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

-

Radiation Laboratory Auditorium

Prof. Vikram Dalal
Distinguished Professor of Engineering
Iowa State University

Abstract:

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.…
