Scientists have set a new record for generating energy from indoor light using a new generation of perovskite solar cells.

The team, led by scientists at University College London (UCL), said the achievement could lead to a battery-free future where remote controls and headphones could be powered by ambient artificial light.

Perovskite is touted as a potential breakthrough in renewable energy due to its remarkable properties. These properties help it convert light into electricity more efficiently than traditional silicon solar cells.

Perovskite solar cells are less expensive and can be easily manufactured. However, high-density traps can disrupt the flow of charge and energy can be lost as heat.

UCL researchers reduced the density of these traps by introducing the chemical rubidium chloride and generated record energy from the light inside the room.
