This is a stretchable solar cell. It can withstand stretching up to 30% when pulled from both ends. This could lead to robotic skin that are durable and can pick up sensory details from the environment.The device's electrode is made from a unique liquid metal called eutectic gallium-indium, which conforms to a surface as it lengthens and relaxes. "Eutectic" refers to a mix of elements or compound that remains liquid at lower temperature than either of its components does alone.
This is good as solar cells eliminate the need for a battery cell or charging. Also, its stretchability is good as it can withstand damage from wear and tear like scratching, grazing... this is not commercially available yet, but I think it will be very useful when it comes out. I think it can be used for:
- Robots in space
- Shopping centre walls
- Cars
