Congratulations to Dr. Xinting Shuai for completing his PhD on “Morphology controlled All-Inorganic 2D Perovskite and Transition-Metal Dichalcogenides materials synthesis, characterization and application”. He was co-advised by Prof. Pulickel Ajayan and Prof. Aditya Mohite. He will be continuing his work as a post-doc at the Ajayan Lab….
Chika Okolo, an NSF RET Program teacher, worked with us over the summer to understand the fabrication of perovskite solar cells and how to incorporate them into high school teaching! He presented his work on understanding halide perovskite solar cells and optimizing hole transport layers at the Rice Engineering STEM symposium!…
Austin, Ayush, and Faiz worked on developing a novel barrier called the conductive adhesive barrier (or CAB) to protect the surface of the perovskite photoabsorber from electrolyte corrosion while retaining the charge collection efficiency by >99%. This enables the use of halide perovskite solar cells as photoelectrochemical cells that can directly convert sunlight to hydrogen…
Siraj Sidhik becomes the first student to graduate from the MPEM lab after spending more than 5 years with our lab! He will soon be joining Cubic PV to continue his efforts in making high-efficiency and stable perovskite solar cells! Congratulations, Dr. Siraj!…
Ayush and Austin attended the MRS Spring 2023 held in San Francisco, California, to represent the MPEM group. Ayush gave his first oral presentation on synthesizing 2D perovskites for solar cells, and Austin presented a poster on H2 production using perovskite photoelectrochemical cells….
Hao Zhang demonstrated a direct visualization of the carrier-lattice interactions in 2D halide perovskites for the first time. He did this by directly probing the lattice degrees of freedom in ps time scale using the ultrafast electron diffraction technique (MeV-UED) following the above bandgap high-density photoexcitation. Upon illumination, he observed a novel lattice behavior involving…
This award is presented to Dr. Aditya Mohite of Rice University for achieving an integrated halide perovskite photoelectrochemical cell with record-setting solar-driven water-splitting efficiency of 20.8%. Mohite’s system exhibited extended durability due to a novel graphite anticorrosion barrier that translates >99% of photoelectric power directly to hydrogen production. His work increasing the durability and efficiency…
Graduate students Hao Zhang and Siraj Sidhik presented their work on creating phase pure 2D hybrid halide perovskites and understanding their light-induced ultrafast lattice ordering at the Unconventional Semiconductors. Hao was also among the best poster presenters during the 4-day conference!…
Dr. Mohite spoke about the work in the lab over the past five years on 2D-HaPs ranging from the fundamental light-induced structural behaviors, and solvation dynamics to control homogeneity of layer thickness, novel photo-physical behaviors, and charge transport and their role in the high-efficiency optoelectronic device, with technologically relevant durability. He also presented key challenges…
Andrew Torma is a 3rd year PhD student in the Applied Physics Program. He recently defended his master’s thesis on “Nanoimaging to Determine the interstitial nature of Mn(II) doping in 2D halide perovskites”…
