The growing requirement for electricity and its inadequate fossil fuel supply is a global concern that's why organic solar cell (OSC) devices had more attraction in the last decades for their practical application. In this research study, GPVDM software is considered, a 3-D photovoltaic device model, used to observe the outcomes of PTB7: PC70BM based organic solar cell. The organic solar cell comprises a PTB7:PC70BM as an active layer, indium tin oxide (ITO) serving as a transparent conducting oxide, and front electrode, PEDOT: PSS for efficient transporting of holes, while Al is taken as a back metal electrode. The electrical simulation via GPVDM has been performed at different active layer thicknesses and charge carrier mobility. Furthermore, the influence of varying different HTM layers had also been studied. The optimum efficiency of OSC is obtained at 200 nm active layer thickness and carrier mobility of 2.46 x 106 m2/Vs. The outcomes and performance of the simulated organic solar cell are compared with the practically implemented organic solar cell. This research also suggests a possible path toward the efficient implementation of organic solar cells by modifying factors that are significantly reliant on the performance and outcomes of OSCs.

<p>The properties of an organic semiconductor are dependent on both the chemical structure of the molecule involved, and how it is arranged in the solid-state. It is challenging to extract the influence of each individual factor, as small changes in the molecular structure often dramatically change the crystal packing and hence solid-state structure. Here, we use calculations to explore the influence of the nitrogen position on the charge mobility of a chiral organic molecule when the crystal packing is kept constant. The transfer integrals for a series of enantiopure aza[6]helicene crystals sharing the same packing were analysed in order to identify the best supramolecular motifs to promote charge carrier mobility. The regioisomers considered differ only in the positioning of the nitrogen atom in the aromatic scaffold. The simulations showed that even this small change in the chemical structure has a strong effect on the charge transport in the crystal, leading to differences in charge mobility of up to one order of magnitude. Some aza[6]helicene isomers that were packed interlocked with each other showed high HOMO-HOMO integrals (up to 70 meV), whilst molecules arranged with translational symmetry generally afforded the highest LUMO-LUMO integrals (40 - 70 meV). As many of the results are not intuitively obvious, a computational approach provides additional insight into the design of new semiconducting organic materials.</p>
