Thermal Interface for Concentrator Photovoltaic Solar (CPV):

Concentrated Photovoltatic Solar (CPV) gaining momentum and is targeted to achieve close 40% efficiency.

One of the key requirements to enable such focused energy conversion is to dissipate the excess energy that is not be converted into electrical energgy. Only when the junction temperature of the solar celss receiving the concentrated solar is lowered to close to ambient temperature will the efficiency of the solar cells be maintained. Thermal dissipation is one of key ingredient to enable such solultion.

AIT SOLAR Solutions include some of the most proven solution in large area thermal managements:

• Conformable Compressible Phase-Change CPR7153 and COOL-SILVER™ PAD have been proven in computer and microelectronic applications. It is not only stable against UV but also hydrophobic to resist moisture degradation.
• COOL-GEL CGL7013 and COOL-GREASE™ CGR7013 are also used extensive for high power dissipation and have the proven long-term reliability.

Moisture and Anti-Glare Coating for Concentrated Solar Power (CSP)

SOLAR-THRU™ SC7130 is an anti-glare PVDF coating that provides "total transparency" from UV to infrared. It is proven to have long-term stability under direct sun exposure and eliminate glare to allow more solar energy transmission onto solar cells to achieve the maximum conversion efficiency

Concentrated solar power, or CSP, works by using an array of paroabolic mirrors and/or lenses to focus a large area of sunlight (solar thermal energy) onto a small area. Most CSP systems work by heating up water and some in inorganic salt that phase-change to liquid at high enough temperature to store the energy.

Coated metal that can easily be formed into parabolic shpe is one of the most cost effective form of mirrors. Metals such as polished aluminum or coated silver or other metal requires passivation to maintain the long term ability to reflect the solar thermal energy. AIT Solar coating SOLAR-THRU™ SC7150 is one of the most effective PVDF coating for such application.

SOLAR-THRU™ SC7150 has the UV stability of PVDF and engineered as ambient temperature curing coating that can be either pre-applied or used as repair coating. The transmission coefficient is close to 96% at 2.5 mil or 65 micron thickness of coating from UV to infra-red frequency range.
