摘要:
The present invention discloses a fire resistant laminate and incorporating the laminate into an encapsulant for a photovoltaic module that may be used in a photovoltaic building material. More particularly, the present invention relates to fire resistant encapsulant that may be used in a triple junction amorphous silicon photovoltaic module that is fire resistant on a wide variety of buildings roofs, including residential housing, and that is flexible and lightweight. A fire resistant additive, such as solid glass spheres, may be added to encapsulant material to produce a fire resistant, cut resistant, lightweight photovoltaic device.

A method of heating in a vacuum atmosphere in the presence of a plasma, comprises the following steps: a) providing infrared radiation means (16) in a vacuum chamber (10); b) providing a first electrical conductor (18) to the infrared radiation means (16); c) providing a second electrical conductor (20) from the infrared radiation means (16); d) putting an electrical voltage over said infrared radiation means (16); e) preventing the first conductor (18) and the second conductor (20) from having an electrical voltage above +55 Volt. The advantage is that arcing is avoided.

Disclosed herein is an improved gas gate for interconnecting regions of differing gaseous composition and/or pressure, more particularly between atmosphere and a vacuum. The gas gate includes a cylinder within a housing situated between the regions of differing gaseous pressure, wherein the gas gate provides for choke mode transonic flow of air leaks between the regions. A web of substrate material is adapted to move between the regions with at least one roller in a first region and at least one roller in a second region. The rollers are positioned to create sufficient tension as the web advances over the top peripheral portion of the cylinder between the two regions or under the bottom peripheral portion of the cylinder between the two regions.

There is disclosed new and improved photovoltaic devices which provide increased short circuit currents and efficiencies over that previously obtainable from prior devices. The disclosed devices include incident radiation directing means for directing at least a portion of the incident light through the active region or regions thereof at angles sufficient to substantially confine the directed radiation in the devices. This allows substantially total utilization of photogenerated electron-hole pairs. Further, because the light is directed through the active region or regions at such angles, the active regions can be made thinner to also increase collection efficiencies.The incident radiation directors can be random surface or bulk reflectors to provide random scattering of the light, or periodic surface or bulk reflector to provide selective scattering of the light.While the present invention is applicable to photovoltaic devices formed from any type of semiconductor material, as for example, crystalline, polycrystalline, or amorphous semiconductor alloys or any combination thereof, disclosure herein is primarily directed to photovoltaic devices formed from amorphous silicon alloys preferably incorporating fluorine as a density of states reducing element. The disclosure is also directed to, without limitation, photovoltaic devices of the p-i-n configuration, both as single cells and multiple cells arranged in tandem.

A web support assembly for a moving web of substrate material includes a base having a primary support arm pivotally mounted thereto so as to be displaceable from a first position to a second position. The web support assembly includes a first biasing member in mechanical communication with the primary support arm. The first biasing member operates to impart a first biasing force to the primary support arm so as to move it from its first position to its second position. The system includes a dancer arm which is pivotally mounted to the primary support arm so as to be displaceable from a first position to a second position relative primary support arm. The web support assembly further includes a second biasing member in mechanical communication with the dancer arm. The second biasing member operates to impart a second biasing force to the dancer arm so as to move it from its first position to its second position. A roller is rotatably supported on the dancer arm. The roller is configured to engage a portion of the web. The web support assembly operates to maintain continuous contact between the roller and the moving web of substrate material as it passes through a multi-station processing system.

摘要:
A photovoltaic module which includes at least one photovoltaic cell which is encapsulated in a non-reacted, injection molded polymeric material, thereby forming an environmental seal around the cell. The photovoltaic cell(s) are incorporated into a photovoltaic panel having front and back sides and edges forming a perimeter, and also includes means for external electrical connection to the photovoltaic cell. The non-reacted injection molded polymeric material encapsulating the panel may form useful structures, such as shingles, blocks, cases, or boxes.
摘要:
A method for the low temperature, microwave enhanced, chemical vacuum deposition of thin film material onto a surface of a hollow member by creating a sub-atmospheric pressure condition adjacent the surface to be coated while maintaining the applicator through which microwave energy is introduced at substantially atmospheric pressure.
摘要:
A window assembly for transmitting relatively high power microwave energy from a waveguide, held at substantially atmospheric pressure levels, into a microwave reaction chamber at sub-atmospheric pressure levels. The window assembly provides for the transmission of microwave energy to generate a glow discharge plasma without suffering from catastrophic failure as a result of excessive temperature and pressure conditions.
