This paper studies various carbon-based nanoparticles, such as fullerene and porphyrin nanoparticles, for use in OPV cells. These nanoparticles offer unique properties, such as high conductivity, high surface area, and tunable band gap, which can be harnessed to optimize the performance of the OPV cell. One of the main challenges with using nanoparticles in OPV cells is their tendency to degrade their stability and long-term performance.
This paper investigates the optimization energy to stabilize nanoparticles to overcome this challenge. Another important factor considered in this paper is the activity of the nanoparticles, which can affect the electrical efficiency of the OPV cell. Nanoparticles can be used as electron donors, electron acceptors, or charge transport materials in the photoactive layer of the OPV cell. This research shows how the choice of nanoparticle and its properties affect the efficiency and stability of the device.
To determine the theoretical values of a specific structure’s atomic properties, such as optimized energy, bond strength, and electron distributions, the Density Functional Theory (DFT) is used. The software used in this paper allows users to build virtually any molecule and optimize its geometry according to various force field options.
