Extraction of different parameters of hybrid solar cell based on PVK/Silicon nanowires

Solar cell based on conjugated polymer-inorganic semiconductor are often designed to be structured in hybrid solar cell in objective to supply a large interface area for exciton dissociation. The main objective of this paper is to extract four electrical parameters such as the saturation current, the series resistance, the ideality factor and the shunt resistance from the measured current-voltage characteristics in different conditions of annealing temperatures, annealing times, the weight ratio of Silicon nanowires, the thickness of photoactive layer and the treatment of Silicon nanowires with a fluorhydric acid solution HF for which hybrid solar cell had the best electrical properties. These parameters are extracted to simulate the current-voltage of solar cell based on a thin film blend of Poly (N-vinylcarbazole) (PVK) and Silicon nanowires (SiNWs). A good agreement between theoretical model and experimental measurement of electrical characteristics is obtained which illustrates the improvement that can supply the variation of different conditions on the characteristics of solar cells based on PVK/SiNWs.
