Smart coating predictions for solar PV

March 11, 2011 - Marketwire -- NanoMarkets issued a report on smart coatings' applications on solar panels to increase efficiency, lower costs and create higher value-added products. NanoMarkets believes that sales of smart coatings to the photovoltaic (PV) sector, which are negligible now, will reach $504 million in 2016, growing to $847 million in 2018.

Self-cleaning coatings deposited on PV panels promise higher panel performance and lower maintenance costs. Self-cleaning glass is already available from major glass manufacturers, so no great leaps in technology are required to deploy it widely in the PV space. By 2016, self-cleaning smart coatings sold into the PV sector will reach more than $150 million in revenues.

Electrochromic and similar on-demand tinting smart coatings will generate $222 million from sales to the PV sector in 2016. NanoMarkets believes that by then lucrative opportunities will have arrived in this sector through the melding of building integrated photovoltaics (BIPV) glass panels with electrochromic smart windows. NanoMarkets also foresees electrochromic PV windows that incorporate OLED technology, so that they can serve as lights after dark.

Thermochromic smart coatings are also expected to play a role in PV. These can be used to turn panels "off" under extreme heat conditions that could permanently damage them. Some PV technologies -- notably thin-film cadmium telluride (CdTe) PV -- are sensitive to heat; permanent degradation is possible if the panels are operated at too high a temperature.

Companies mentioned in this report:

Bayer MaterialScience, Cardinal Glass, Corning, Gentex, GlasNovations, Nippon Sheet Glass, Nissan, PPG, Peer, SAGE Electrochromics, Saint-Gobain, and Soldadigm.

Additional details about the report, "Smart Coatings in Photovoltaics," are available at It examines the role of self-cleaning, self-healing, electrochromic and thermochromic coatings in the photovoltaics space over the next eight years. It includes an assessment of where the main opportunities will appear and when and includes a detailed eight-year forecast of smart coating usage in the PV space, broken out by volume and value.
