Coal-based graphitized activated carbon for solar energy powered supercapacitor IoT applications Energy Convers. Manag. (IF 9.9) Pub Date : 2024-08-24 Mousumi Bora, Debashis Sarmah, Santhi Maria Benoy, Abhishek Hazarika, Akhil Rajbongshi, Binoy K Saikia
Solar cells show promise as energy conversion gadgets, but their extended use is limited by intermittent sunlight. Self-powered solar cell integration with an electrical energy storage system could be one solution to this problem. Therefore, we have developed a coin cell supercapacitor (SC) device based on coal-based graphitized carbon materials and integrated with solar cells to assess its efficiency
