Dye-sensitized solar cells (DSSCs) are sensitized by dyes and are easy to fabricate, low-cost, and non-toxic, which has great potential to be used in photovoltaics. However, the performance of these DSSCs limits their commercial applicability and needs to be investigated. In this work, the photovoltaic properties (short circuit current density (Jsc), open circuit voltage (Voc), fill factor (FF), and power conversion efficiency (PCE)) of the DSSCs have been examined by varying their aperture (Aap) and active (Aac) area at different positions. DSSCs are fabricated with TiO₂ nanoparticles and sensitized with N-719 dye. Fabricated cells and synthesized TiO₂ nanoparticles are characterized by FESEM, XRD, FTIR, UV-DRS spectroscopy, and EIS analysis. The best performance is obtained as PCE ~ 10.47 % and 6.05% for 4 mm² aperture area-based DSSC and 25 mm² active area-based DSSC, respectively. Hence, we have also reported how the efficiency varies as a function of exposed cell area, location of the exposed area, and comparison performance study of active and aperture area-based DSSC. This study will pave the way for a standard testing protocol for DSSCs and their further commercial application
