Solar Energy Enhancement Protection Coating, Sealant and Adhesive

Thermal Interface for Solar Cells, Modules and Concentrator Photovoltaic Solar (CPV):

Concentrated Photovoltatic Solar (CPV) is 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 being used and convert it into electrical energy. Only when the junction temperature of the solar cells receiving the concentrated solar height is lowered to close to ambient temperature will the efficiency of the solar cells be maintained. Thermal dissipation is one of the key ingredients to enable such a solution.

AIT SOLAR Solutions include some of the most proven solutions in large area thermal management:

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

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

SOLAR-THRU SC7130 is designed to protect solar cells before lamination with other UV transparent encapsulant like EVA that may be corrosive for metalization on the solar cell and its interconnections when moisture and water penetrated through them. Having a thin coating of SC7130 before lamination of EVA encapsulant will extends the life of solar cell and protect the solar cells in high temperature, humidity and salt fog exposure.

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

Having a thin coating of SC7130 before lamination of EVA encapsulant will extends the life of solar cell and protect the solar cells in high temperature, humidity and salt fog exposure. For solar panels that are not protected and in direct contact with EVA encapsulant, CC7133 can be applied to the edges of the solar panels and structural supports for protecting against salt fog penetration and corrosion.

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 cases, inorganic salt, that phase-changes to liquid at a high enough temperature to store the energy.

SC7090-UVB have been proven to provide unparalleled protection for outdoor LED display against yellowing and extend the brilliance of the outdoor display. SC7090-UVB is among few coating that are transparent and non-yellowing coating that protects electronics and metal surface against acid rain and other corrosive elements. It is one of the few such coatings that can be applied with dipping, brushing and spray coating.

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

SOLAR-THRU™ SC7150 has the UV stability of PVDF and is engineered as an ambient temperature curing coating that can be either pre-applied or used for 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.
