Unravelling the structural complexity and photophysical properties of adamantyl-based layered hybrid perovskites

Michael Graetzel, Shaik Mohammed Zakeeruddin, Ursula Röthlisberger, Wolfgang Richard Tress, Jovana Milic, Marko Mladenovic, Ulf Anders Hagfeldt, Mohammad Ibrahim Dar, Amita Ummadisingu, Paramvir Ahlawat

Layered hybrid perovskites comprising adamantyl spacer (A) cations based on the A(2)FA(n-1)Pb(n)I(3n+1)(n= 1-3, FA = formamidinium) compositions have recently been shown to act as promising materials for photovoltaic applications. While the corresponding p ...
