Does the light and shadow lamp generate electricity from solar energy

Can electricity be generated using Shadows?

NUS researchers have found a way to generate electricity from shadows. This common but often overlooked optical effect can now be harnessed to produce green energy under indoor lighting conditions, opening up new approaches in powering electronics.

Can solar cells produce energy under light?

In some solar cells, differences in the material properties can create energy under light. The team compared its generators to commercial solar cells that are typically used under full sunlight. With half of each device in shadow, the generators produced roughly twice as much power per surface area as the solar cells.

Could shadow-effect energy generators be used to produce electricity?

Shadow-effect energy generators, such as the one illustrated here, could someday be used to produce electricity. They create a current using the difference between bright spots and shady areas. The greater the contrast between light and dark, the more energy these generators can provide. Someday, shadows and light could team up to provide power.

How does a light & shade generator work?

They create a current using the difference between bright spots and shady areas. The greater the contrast between light and dark, the more energy these generators can provide. Someday, shadows and light could team up to provide power. A new device uses the contrast between bright spots and shade to create an electric current.

How do solar power generators work?

The greater the contrast between light and dark, the more energy the generator provides. So the team is working to boost the device’s performance by borrowing strategies from solar cells for gathering light. Increasing the light these generators absorb would allow them to better exploit shadows.

Could Shadows and light combine to power small electronics?

Someday, shadows and light could team up to provide power. A new device exploits the contrast between bright spots and shade to create a current that can power small electronics. “We can harvest energy anywhere on Earth, not just open spaces,” says Swee Ching Tan, a materials scientist at the National University of Singapore.
