NDRl Seminar: Vapor deposited perovskite cells: Electronic properties and structural stability


Radiation Laboratory Auditorium

Prof. Vikram Dalal
Distinguished Professor of Engineering
Iowa State University


Perovskite solar cells are clearly the new frontier in solar energy conversion. They have the potential of significantly increasing the efficiency of crystalline Si solar cells to 30% range when used in a tandem cell arrangement. In this talk, I will discuss an all vapor-phase deposition process for making perovskite cells, and the detailed electronic properties of perovskite cells deposited using both methyl ammonium iodide and formamine iodide  precursors. I will discuss the fundamental thermally-induced structural instability of both material systems. Both n-i-p and p-i-n types of cells will be described along with the relative advantages of each type.…
