High-performance and high-durability perovskite photovoltaic devices prepared using ethylammonium iodide as an additive

Abstract

Perovskite solar cells display great commercialization potential. Ethylammonium iodide (<bold>EAI</bold>) has been used as an additive for perovskite solar cells. The<bold>EAI</bold>-derived devices displayed enhanced PCEs and long term thermal stability.
