Abstract
Fiber-shaped dye-sensitized solar cells (FDSSCs) represent a promising frontier in solar energy due to their unique flexibility, lightweight form, and adaptability for wearable electronics and integrated textile-based applications. In this study, we aim to enhance the efficiency and cost-effectiveness of FDSSCs by developing a platinum-free counter electrode that maintains high performance under various light conditions. We utilized the hydrothermal method to grow ZnCo2O4 (ZCO) nanostructures on carbon fibers (CF), forming a composite (CF/ZCO) counter electrode as a sustainable alternative to platinum, traditionally used but costly and prone to stability issues. Our FDSSCs with CF/ZCO counter electrodes achieved an efficiency of 8.3 %, demonstrating an 8 % improvement over conventional platinum electrodes. Importantly, these cells retained excellent performance under low-light conditions, achieving more than 9 % efficiency, making them highly suitable for indoor and wearable applications. The high electrocatalytic activity of the CF/ZCO counter electrode was confirmed through electrochemical analyses (EIS, CV, and Tafel polarization), indicating superior charge transport properties over Pt. Structural and morphological characterizations (XRD, Raman, FESEM, HRTEM, and EDS) confirmed the uniformity and quality of the CF/ZCO nanostructures. By replacing platinum with low-cost, non-toxic ZCO, this study contributes to the advancement of sustainable, flexible solar technologies, paving the way for FDSSCs to power next-generation wearable and integrated devices.
