Dimethylammonium additives alter both vertical and lateral composition in halide perovskite semiconductors
Sarthak Jariwala, Rishi Kumar, Giles E. Eperon +3
Adding a large A-site cation, such as dimethylammonium (DMA), to the perovskite growth solution has been shown to improve performance and long-term operational stability of halide…
Relaxed current matching requirements in highly luminescent perovskite tandem solar cells and their fundamental efficiency limits
Alan R. Bowman, Felix Lang, Yu-Hsien Chiang +8
Here we use time-resolved and steady-state optical spectroscopy on state-of-the-art low- and high-bandgap perovskite films for tandems to quantify intrinsic recombination rates and…
Approaching the limits of optoelectronic performance in mixed cation mixed halide perovskites by controlling surface recombination
Sarthak Jariwala, Sven Burke, Sean Dunfield +7
We demonstrate the critical role of surface recombination in mixed-cation, mixed-halide perovskite, FA0.83Cs0.17Pb(I0.85Br0.15)3. By passivating non-radiative defects with the poly…
Microseconds, milliseconds and seconds: deconvoluting the dynamic behaviour of planar perovskite solar cells
Adam Pockett, Giles Eperon, Nobuya Sakai +3
Perovskite solar cells (PSC) are shown to behave as coupled ionic-electronic conductors with strong evidence that the ionic environment moderates both the rate of electron-hole rec…
Perovskite-perovskite tandem photovoltaics with optimized bandgaps
Giles E. Eperon, Tomas Leijtens, Kevin A. Bush +24
We demonstrate four and two-terminal perovskite-perovskite tandem solar cells with ideally matched bandgaps. We develop an infrared absorbing 1.2eV bandgap perovskite, $FA_{0.75}Cs…
Spatially resolved studies of the phases and morphology of methylammonium and formamidinium lead tri-halide perovskites
K. Galkowski, A. Mitioglu, A. Surrente +8
The family of organic-inorganic tri-halide perovskites including MA (MethylAmmonium)PbI, MAPbICl, FA (FormAmidinium)PbI and FAPbBr are having a trem…
