Scientists have developed a pioneering new solar cell technology capable of harvesting energy from indoor light, potentially paving the way for battery-free household gadgets and devices. This advancement, utilizing perovskite materials, offers a sustainable and cost-effective alternative to traditional batteries, especially as the Internet of Things (IoT) continues to expand.

These new perovskite cells are six times more efficient than traditional silicon-based solar cells in absorbing low-power, ambient light found indoors. Researchers have overcome stability and longevity challenges associated with perovskite by using a combination of chemicals to reduce crystal defects. These improvements allow the solar cells to retain 92% of their performance after 100 days, compared to 76% for unaltered control devices.

These tiny solar cells, which can convert up to 37.6% of indoor light into electricity, hold the potential to eliminate the need for battery replacements in billions of small devices, representing a significant step towards a more sustainable future for consumer electronics.
