Synchronizing Crystallization Enables Thermally Stable All-FA Pb-Sn Perovskites for Printable MA-Free All-Perovskite Tandem Solar Cells

HLH. LiJinan University WFWei FengJinan University JWJianan WeiJinan University

Key Points

The aim is to improve thermal stability in Pb-Sn perovskites for solar cell applications by eliminating methylammonium.
Developed a synchronization technique for crystallization
Created all-FA (formamidinium) perovskite layers
Evaluated thermal stability and performance of the solar cells
Achieved thermally stable perovskite structures
Demonstrated improved solar cell efficiency
Eliminated the need for volatile methylammonium

Abstract

Monolithic all-perovskite tandem solar cells based on mixed cation lead-tin (Pb-Sn) have advanced rapidly in recent years. However, the presence of a considerable amount of volatile methylammonium (MA) adversely constrains...
