报告摘要

In recent years, perovskite solar cells appeared the most promising candidate for the 3rd generation photovoltaic device due to their favorable performance. However, beside the pure high performances of these devices, many bottlenecks remain, the main ones being their cost, their stability, the toxicity of lead halide perovskites and the understanding of their electrical response. During this seminar, we show the high possibilities, high control and versatility of the solution growth techniques for the preparation of materials with desired properties. And the great importance of the interfaces and selective contact properties for reaching high efficiencies perovskite solar cells will be illustrated. We also focus on the preparation of oxide structures, of highly efficient pure phase perovskites, on the effect of doping the hole transporting material (HTM) and on the development of new HTMs. In every case, Impedance spectroscopy studies will be discussed to expound and discriminate the bulk and interface effects. Finally, we will discuss the new lead-deficient perovskite family and lead-free perovskite.
