摘要:
Photovoltaic modules comprising back-contact solar cells manufactured using monolithic module assembly techniques comprising a flexible circuit comprising a back sheet and a patterned metallization. The module may comprise busses in electrical contact with the patterned metallization to extract the current. The module may alternatively comprise multilevel metallizations. Interlayer dielectric comprising islands or dots relieves stresses due to thermal mismatch. The use of multiple cord plates enables flexible circuit layouts, thus optimizing the module. The modules preferably comprise a thermoplastic encapsulant and/or hybrid adhesive/solder materials. An ultrathin moisture barrier enables roll-to-roll processing.

摘要:
Methods and systems for interconnecting back contact solar cells. The solar cells preferably have reduced area busbars, or are entirely busbarless, and current is extracted from a variety of points on the interior of the cell surface. The interconnects preferably relieve stresses due to solder reflow and other thermal effects. The interconnects may be stamped and include external or internal structures which are bonded to the solder pads on the solar cell. These structures are designed to minimize thermal stresses between the interconnect and the solar cell. The interconnect may alternatively comprise porous metals such as wire mesh, wire cloth, or expanded metal, or corrugated or fingered strips. The interconnects are preferably electrically isolated from the solar cell by an insulator which is deposited on the cell, placed on the cell as a discrete layer, or laminated directly to desired areas of the interconnect.

A patient transfer device is utilized to transport infant patients between locations within a hospital environment. The patient transfer device includes a center, support section and a pair of side sections that can be moved into contact with each other to surround the infant patient. The first and second side sections each include a handle that can be brought into close proximity to each other and can be grasped by a single hand of a clinician. The patient transfer device includes a stiffening device that is positioned within the center section to provide support for the infant patient during transport. A hold down device is included on one or both of the first and second side sections to securely hold tubes and wires connected to the infant patient during transport of the infant patient.
摘要:
Semiconductor structures are produced by providing a 3C—SiC semiconductor layer containing a monocrystalline 3C—SiC layer by implantation of carbon in silicon on a first silicon substrate and applying an epitaxial layer of nitride compound semiconductor suitable for the generation of optoelectronic components onto the 3C—SiC semiconductor layer structure, wherein the epitaxial layer of nitride semiconductor is transferred onto a second substrate by bonding the nitride layer onto the second substrate surface and mechanically or chemically removing silicon and layers containing SiC, the second substrate being a metal with a reflectivity ≧80% or being substantially transparent.
