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.

Underlying
Technology

  • Photovoltaic (PV) Cells or Light-Absorbing Materials: Solar paint would contain tiny PV cells or light-absorbing materials, such as organic semiconductors or quantum dots, that can convert sunlight into electricity.
  • Paint Formulation and Application: The solar cells or light-absorbing materials would need to be integrated into a paint formulation that can be easily applied to surfaces.
  • Durability and Weather Resistance: Solar paint would need to be durable and weather-resistant to withstand harsh environmental conditions.
  • Electrical Conductivity and Interconnections: The solar cells or light-absorbing materials in the paint would need to be interconnected to collect and transmit the generated electricity.
