SUMMARY:Halide Perovskites: new materials for optoelectronic devices
DESCRIPTION:Organometal Halide Perovskites such as MethylAmmonium Lead Iodide are opening new opportunity for solution-process high performing optoelectronic devices such as solar cells\, photodetectors\, light-emitting diodes etc. The success of such materials is based on the ideal direct band gap\, good electron and hole diffusion lengths and the easy manufacture. Moreover\, tuning of electronic and optical properties can be achieved by varying cation composition (Cs\, Rb\, FA\, MA etc.) and halide composition (I\, Br\, Cl). One of the most successful  application of such materials is in the field of solar cell where a certified efficiency of 22.7% has been achieved for single cells and 27.3% for tandem perovskite/silicon.  I this talk I will review the main characteristics of the halide perovskites and the application to conventional optoelectronic devices showing possible applications in the field of high-energy physics.
