Researchers at North Dakota State University (NDSU) have developed a new process for depositing anti-reflective conformal coatings that is compatible with roll-to-roll manufacturing processes, utilizes off-the-shelf equipment, and significantly reduces the use of hazardous materials. It is estimated to reduce operating costs by 50% and capital equipment costs by 33% to 50%.

Anti-reflective Coatings on Solar Cells and Windows

• Estimated 50% reduction in operating costs, and a 33% to 50% reduction in capital costs. • Compatible with standard roll-to-roll manufacturing processes and equipment. • Eliminates ammonia, silane, methane and other toxic or dangerous chemicals. • Small manufacturing footprint. • Refractive Index of over 2.1 achieved in testing, additional optimization in process.
