Seminar Reminder for Matthew Michie's Ph.D. Final Exam. Seminar Wednesday, July 17, at 9:00 a.m., in ARMS 3109; Exam same day at 10:00, in ARMS B197 "Grain Growth Rate Transitions in Barium Strontium Titanate"

Note: this takes place on Wednesday, July 17: Please consider attending the following: MATERIALS ENGINEERING SEMINAR "Grain Growth Rate Transitions in Barium Strontium Titanate" By Matthew J. Michie Purdue MSE Ph.D. Final Exam Advisors: Professor Carol A. Handwerker and Professor John E. Blendell ABSTRACT Understanding grain growth of dielectric ceramics is essential to controlling the electrical and mechanical properties necessary to produce ceramic capacitors and sensors. The effect of alloying barium titanate with strontium titanate on the equilibrium crystal shape is being investigated in order to determine possible impacts on grain growth. The equilibrium crystal shape is being studied through three experimental methods to identify possible changes in the mobility or driving force with changing composition. The first method is by imaging intergranular pores to observe faceting behavior and relative interfacial energies. The second method is to perform atomic force microscopy on surface facets to collect topography data. The topography data is combined with orientation data obtained by EBSD analysis from the same region and is used to calculate the normal vector of the surface facets. The normal vectors are plotted in a stereographic projection to verify the faceting relationships observed in the pore shape analysis. The third method involves collecting EBSD orientation data and images of surface faceting behavior. The surface faceting behavior of each grain is categorized by type of facet and plotted on a stereographic projection at the corresponding orientation. This allows for the analysis of faceting transitions and the differentiation of faceted and continuous regions of the equilibrium crystal shape. The analysis of the equilibrium crystal shape of across compositions has implications on grain growth of the barium titanate/strontium titanate system. Date: Wednesday, July 17, 2019 Time: 9:00 A.M.

by Son, Rosemary E 15 Jul '19

Please consider attending the following: MATERIALS ENGINEERING SEMINAR "Solution Processing of Silver-based Kesterite: from Nanoparticles to Thin Film Solar Cells" By Xianyi Hu Purdue MSE Ph.D. Final Exam Advisors: Professor Carol Handwerker and Professor Rakesh Agrawal ABSTRACT Because of the limited reserve of fossil fuels and issues brought up by their combustion, the demand on renewable energy is considerably increasing. Solar energy is one of the most promising renewable energy sources considering the large amount of solar irradiation received by Earth and solar cell is such a device that allows us to directly convert sunlight directly into electricity. In this thesis, kesterite (I2-II-IV-IV4) system is the main focus as the light absorber material in thin film solar cells. Cu2ZnSn(S,Se)4 (CZTSSe) has been first studied. However, due to the band tailing resulted from Cu-Zn anti-site defects, further improvement on power conversion efficiency of this material is hindered. Substituting Cu with Ag is expected to solve this problem by decreasing this defect density as a result of the high formation energy of Ag-Zn anti-site defects. Herein, different concentration of Ag is used to substitute Cu in the kesterite system through nanoparticle-ink route for the fabrication of light absorber thin films. For Ag-alloying concentration less than 50%, it suggests that the Ag can induce inhomogeneity, secondary phase formation during nanoparticle formation. Moreover, Ag-alloying is shown to enlarge the grain size and reduce film roughness after selenization, which are beneficial for the optoelectronic properties and device performance. Additionally, the synthesis process for kesterite Ag2ZnSnS4 nanoparticles is explored. AZTS nanoparticles are achieved by solvent-thermal reaction. The reaction pathway during reaction is investigated by different material characterization methods to shed light on the Ag-based nanoparticle synthesis. The final obtained nanoparticles have high crystallinity and homogeneous composition, demonstrating great potential as light absorber materials. Furthermore, the sulfide nanoparticles are converted into selenide thin films in Se vapor at elevated temperature (selenization). The selenization conditions, as well as other process parameters, are optimized for the pure phase kesterite AZTSe thin films with large and dense grains. The optoelectronic properties are explored on these films and an initial research already demonstrates a 0.35% power conversion efficiency as the first solution processed AZTSe device. In summary, multiple material characterization techniques are utilized to understand the microstructure evolution, phase transformation and composition change for solution-processed nanoparticles and following thin films. The material characteristics, process methods and film optoelectronic properties are associated for the future analysis and development of kesterite thin films for photovoltaic applications.

Good morning all, I am moving over the next week and I need more boxes and packing material. If you have any boxes, peanuts, bubble wrap or anything like this that you would like to get rid of in your lab or office, I would be happy to take it off your hands. You can bring them to my desk in ARMS 2300 or email me where I can come and pick them up I will be glad to do so. Thank you and happy Friday, Stacey Stacey Coar Secretary/Development Assistant School of Materials Engineering Purdue University Neil Armstrong Hall of Engineering 701 West Stadium Ave. Room 2300 West Lafayette, IN 47907 765-494-4100 scoar(a)purdue.edu<mailto:scoar@purdue.edu>
