研究目的
Investigating the use of solution-processed ultra-thin NiO and Ag nanoparticle film as an intermediate layer to enhance the charge recombination efficiency in PbS QD dual-junction tandem solar cells.
研究成果
The solution processed ultra-thin NiO/Ag NP layer is an efficient IML for charge recombination in QD PbS homo-tandem solar cells, significantly simplifying the manufacturing processes and permitting solution deposition for each layer. The tandem cells outperformed their corresponding subcells, demonstrating the advantage of using PbS QDs in tandem solar cells.
研究不足
The study focuses on the use of solution-processed NiO and Ag nanoparticle film as an intermediate layer, which may have limitations in terms of scalability and compatibility with other materials or processes.
