摘要

This study demonstrates the fabrication of TiO₂-based photoanodes for dye-sensitized solar cells (DSSCs) with the incorporation of reduced graphene oxide (rGO) at varying weight percentages (0.5, 1, and 3 wt%) using a direct and straightforward approach. In this work, rGO was synthesized using a simple, cost-effective, and environmentally friendly method previously reported in the literature, offering an alternative to conventional Hummers and modified Hummers methods. Systematic structural, morphological, compositional, and optical studies confirmed the incorporation of rGO on TiO₂ films. The power conversion efficiency (PCE) of DSSCs improved with rGO incorporation, with the optimal concentration identified as 1 wt%. Electrical conductivity measurements revealed that rGO incorporation enhanced conductivity, while electrochemical impedance spectroscopy (EIS) analysis indicated reduced charge transfer resistance, leading to suppressed recombination and improved electron transport. Additionally, incident photon-to-current efficiency (IPCE) measurements confirmed the enhanced efficiency of the 1 wt% rGO-incorporated sample. The simplicity and sustainability of the rGO synthesis method, along with the direct integration approach, highlight the potential of rGO as an effective and practical additive for enhancing the performance of DSSCs.
