The electronic disorder landscape of mixed halide perovskites
Yun Liu, Jean-Philippe Banon, Kyle Frohna +5
Bandgap tunability of lead mixed-halide perovskites makes them promising candidates for various applications in optoelectronics since they exhibit sharp optical absorption onsets d…
Efficient all-perovskite tandem solar cells by dual-interface optimisation of vacuum-deposited wide-bandgap perovskite
Yu-Hsien Chiang, Kyle Frohna, Hayden Salway +4
Tandem perovskite solar cells beckon as lower cost alternatives to conventional single junction solar cells, with all-perovskite tandem photovoltaic architectures showing power con…
Local Nanoscale Defective Phase Impurities Are the Sites of Degradation in Halide Perovskite Devices
Stuart Macpherson, Tiarnan A. S. Doherty, Andrew J. Winchester +12
Halide perovskites excel in the pursuit of highly efficient thin film photovoltaics, with power conversion efficiencies reaching 25.5% in single junction and 29.5% in tandem halide…
Nanoscale Chemical Heterogeneity Dominates the Optoelectronic Response over Local Electronic Disorder and Strain in Alloyed Perovskite Solar Cells
Kyle Frohna, Miguel Anaya, Stuart Macpherson +7
Halide perovskites perform remarkably in optoelectronic devices including tandem photovoltaics. However, this exceptional performance is striking given that perovskites exhibit dee…
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…
