研究目的
Investigating the structural, optical, and physical properties of diamond-like carbon (DLC) films fabricated by using a filtered vacuum arc (FVA) method for application as anti-reflection coatings in dye-sensitized solar cells (DSSCs) to improve their performance.
研究成果
The DLC films fabricated using the FVAS method showed improved structural, optical, and physical properties with increasing film thickness. These improvements are attributed to the increased sp3 content in the films due to energetic ion bombardment during deposition. The films' application as anti-reflection coatings in DSSCs showed potential for improving cell efficiency, with the best performance observed for a 100-nm-thick DLC film.
研究不足
The study focuses on the properties of DLC films and their application as anti-reflection coatings in DSSCs. The limitations include the specific conditions under which the films were fabricated and the range of film thicknesses investigated. Potential areas for optimization include the deposition process and the film properties to further improve DSSC performance.
1：Experimental Design and Method Selection:
The DLC films were fabricated using a filtered vacuum arc system (FVAS) with a graphite target source. The structural, optical, and physical properties of the films were investigated.
