ’’clean’’ surfaces and lightly contaminated surfaces can be studied on many crystallographic orientations of the interfaces without the need for ...

Silicon and Silicone Levels in Patients with Silicone Implants

1996
Although a potential link between silicone gel breast implants and autoimmune connective tissue disease has been suggested, none has been proven. The potential role of silicone as an immune adjuvant remains very controversial. Currently available techniques do not easily allow precise measurements of silicone in tissues.
