In recent years, new concepts, materials and technologies have dramatically boosted the efficiency of solar cells prepared from solutions. Among these technologies, perovskite solar cells appear as the most promising. However, beside the pure performances of the devices, many bottlenecks remain, the main ones being their cost, their stability and the toxicity of lead halide perovskites. During this seminar, we will give a panorama of our recent achievements related to these points. Our researches, mixing both experimental and theoretical aspects, show the high possibilities, high control and versatility of solution growth techniques for the preparation of materials with desired properties. For the perovskite solar cells, we will illustrate the great importance of the interfaces and selective contact properties for reaching high efficiencies. We will develop our recent results onthe preparation of oxide structures, of new perovskites and of lead-free perovskite related materials. We will also deal with the development of purpose-designed new hole transporting materials. Finally, our results on the use of iodobismuthates for an application as an absorber in perovskite solar cells will be presented.
