Why in the News?
Indian scientists under the Department of Science and Technology (DST) have developed a photo rechargeable supercapacitor that can both capture and store solar energy in a single integrated unit, enabling low cost, self sustaining, and clean energy systems.
About the Device
- Known as a Photo Rechargeable Supercapacitor
- Integrates solar energy harvesting and energy storage
- Eliminates separate solar panels and batteries
- Reduces energy loss, cost, and system complexity
Developed By
- Researchers at the Centre for Nano and Soft Matter Sciences (CeNS), Bengaluru
- Developed under the Department of Science and Technology
Key Technology Used
- Binder free Nickel Cobalt Oxide (NiCoâ‚‚Oâ‚„) nanowires
- Uniformly grown on nickel foam
- Fabricated using in situ hydrothermal process
- Forms a porous, conductive three dimensional network
- Acts as both solar absorber and supercapacitor electrode
| [2014] With reference to technology for solar power production, consider the following statements:Â
1. ‘Photovoltaics’ is a technology that generates electricity by direct conversion of light into electricity, while ‘Solar Thermal’ is a technology that utilizes the Sun’s rays to generate heat which is further used in electricity generation process. 2. Photovoltaics generates Alternating Current (AC), while Solar Thermal generates Direct Current (DC). 3. India has manufacturing base for Solar Thermal technology, but not for photovoltaics. Which of the statements given above is/are correct? (a) 1 only (b) 2 and 3 only (c) 1, 2 and 3 only (d) None of the above |
