The technology behind solar panels is surprisingly basic, so you may be tempted to make your own from scratch. But should you?

If you stop to think about it, it’s a marvel that we can harness energy from the sun. But we do, thanks to solar panels equipped with photovoltaic cells that convert sunlight to electricity. That’s no ...

How much better, scientists thought, if we could make self-repairing and even self-assembling solar panels. By the mid-2030s, we could. Living solar panels, also known as biological photovoltaics ...

Photovoltaic efficiency has come a long way over the decades, but there’s always room for improvement. A new study analyses how to make solar thermoelectric generators, or STEGs, more efficient by ...
