Perovskite Deposition and Characterization Station at Controlled Environment
Abstract
The promise of high-throughput, low-cost electronics manufacturing is highly relevant for consumer and defense products, including energy-generating devices, shock-resistant flexible displays, and lighting applications, as well as various sensor technologies. While over the last two decades organic materials have dominated the field of solutionprocessed electronics, hybrid organic-inorganic metal halides with a perovskite structure have more recently emerged as a highly promising, tremendously versatile materials platform reaching power conversion efficiencies of 22% in solar cells, and having shown exciting results when used in solution-processed light-emitting technologies, electrically pumped lasers, and sensors. To accelerate our understanding of this materials class and the complex processing/property/device performance interrelation, we propose here to establish a deposition and characterization station with controlled environment for a broad variety of metal halide perovskite materials (i.e., organic/inorganic hybrids and all inorganic perovskites). The requested instrumentation will enable us to provide unique insights into film evolution during solution deposition as well as post-deposition processes (e.g., device fabrication), and permit us to correlate these insights with the optoelectronic properties and device performance of the final architectures. Such knowledge is required to design materials from the outset, and to deposit these rather unique materials reproducibly with high yield. We will build for this purpose a deposition and characterization station that is based on two interconnected gloveboxes, which will enable solution-deposition of metal halide films and necessary post-deposition procedures needed for device fabrication. A spectroscopic characterization platform will be connected to this system to obtain information of film quality.
