Sunlight-Powered Self-Charging Energy Storage Device

Recently, scientists at the Centre for Nano and Soft Matter Sciences (CeNS), Bengaluru, under DST, developed a photo-rechargeable supercapacitor that can both capture and store solar energy.

  • It reduces cost, complexity and energy loss by integrating solar harvesting and storage in a single device, aiding clean and decentralised energy solutions.

What Has Been Developed?

  • A photo-capacitor (sunlight-powered supercapacitor) that converts sunlight into electricity and stores it simultaneously.
  • Unlike conventional systems (solar panel + battery/supercapacitor), this device works as a single integrated unit, eliminating extra power management electronics.

How Does It Work?

  • The device uses nickel-cobalt oxide (NiCo₂O₄) nanowires grown directly on nickel ....
