Abstract
This study enhances quantum dot‐sensitized solar cells (QDSSCs) with a photoanode containing gold and silver nanoparticles in a diamond‐like carbon (DLC) matrix. The nanoparticles exhibit a synergistic effect, increasing the photoanode's response to visible light through localized surface plasmon resonance (LSPR). Simulations show that these nanoparticles improve charge transfer and cell efficiency by creating additional electron traps. DLC acts as a shield, protecting silver nanoparticles from corrosion, thus enhancing cell stability. The modified photoanode significantly increases the short‐circuit current density compared to the standard photoanode, confirming the simulation results and demonstrating the potential for improved solar cell performance.
