Forming PV Frames
Nordson Corp. in Westlake, Ohio, has designed a system to improve the
production process and durability of photovoltaic (PV) module framing. The
system is made up of a bulk melter, gear metering head and dispense
applicator to streamline the glazing/framing process, deliver consistent
material application and improve module durability.
The purpose of sealants in framing/glazing PV modules
is both to bond the encapsulant sandwich to the frame and help seal the
module from the elements. A dispensing system uses gear metering
technology for consistent precise metering of material. Gear metering
precision, along with clean cutoff by the applicator, allows optimization
of sealant material. Consistent application of material improves
durability of the finished goods by guarding against low spots or voids
where moisture could migrate into the module and render it useless.
Similarly, use of too much adhesive is both costly and squeeze-out of
excess material can result in quality problems. www.nordson.com/solarsolutions
Utility Promotes Photovoltaics
A new brochure from Super Sky in Mequon, Wis., discusses how the
company’s products can improve the energy efficiency of commercial
offices and industrial manufacturing sites. The North Light Energy Island
produces electricity and provides natural light. Vertical glazing on the
shade side of the system produces natural light. Diffused light from the
array enhances interior spaces. Photovoltaics can be used in covered
walkways, shading parking area, entrances and other applicable spots.
PV Takes on an Artful Approach at San Jose’s Library
With the opening of the Pearl Avenue Branch Library in San
Jose, Calif., the city has become the first municipality in the United
States to install permanent public art that combines photovoltaic (PV)
cells and art glass in an architectural application.
Artist Lynn Goodpasture’s public art piece entitled Solar Illumination
I: Evolution of Language, commissioned through the San Jose Public Art
Program, integrates green technology and art. The artist collaborated with
Peters Glass Studios in Portland, Ore., in the creation of an artwork that
incorporates glass-embedded PV cell technology that in turn powers a
suspended glass LED-illuminated lamp.
The artwork includes four art glass windows in the
building’s southwest corner that convert sunlight to 24-Vdc electricity. For
this project, art glass fabricator Peters Glass Studios translated the
artist’s design directly onto float glass by airbrushing a combination
of transparent, translucent and opaque vitreous enamels in multiple
layers. The PV glass was developed by laminating PV cells within two
layers of tempered float glass. The art glass and the laminated PV glass
were then combined into an insulating glass unit for installation on-site.
The artwork’s imagery explores the evolution of
alphabets as the foundation of the written word. Each window contains
characters in scripts that are the basis for written Latin, Russian,
Vietnamese and numerous Indian languages. “We are all one” is engraved
repeatedly on the lamp in cuneiform. Goodpasture explains that Solar
Illumination I: Evolution of Language links the past with the future by
exploring the first writings of humankind, at the same time the art
incorporates the newest applications of solar and LED technologies.
SCHOTT Solar Researchers
Nominated for Germany’s President’s
Dr. Nikolaus Benz and Dr. Thomas Kuckelkorn of SCHOTT Solar were among the
nominees for the German “Federal President’s Prize for Innovation and
Under the direction of Drs. Benz and Kuckelkorn, SCHOTT
Solar developed a concentrated solar power (CSP) receiver for solar power
plants with higher efficiency than previously available.
In SCHOTT Solar’s receiver technology, the solar
irradiation is trapped using large reflector surfaces, bundled and then
converted into usable energy.
