Rational Design of Multidimensional Organic-Inorganic Hybrid Perovskite toward Ambient Processed Efficient and Stable Photovoltaic Devices
Abstract
We propose to develop a rational design model to realize complex multidimensional perovskite composites. We will first develop robust synthetic routes to realize each of the fundamentally different composite structures that are theoretically possible. By using the fundamentally different structural motifs possible in 2D/3D composites, we will identify how composite structure directly contributes to the balance of stability and efficiency. Through molecular engineering, we will enable ambient processing and enhanced charge transport in more complex, three component multidimensional composites. Graphene oxide based compatabilizers will be used to enable the application of carbon electrode, enhancing both stability and efficiency. This will be coupled with optimization of 3D perovskite composition and physical optimization of the 2D/3D interface. With the growth of new material at the interface, we will make the charge funneling that occurs naturally in multidimensional composites work for us by directing carriers directly toward the interface. Through compositional, interfacial, and electrode design, we will simultaneously maximize stability and efficiency of these complex composites to provide a blue-print for the eventual commercialization of highly stable and efficient perovskite solar cells.
