Solar Paint

Detailed overview of innovation with sample startups and prominent university research

What it is

Solar paint is a conceptual technology that envisions paint containing tiny solar cells or light-absorbing materials that can convert sunlight into electricity. This would allow any surface coated with the paint to generate solar power.

Impact on climate action

Solar Paint in Distributed Solar PV advances climate action by transforming surfaces into solar panels. By harnessing sunlight to generate electricity, this innovation expands renewable energy access, reduces reliance on fossil fuels, and accelerates the transition to a low-carbon energy system, mitigating carbon emissions and combating climate change.
