Breakthrough Photo-Rechargeable Supercapacitors Unveiled by IISc Researchers

Researchers from IISc have developed a novel supercapacitor that can be charged using light. It uses Zinc Oxide nanorods and Fluorine-doped Tin Oxide for enhanced performance. The discovery showcases unusual capacitance behaviors, paving the way for fast-charging, energy-dense applications like streetlights and wearable electronics.

In a groundbreaking development, researchers at the Indian Institute of Science (IISc) have designed a supercapacitor that can be charged by shining light on it. This innovation could revolutionize the way we use electronic devices.

The new photo-rechargeable supercapacitor, developed in collaboration with other experts, utilizes Zinc Oxide (ZnO) nanorods on Fluorine-doped Tin Oxide (FTO) to achieve superior performance. These materials are semiconductors with aligned energy levels, enabling higher energy storage compared to traditional capacitors.

Unexpectedly, the supercapacitor displayed increased capacitance under UV light, contrary to typical behavior. This promising technology holds potential for applications in streetlights, sensors, and microelectronic chips, according to the IISc team. Researchers aim to further optimize the design for improved performance with visible and infrared light.
