Synthesis and Deposition
Our laboratory is dedicated to the synthesis and deposition of advanced energy materials, focusing on perovskites (2D and 3D) and chalcogenides. We explore their properties in diverse forms, such as thin-films, powders, and solutions, optimizing their potential for cutting-edge technological applications. We employ a wide array of techniques for material synthesis and thin-film deposition. These include solution-based methods like hot-injection, hydrothermal synthesis, precipitation methods and direct preparation of molecular complexes for ink formulation and deposition. By appropriate tailoring of these techniques, we prepare bulk and nanomaterials of different dimensions; including quantum dots, nano-wires, nano-sheets and three-dimensional structures of diverse morphologies. For thin-film fabrication, we utilize techniques like spin-coating, electrophoretic deposition, chemical bath deposition and thermal evaporation.
Using a state-of-the-art glove box, we establish synthesis conditions requiring an inert atmosphere, ensuring high-quality material preparation. Some of our published works demonstrate the synthesis of binary and ternary chalcogenides and 2D perovskites with tailoring them for different photovoltaic applications.1,2
