Scientists have developed a photovoltaic “solar paint” that turns almost any surface into a functional electricity generator.
Researchers at the University of New South Wales in collaboration with BASF created a quantum-dot-based coating using zinc oxide and titanium dioxide nanoparticles suspended in acrylic paint.
When applied in a 200-micrometer-thick layer, the material can generate approximately 110 watts per square meter under direct sunlight, achieving up to 17.2% energy conversion efficiency, with improved performance under diffused light conditions.
Key technical features include:
Works on concrete, metal, glass, wood, and plastics
Weather durability exceeding 15 years
Can be applied with standard rollers or spray systems
Captures a broader light spectrum than traditional silicon panels
At scale, the implications are massive. In Australia alone, around 800 million m² of building surfaces could theoretically generate up to 88 gigawatts of electricity, comparable to the country’s entire current power generation capacity.
