• Fabrication of Si NW-based solar cells and the hybrid nanostructure integrating with perovskite nanocrystals.
• Improvement of Si NW surface by formation controls, thermal annealing, and applying of nanocrystals.
内容
Vertical-oriented Si NW arrays with smooth, nanodot-, or NW-structured surfaces offer many desirable advantages for advanced device applications. They are of great interest for increasing light trapping as a black Si substrate to enhance solar cell performance. Energy transfers using nanocrystals (NCs) for hybrid nanostructures that combine absorbing components with Si NW-based solar cells also open new possibilities in light harvesting. In addition, applying H2 annealing or NC coating efficiently helps to minimize the interfacial defects on the top surfaces of Si NW solar cells.
まとめ
• NWs and hybrid nanostructures offer opportunities for leveraging their distinct properties and synergistically integrating them to generate novel functionalities.
• Through in-depth exploration and comprehension of the intricacies surrounding these structures, a wide range of exciting applications is expected to emerge across various fields, paving the path for innovative advancements in technology and scientific discovery.
