Renewable energy sources are being employed more frequently to address energy needs as environmental pollution concerns rise. Photovoltaic (PV) systems are vital in the area of renewable energy sources. We will be able to use a simulation tool to assess the performance and behavior of the PV systems after we obtain experimental data from the systems. Here, the simulation process is carried out by developing a programme in the MATLAB environment based on the experimental data obtained from the fabricated Dye-Sensitized Solar Cells (DSSCs) and allowing users to view the experimental results and characteristic curves on a user-friendly platform like the Graphical User Interface (GUI). The proposed DSSC device achieved an efficiency of 7.38% and an IPCE of 92% at 530 nm, which demonstrates the device’s effectiveness and calibration. Regarding the DSSC parameters and properties, the modeling and experimental findings show good agreement. With this innovative simulation modeling approach, we may gain additional knowledge of the DSSC parameters and validate them with experimental findings.
