Based on current energy and environmental context, research in the photovoltaic field is growing very fast. Silicon photovoltaic (PV) cells dominate the world market. One of the reasons limiting the efficiency of silicon-based solar cells are the losses due to thermalization. Multi-junction cells represent a solution to reduce these losses, but they are expensive too. The printing technique, therefore represents a viable alternative for it is a low temperature and a low-cost technique. Moreover, it can be realized on flexible devices and with unlimited raw material. The objectives of this thesis are thus to firstly realize perovskite solar cells using the Slot Die printing technique and then to optimize it to optimize a 4-terminal (4T) tandem silicon/perovskite cell. A simulation study by SETFOS (Semiconducting Emission Thin Film Optics Simulation) was made to understand and optimize the effect of thickness, mobility of charge carriers and bands energy on the efficiency of the perovskite solar cell. Then, a characterization of the absorption coefficient of other layers inside the cells were made using Lambda 750 UV / Vis / NIR and X-ray diffraction technique (XRD) were used to optimize the temperature and the annealing time of the perovskite film. The last part of this work was reserved to the study of the effects of the layers of the perovskite cell on the absorption of the mono-crystalline silicon cell. This experimental study allowed us to optimize the layers of the perovskite solar cell and to evaluate the feasibility of having a perovskite/silicon tandem solar cell.
