ABSTRACT: Open-air plasmas provide opportunities for versatile and low-cost materials synthesis and film deposition on large and/or complex shapes in laboratory air and at low temperature. The generally solvent-free process further allows for the simultaneous functionalization of, and deposition on, substrates in a single step. Advances in the use of jet plasma process together with precursor spray deposition have further expanded the utility of the deposition technique for a range of multi-functional films.

In this talk I will describe our labs work to develop and demonstrate a scalable open-air plasma process to rapidly deposit and form perovskite cells and modules in open air at fast linear deposition rates. The process uses a combination of reactive species, UV and thermal energy to rapidly form the perovskite film after air spraying, forming high quality perovskite films. I will further mention an indirect laser scribing technique we have developed to efficiently form serially interconnected perovskite cells to form modules along with technoeconomic modeling of module manufacturing costs and LCOE estimates for pilot scale solar installations. I will discuss important aspects related to the stability of perovskite cells and modules and implications for module lifetimes.

Biography: Reinhold H. Dauskardt is the Ruth G. and William K. Bowes Professor of the Department of Materials Science and Engineering, the Department of Mechanical Engineering and the Department of Surgery in the Stanford School of Medicine. He is a Visiting Professor in the School of Materials Science at the Nanyang Technical University in Singapore. He and his research group have worked extensively on integrating new hybrid materials into emerging device, nanoscience, and energy technologies and also on the biomechanical function and barrier properties of human skin and other soft tissues. He is an internationally recognized expert on spray plasma processing of functional thin-films, and on the reliability and damage processes in device technologies and soft tissues, specifically the biomechanics of human skin and regeneration processes in cutaneous wounds. He has won numerous awards including the Henry Maso Award from the Society of Cosmetic Chemists for fundamental contributions to skin science (2011), the IBM Shared University Research Award (2011), the Semiconductor Industry Association University Researcher Award (2010), an IBM Faculty Award (2006), the ASM International Silver Medal (2003), an Alexander von Humboldt Research Award (2002), and the U.S. Department of Energy Outstanding Scientific Accomplishment Award (1989).
