‘British weather-proof’ solar panel that generates 20 per cent MORE energy in cloudy weather has been invented by scientists
- Improvement to the solar panel method makes it more sensitive to light
- Energy would be created in dimmer conditions such as in drizzle and cloud
- Layer thinner than a human hair produce around 20% more energy in low light
Scientists claim to have developed solar power technology that can produce around 20 per cent more energy in cloudy weather, compared to conventional solar cells.
Researchers say their co-called ‘British weather proof’ technology is cheaper, more energy efficient and more flexible than traditional solar panels.
It is also able to convert solar energy to electricity in low light conditions, when conventional technology is ineffective.

Scientists claim to have developed solar power technology that can produce around 20 per cent more energy in cloudy weather, compared to conventional solar cells. Researchers say their co-called ‘British weather proof’ technology is cheaper and more energy efficient
Australian researchers who created the technology believe their work represents a ‘significant step’ towards making the technology commercially viable.
Professor Lianzhou Wang, from the University of Queensland, said: ‘Essentially, we’ve developed solar technology that is British weather proof.
‘It can produce energy indoors or even when it is cloudy and wet.
‘It is also printable, flexible and transparent – meaning it could be used as a skin to power next generation electric cars or applied as a film to windows on buildings and homes.’
The technology uses tiny nanoparticles – called quantum dots – that are about five billionths of a metre in size and can be put into liquid form and printed.
These can be put onto surfaces and harden to form a flexible layer around seven times thinner than the width of a human hair at just ten microns.
When exposed to solar energy in a solar cell device, these quantum dots pass electrons between one another to generate electrical current.
While conventional solar cells can work under cloudy conditions, Professor Wang said quantum dot solar cells are better at producing energy because they absorb a broader spectrum of solar light compared to conventional solar cells.

He said this makes quantum dot solar cells around 20 per cent more efficient in low-light conditions than conventional solar cells.
Professor Wang also claimed to have achieved a 25 per cent improvement in solar cell efficiency over the previous world record.
He said: ‘This opens up a huge range of potential applications, including the possibility to use it as a transparent skin to power planes, homes and wearable technology.
‘This new generation of quantum dots is compatible with more affordable and large-scale printable technologies.’
