Organic photovoltaic (OPV) cells are state-of-the-art, freshly developing technologies, lightweight, mechanically flexible devices with elevated processes in a range of shades. A OPV cell based on nanostructures. Our project presents the model and the simulation of a widespread photovoltaic system capable of predicting solar array performance under different environmental circumstances. The simulation was conducted in Matlab/Simulink and gives crucial electrical features including cell I-V and efficiency information when inputting cell parameters. The whole simulated system has three elements: a universal two-cell solar array capable of partial production changes, a current-controlled converter and a charging and discharging energy storage device.
