Abstract

Solar energy is a clean and renewable source of energy which is the most promising form of energy for the future. Solar energy can be converted to electrical energy through solar cells which are made up of inorganic and/or organic materials. Bulk heterojunction solar cells which are made up of intermixed blend of polymer and fullerene materials are potential solar cells because of their light weight, flexibility and low manufacturing cost. Simulation models and software for modelling solar cells are also being developed that solve some equations and address some of the physical phenomenon. However, much more realistic models for organic solar cells needs to be developed that can simulate organic materials for solar cells. This thesis presents a P3HT: PCBM solar cell model based on Kinetic Monte Carlo simulation and studies the morphological variation of the model and its effects on JV behavior of solar cells. Similar parameters variations are applied to real fabricated P3HT:PCBM organic solar cells in the laboratory and the results are compared for the validation of the model. Basically, three morphological parameters including domain size, donor/acceptor site ratio and thickness of active layer are taken into account for the simulation. Similarly, three fabrication parameters such as annealing temperature, donor/acceptor weight ratio and spin coating speed are varied to observe the variation of performance of real fabricated cells. The xvi optimized parameters of simulation and fabrication are correlated and the simulation results are in agreement with the experimental results.
