Ummadisingu A, Steier L, Seo J, Matsui T, Abate A, Tress W, et al.
Nature . 2017 Apr; 545(7653):208-212. PMID: 28445459
Optimizing the morphology of metal halide perovskite films is an important way to improve the performance of solar cells when these materials are used as light harvesters, because film homogeneity...

Adv Mater . 2017 Jan; 29(15). PMID: 28106931
A room-temperature perovskite material yielding a power conversion efficiency of 18.1% (stabilized at 17.7%) is demonstrated by judicious selection of cations. Both cesium and methylammonium are necessary for room-temperature formamidinium-based...

Saliba M, Matsui T, Domanski K, Seo J, Ummadisingu A, Zakeeruddin S, et al.
Science . 2016 Oct; 354(6309):206-209. PMID: 27708053
All of the cations currently used in perovskite solar cells abide by the tolerance factor for incorporation into the lattice. We show that the small and oxidation-stable rubidium cation (Rb)...

Hadadian M, Correa-Baena J, Goharshadi E, Ummadisingu A, Seo J, Luo J, et al.
Adv Mater . 2016 Aug; 28(39):8681-8686. PMID: 27515231
Controlling the morphology and surface passivation in perovskite solar cells is paramount in obtaining optimal optoelectronic properties. This study incorporates N-doped graphene nanosheets in the perovskite layer, which simultaneously induces...

Saliba M, Matsui T, Seo J, Domanski K, Correa-Baena J, Nazeeruddin M, et al.
Energy Environ Sci . 2016 Aug; 9(6):1989-1997. PMID: 27478500
Today's best perovskite solar cells use a mixture of formamidinium and methylammonium as the monovalent cations. With the addition of inorganic cesium, the resulting triple cation perovskite compositions are thermally...
