摘要:
For solar cell fabrication, the addition of precursors to printable media to assist etching through silicon nitride or silicon oxide layer thus affording contact with the substance underneath the nitride or oxide layer. The etching mechanism may be by molten ceramics formed in situ, fluoride-based etching, as well as a combination of the two.
摘要:
The instant article of manufacture is made by applying optical energy to one or more layers of nanoparticulate materials under predetermined conditions to produce a nanostructure. The nanostructure has layers of optically fused nanoparticles including a predetermined pore density, a predetermined pore size, or both. The predetermined conditions for applying the optical energy may include a predetermined voltage, a predetermined duration, a predetermined power density, or combinations thereof.

Described herein is a novel material that easily penetrates silicon nitride-based anti-reflective coatings, forming a high quality electrical contact. A method for metallization on a solar cell includes depositing a passivation layer on a silicon substrate of a solar cell, depositing derivatized metal particles onto the passive layer, heating the substrate of the solar cell to migrate surface coatings from the derivatized metal particles onto the passivation layer creating a diffusion Channel through passivation layer to the silicon substrate, and as the metal particles melt due to the heating on the substrate, the melted metal diffuses through the diffusion channel forming a metallic content with the silicon substrate.

摘要:
A molecule is wired into an electronic circuit by attaching a metal nanoparticle to the molecule and then electrically connecting a metal nanoparticle to the electric circuit. The metal nanoparticle interconnects can bridge the gap between small molecules and conventional electric circuits. An optical second harmonic also may be generated by impinging optical radiation having a first frequency on an array of molecularly bridged metal nanoparticles, to generate optical energy at a second frequency that is twice the first frequency. Red to blue light conversion thereby may be provided.

摘要:
A method for preparing resin chips for use as an intermediate product in the manufacture of artificial-granite and artificial-stone articles. The process consists of mixing a thermoplastic polyester-resin material with an alumina tri-hydrate (ATH) filler and with a pigment, if desired, in a heated extruder to produce a continuous stream of thermoplastic agglomerate. This product is allowed to cool, then it is cut, ground and screened to a predetermined size, as required to meet the size characteristics of the desired resin-chip product. The undersize fines produced by the grinding operation are recycled as thermoplastic feedstock to the extruder. The resin-chip material so produced may be further mixed with a filler, as required for a particular application, and packaged for sale to commercial users.
