Solar paint is an innovation that promises to transform any surface into a source of clean energy. There are several forms of this technology, including hydrogen, Quantum Dot cell and Perovskite, each with its own characteristics and benefits.
Solar energy has been a source of renewable energy rapidly growing, especially in the United States, where the annual growth rate is 42%. Now, a new innovation promises to further revolutionize the sector: solar paint. This technology promises to transform any surface into a source of clean energy, saving electricity and contributing to a more sustainable future.
Imagine applying a special paint to your home's roof, walls or even existing photovoltaic panels to generate extra electricity. This is the promise of solar paints, which go beyond conventional methods of capturing solar energy.
Discover the solar paints being developed by scientists around the world
Hydrogen solar paint
No Royal Melbourne Institute of Technology, in Australia, scientists have developed an innovative solar paint that depends not only on sunlight, but also on the humidity present in the air.
- Energy consumption in Brazil breaks historical records: 102.810 MW in 2025 and the importance of renewable sources such as solar, hydroelectric and wind power
- China and Saudi Arabia turn desert into energy powerhouse with world's largest battery storage system
- Nuclear fusion has found the miracle it needed on the road to commercial power plants
- Solfácil dominates the solar energy market in Brazil with R$4 billion in financing
How it works? By collecting water vapor, this paint generates electricity.
It contains a mixture of compounds that act as semiconductors, catalyzing the division of water atoms into hydrogen and oxygen.
Titanium oxide and synthetic molybdenum sulfide are the main components of this revolutionary solar paint.
Quantum Dot (CQD) Solar Cells
Researchers from University of Toronto created CQD ink to increase the efficiency of solar cells by up to 11%.
This technology uses nanoscale semiconductors incorporated into a photon-absorbing film.
The nanoparticles present in the paint allow greater absorption of light, including in the near infrared spectrum.
Imagine spraying these cells onto flexible surfaces or printing sun-sensitive dots onto flexible films.
Garden furniture, airplane wings and even the roof of a car could become energy generators.
Perovskite Solar Paint
Named after Russian mineralogist Lev Perovski, perovskite is a semiconductor material that converts solar energy into electricity.
In 2009, Japanese scientists Pioneers used perovskites in solar applications.
More recently, researchers from University of Sheffield created perovskite-based solar molecules by applying them via a spray painting method.
These photovoltaic cells, also called spray solar cells, have high light absorption capacity.
Imagine painting any exposed surface with this paint and harnessing the power of the sun.
Despite being revolutionary, there are still many challenges
Although solar paints promise a revolution in the energy sector, they face significant challenges such as low energy conversion efficiency.
Currently, these paints can only capture around 3 to 8% of incident energy, compared to traditional photovoltaic panels.
However, researchers are dedicated to overcoming these obstacles, aiming to make paint a viable and affordable option for generating clean energy.
As we move towards a more sustainable future, solar paint has the potential to become an essential tool in the transition to renewable energy sources.
Although still in the early stages of development, these innovative technologies represent a significant step towards a cleaner, more energy self-sufficient world.
