研究目的
To boost the efficiency of dye-sensitized solar cells (DSSCs) by improving light harvesting through the introduction of plasmonic additives, specifically Au@Ag@SiO2 nanocuboids (GSS NCs), to achieve plasmon-enhanced DSSCs.
研究成果
The incorporation of broadband plasmonic Au@Ag@SiO2 nanocuboids (GSS NCs) into DSSCs significantly enhances light harvesting, leading to an average efficiency of 10.34% and a champion efficiency of 10.58%. The study demonstrates the potential of using plasmonic nanostructures with controllable optical properties to improve the performance of solar cells.
研究不足
The study may face limitations in the scalability of the synthesis process for GSS NCs and the potential for increased charge recombination in the photoanode due to the incorporation of GSS NCs, which could slightly decrease the open-circuit voltage (Voc).
