Abstract
In this study, Cu- and Zn-doped SnO2 nanoparticles (NPs) were synthesized by using the solvothermal method. The synthesized NPs were explored to check their supercapacitor, photovoltaic and magnetic properties. The Cu-doped SnO2 NPs showed a high specific capacitance of 386 F g−1 at 20 mV s−1 in 1 M KOH electrolyte and remarkable catalytic performance as a counter electrode (CE) for dye-sensitized solar cells (DSSCs), achieving a power conversion efficiency (PCE) of 10.70%, comparable to that of Pt CE. Moreover, Cu-doped SnO2 NPs displayed the highest room-temperature ferromagnetism, indicating their potential for magnetic device applications. Our results suggest that doped SnO2 NPs are promising candidates for multifunctional nanomaterials in energy and information technologies.
期刊介绍：
The Bulletin of Materials Science is a bi-monthly journal being published by the Indian Academy of Sciences in collaboration with the Materials Research Society of India and the Indian National Science Academy. The journal publishes original research articles, review articles and rapid communications in all areas of materials science. The journal also publishes from time to time important Conference Symposia/ Proceedings which are of interest to materials scientists. It has an International Advisory Editorial Board and an Editorial Committee. The Bulletin accords high importance to the quality of articles published and to keep at a minimum the processing time of papers submitted for publication.
