THIN FILM PHOTOVOLTAICS: THE NEXT EVOLUTION OF SOLAR TECHNOLOGY
Sharp’s thin film product pairs amorphous silicon with a layer of microcrystalline silicon to achieve high stability and performance. Produced with less than one percent of the silicon used in crystalline solar cells, thin film products offer high performance with less semiconductor material. With a low temperature coefficient for output power, thin film generates greater energy than its crystalline silicon counterpart in geographic regions where temperatures are high. In warm climates, this translates into more kilowatthours per kilowatt. Certified to IEC 61646, these modules are not UL-listed and are exclusively for behind-the-fence applications.

Advantages of PPC's Ion-Beam-Sputtered (IBS) Dielectric Thin Films
--------------------------------------------------------------------------------
Durable, dielectric thin films are easy to clean and chemically resistant
Dense, non-porous structure is insensitive to moisture
Low scatter and absorption losses result in high-damage thresholds
Repeatable, highly controlled process for precise layer control
--------------------------------------------------------------------------------
At PPC, we use ion-beam sputtering (IBS) technology because IBS is a repeatable and controllable process that results in dense, durable, high-damage-threshold thin films. Since the materials are directly sputtered onto the substrate, the process can be precisely controlled and easily automated so that films can be deposited with extremely high accuracy and repeatability.
Unlike conventional evaporative and ion-assisted films that have porous microstructures, IBS films have extremely densely packed structures that make them impervious to water vapor, resulting in an insensitivity to changes in heat and humidity, even in a vacuum environment.
Types of coatings that PPC does every day on standard or customer-supplied substrates:
High reflectors
Anti-reflection (ARs)
Beamsplitters
Polarizers
Partial reflectors
Dichroic mirrors
Non-polarizers
Low dispersion
Broadband dielectric

OptoSigma supplies a wide selection of optical thin film coatings. These coatings are often provided as part of the optical component but they may also be ordered separately to be applied to an uncoated element. For example, it is possible to apply an Anti-Reflection coating to any uncoated lenses, windows or optical fibers. Also reflecting coatings may be applied to uncoated substrates to form mirrors or partial reflectors. To make this process simple we have listed some of our most common standard coatings. To order you simply append the coating suffix to the base part number and specify the surfaces to be coated. If you don't find the exact coating you need please ask us to provide you with a custom solution. Our coating engineers will use the latest design software and production techniques to provide you with the coating you require.

Thin film coating is a vacuum deposition procedure used to enhance the transmissive properties of an optical surface. The most common types of dielectric coatings are anti-reflection and high reflection coatings, but beam-splitter, band pass filter, edge filter, and polarizing coatings are also available. Because thin film coatings are more durable than optical glass, coatings also help protect an optic surface from scratches and the environment.
Optimax produces optics up to 300mm in diameter with a wide variety of narrow and broadband anti-reflection coatings including doublet interface coatings. Both metal and dielectric mirror coatings are also available. For custom coatings, we utilize TFCalc thin film design software. Please see the reverse side for sample reflectance curves.
Optimax performs test runs of all coatings before beginning production to ensure a good design. We use a Perkin-Elmer Lambda 900 Spectrophotometer to check the performance of the coating upon completion. Adhesion, abrasion, and humidity tests are available to verify coating durability in accordance with sections of MIL-C-675C, MIL-C-48497A, and MIL-C-13508C specifications. Laser damage testing is also available upon customer request.

he offered HALIDES are useful as starting materials for production by thermal evaporation of transparent thin-film interference coatings, which improve the optical characteristics of workpieces made of glass, quartz, single crystals, semiconductors, etc.
Used for deposition of mono- and multilayer optical coatings, they are effective in ultraviolet, visible and infrared spectral regions. Halides, fluorides in particular, is the most early class of film-forming materials, used as one of the first as thin-film dielectric antireflecting coatings in optics.

Nor-Cal offers an extensive selection of commonly used quartz crystal feedthroughs, sensors and multi-channel monitors, cables, quartz crystals, accessories and replacement parts for use in semiconductor, optical and industrial thermal deposition processes. Custom feedthroughs are available with a variety of flanges in all sizes.
Our coating instrumentation products support one of the more popular methods of thin film measurement and rate control _ the crystal monitor, which utilizes the piezoelectric properties of a quartz crystal.
The electrical characteristics of the crystal, which is held in place by the sensor, change during deposition. Single sensors are generally used for short deposition runs, whereas, dual sensors allow for longer runs. Dual sensors require an airline to operate a pneumatic shutter which covers one crystal at a time. The sensor is either welded to the feedthrough or attached with connectors. Most sensors are available with cooling lines.
The application determines the correct choice of sensor. The sensor determines compatible feedthroughs and cabling. The chamber determines the appropriate feedthrough and flange. For application temps up to 150°C, electrical connection between the sensor and feedthrough is accomplished with a vacuum coaxial cable. A bakeable, one piece sensor/feedthrough replaces the standard in-vac cable with a stainless steel high-temp coaxial line for high temperature applications up to 300°C.

Thin Film Polarizers (TFPs) can split a laser beam into two parts with orthogonal polarizations. Conversely, TFPs can be used to combine two beams with orthogonal polarizations. TFPs consist of a coated plate, which is oriented at Brewster’s angle with respect to the incoming beam. The thin-film coating serves to enhance the beam’s s-polarized reflectivity, while maintaining the p-polarized component’s high transmission.
