New material to improve efficiency of solar panels

Honeywell Electronic Materials has launched a new material that improves the efficiency and power output of photovoltaic (PV) panels.

Honeywell Electronic Materials has launched a new material that improves the efficiency and power output of photovoltaic (PV) panels. The new product, called Honeywell SOLARC, is a transparent coating material that improves the light transmittance through the glass that covers PV panels, thus increasing the PV module efficiency and power output. This coating also significantly reduces glare from the glass, allowing the PV panels to better blend with its surroundings.

 

"SOLARC has already demonstrated the highest efficiency of any anti-reflective coatings, or ARCs, commercially available today," said Dmitry Shashkov, marketing director for Honeywell Electronic Materials. "This is another example of Honeywell applying its materials expertise, developed from 50 years of innovation for the semiconductor industry, to meet the challenges of the PV industry."

 

Most commercially available PV panels today lose approximately 4 percent of their potential power output due to light reflection from the front surface of the cover glass. In addition to the decreased electricity generation, the glare from the reflection light is considered aesthetically undesirable, especially in residential rooftop installations.

 

The new coating reduces reflection significantly, resulting in more light reaching the solar cell, which translates into higher electricity output. While use of such anti-reflective coating is relatively low in the PV industry today, it is widely expected to become the industry norm over the next few years, according to the major PV manufacturers.
