NAT is Key Contractor on Second Grant for Reactive Innovations

BOSTON, May 1, 2006—Neo-Advent Technologies, LLC is selected to be a key co-development sub-contractor on a grant awarded to Reactive Innovations, LLC (RIL) by the Department of Energy to develop a new barrier coating for advanced photovoltaic modules.

The Department of Energy is interested in improving renewable energy technologies such as photovoltaics to allow them to reach their full potential. A critical need for photovoltaic module packaging is the development of barrier coatings to protect solar cells from water and water vapor. Not only must these coatings be impermeable to water vapor, but they must also be optically transparent, stable at high temperatures, unaffected by UV radiation, chemically resistant, and easy to apply, giving a low cost. Furthermore, coating adhesion to commonly used polymeric encapsulants and backsheets, such as ethylene vinyl acetate (EVA) and polyvinylflouride (PVF), must be excellent. It is highly desirable to have one material and application technique that would work for all types of solar cells.

Neo-Advent Technologies (NAT) and its partners Reactive Innovations, LLC (RIL) and Madico are formulating, designing, and fabricating a photovoltaic device barrier coating (PDBC) for use in renewable energy applications. To accomplish this, the team is developing a new technology by synthesizing novel materials and using them in a unique configuration. This technology will enable a photovoltaic module barrier coating that can be applied without the use of physical/chemical vapor deposition (PVD/CVD) processes.

NAT is inventing the chemical formulations of the barrier coating; RIL is designing a system that exhibits exceptional barrier properties while maintaining flexibility and ease of application; Madico is assisting in evaluating the samples and scaling the technology for commercialization.

The outcome of this barrier coating process will provide the government and industry with a coating system that meets or exceeds the performance of presently used coatings and their corresponding pretreatments/primers. The present focus of this technology is toward PV devices/modules, although it has a broad scope of applications where outdoor weather protection and barrier coating protection are required. Some of the areas where this technology can be successfully adopted include aircraft, ships, electronics, aerospace, automotive, construction, and scratch resistant coatings. Specifically, these markets include food/beverage packaging and barrier technologies for organic light emitting devices.

Neo-Advent Technologies was founded in 2003 to develop cutting-edge technologies in pharmaceutical and material science.
