In this talk from the 2016 MRS Spring Meeting, Dr. Aditya Mohite of Los Alamos National Lab discusses his group’s recent work n a novel solution-processing technique termed as “hot-casting” to grow continuous, pin-hole free thin-films of organometallic perovskites with millimeter-scale crystalline grains. Photovoltaic devices show hysteresis-free response, with high degree of reproducibility, thus overcoming a fundamental bottleneck for hybrid perovskite devices. Characterization and modeling attribute the improved performance to reduced bulk defects and improved charge-carrier mobility in large-grain devices.
