DuPont™ Solamet®

Superior solar cell efficiency

DuPont’s Solamet® has done more to
increase solar cell efficiencies and power output
than any other provider worldwide, no one else even comes close.

Efficiency Matters

higher cell efficiencies

A Brighter Future

Solamet® metallization pastes transformed over 400,000 homes in an isolated area of India. 300 million villagers previously lacked safe, clean, dependable electricity, but our solar solutions provided energy that’s safer, more reliable, more efficient, and cost effective.


Efficiency for widespread accessibility

The advancements in Solamet® have helped to increase the power output of solar panels by 30%. This means more reliable power with fewer panels and materials and less space. More power with fewer resources means lower overall cost and faster adoption of solar energy worldwide.

Even small efficiency gains can lead to lower overall costs of a PV system over time. Every 1% improvement in sunlight conversion efficiency could result in a 5% reduction in the cost of the overall solar power generation system.

Versatility for very specific needs

We’ve been on the cutting edge of solar cell efficiency for a long time. We were the first to offer:

·         Co-fire metallizations

·         Frontside chemistry

·         Enable LDE technology

Our solar solutions are simple, cost-effective, and offer higher cell efficiency (double-digit) and greater power output at any scale.

Solamet® photovoltaic metallization pastes have enabled sustainable development of China’s solar energy industry and have brought reliable electricity to rural areas.

Endurance for long-term reliability

With Solamet® metallization pastes, your solar cells will generate more reliable, efficient, safe, and robust power for 25+ years.
