Indian Scientists Develop Revolutionary “All-in-One” Solar Device
Tech News, New Delhi / Bengaluru, February 3, 2026: In a major breakthrough for renewable energy, Indian scientists at the Centre for Nano and Soft Matter Sciences (CeNS), Bengaluru, have developed a single-unit device that can both capture and store solar energy at the same time.
Commonly, solar power systems require two separate parts: solar panels to collect sunlight and batteries to store the electricity. This new invention, called a “Photo-rechargeable Supercapacitor,” combines both functions into one compact device.
The device uses special “nanowires” (thinner than a human hair) that act as both a solar collector and a storage unit. This eliminates the need for bulky wires and separate battery packs. Under direct sunlight, the device is 54% more efficient at storing energy compared to standard storage methods. It is incredibly durable, maintaining its performance even after being charged and discharged 10,000 times. It doesn’t just need bright sun; it is sensitive enough to capture energy from dim indoor lighting as well.
How Will This Change the Future?
This innovation is a game-changer for the world of portable electronics. Because the device is so small and efficient, it could lead to:
-
Self-Charging Smartwatches: Fitness bands and watches that never need to be plugged in.
-
Lighter Gadgets: Smartphones and tablets that are thinner because they don’t need large, separate batteries.
-
Remote Power: Reliable energy for sensors and medical devices in rural areas where electricity is hard to find.
The research team, led by Dr. Kavita Pandey, believes this is a vital step toward making green energy more affordable and accessible for everyone.
