Our new paper, “Two-dimensional perovskite templates for durable, efficient formamidinium perovskite solar cells,” is now online onScience. In this paper, Isaac and Dr. Sidhik present a design strategy for fabricating ultrastable phase-pure films of formamidinium lead iodide by lattice templating using specific two-dimensional perovskites with FA as the cage cation. We thank all our collaborators…
Four students from the MPEM group received their doctorate degrees and were hooded by Dr. Mohite at the Rice graduation ceremony. We will surely miss them at Rice!…
Faiz Mandani, 4th year PhD student in the MPEM group presented his work on the CAB-enabled solar hydrogen production at the annual REINVENTS conference and won the poster competition….
Dr. Hou is the fifth student to graduate from Dr. Mohite’s group. He successfully defended his work on “Synthesis of 2D Halide perovskite via kinetic and thermodynamic control.” He will pursue a postdoc at Northwestern University under Dr. Ted Sargent and Dr. Bin Chen on perovskite tandem solar cells! We wish him the best of…
Congratulations to Hao Zhang from the Applied Physics Program for successfully defending his thesis on Studying exciton photo-physics in 2D halide perovskites! He will continue to work with the Woodside-Rice Decarbonization accelerator program to study the conversion of CO2 and CH4 to carbon products….
Congratulations to all the members of the MPEM group who presented at the 2023 MRS FALL meeting in Boston in November! Lots of great talks by everyone in the perovskite community and intriguing discussions with students and professors alike!…
In this paper, Jin demonstrated a general method to synthesize 2D perovskites of desired layer thickness through gradual transformation from low n-value to higher n-value by tuning the temperature or time of the crystallization. It addresses the bottleneck of producing stable 2D halide perovskite with ahigh quantum-well number (n=1-6). Also, this work indicates that kinetics control…
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…
