 Organic inorganic hybrid perovskite materials are gaining increasing attention due to their potential applications in optoelectronics and photovoltaics. However, they have not yet reached the same levels of performance as inorganic perovskites, such as BATRO3. This paper reports on a new material, DMAGEI3, which has ferroelectric properties similar to those of BATRO3, but with higher spontaneous polarization and lower coercive field. The authors attribute this improvement to the combination of the stereochemical activity of the GE2 plus ion and the ordered arrangement of the organic cation. Additionally, the authors show that the material has a low kinetic energy barrier for the movement of small cations, resulting in a low coercive field. These findings suggest that organic inorganic hybrid perovskites can be used to create high-performance ferroelectric materials.
