Hybrid halide perovskite crystal structure.

We're actively engaged in cutting-edge research involving 3D hybrid organic-inorganic metal halide perovskites, particularly in the realm of energy conversion applications, notably photovoltaic cells. Our work encompasses a comprehensive exploration of these materials, with a primary focus on understanding how their properties, including crystal phase, luminescence, and morphology, evolve when subjected to varying synthesis conditions. Additionally, we're at the forefront of pioneering novel multimodal approaches to investigate the formation dynamics of perovskite materials and enhance their properties. To accomplish this, we utilize advanced characterization tools such as in situ synchrotron-based Grazing-incidence wide-angle X-ray scattering (GIWAXS) and in-situ Photoluminescence (PL). 

In a complementary research area, we are delving into the world of Spectroelectrochemistry and solid-state electrochemistry to gain insights into the defects within Perovskite solar cells. Our mission is to drive innovation and deepen our understanding of these materials, ultimately contributing to the advancement of sustainable energy technologies.
