A new generation of flexible solar cells has been pioneered using a material known as perovskite.
The higher your vantage point, the more likely you’ll see more of the rainbow’s circle.

Each rainbow is personal – the rainbow you see isn’t exactly the same rainbow the next person sees. It’s all in the eye of the beholder.
Watching a solar eclipse is always fascinating. During the phase when the moon completely obstructs the sun, daylight gives way to a deep twilight sky.

Some parts of North America will witness a total solar eclipse in April 2024. This may seem far away, but you should think about preparing for this rare and fascinating phenomenon.
The sun’s rays often feel good on your skin, but can cause serious damage.

Our ancient ancestors didn’t have clothes or houses – but that constant exposure to the sun helped their skin protect itself from the worst sun damage.
Many places have banned sunscreens with certain chemicals in an attempt to help protect coral reefs.

Researchers have long suspected that an ingredient in sunscreen called oxybenzone was harming corals, but no one knew how. A new study shows how corals turn oxybenzone into a sunlight-activated toxin.

Plants need light to feed themselves, so they grow in ways that help them collect as much of it as they can. Sometimes that’s straight up, but not always.

The sky on other planets doesn’t look the same as the sky on Earth does. And that’s because of the different gases in Earth’s atmosphere.
Could solar power provide an alternative energy source for the web?

How much energy does the internet use, and - given recent technological advances - could it ever run on renewable energy alone?
Painting buildings white is a centuries-old method of staving off heat in countries like Greece.

A light invisible to humans makes chemicals in our skin very excited. In fact, the chemicals become so excited they change shape and become vitamin D.

Diatoms’ tricks may offer new insights that keep solar cell energy running efficiently and robustly throughout their processes.
Photosynthesis can teach scientists a lot about solar technologies.

Individual light-harvesting protein complexes have a remarkable ability. Light, which is normally effectively harvested, is also used to finely control how much of it should be harvested.
Kirkwall harbour, Orkney.

Orkney’s ultra-high incidence has been linked to the weak northern sun. So how come the more northern Shetlands are less afflicted?
Cheer up, it’ll be dark soon.

SAD has entered popular mythology, but that doesn’t make it real.
