Three-dimensional cross-nanowire networks recover full terahertz state Peng et al. Science, 368:510--513 (May 2020) [ pdf ][ DOI:10.1126/science.abb0924 ] We have developed a new nanowire-based THz sensor that recovers the full state of THz pulses.	Trap states, electric fields, and phase segregation in mixed-halide perovskite photovoltaic devices Knight et al. Adv. Energy Mater., 10:1903488 (Mar 2020) [ pdf ][ DOI:10.1002/aenm.201903488 ]	Light absorption and recycling in hybrid metal halide perovskite photovoltaic devices Patel et al. Adv. Energy Mater., 10:1903653 (Mar 2020) [ pdf ][ DOI:10.1002/aenm.201903653 ] We use vapour co-deposition to control precisely the thickness of perovskite films, and study the effect of light management in thin film solar cells
Control over Crystal Size in Vapor Deposited Metal-Halide Perovskite Films Lohmann et al. ACS Energy Lett., 5:710-717 (Mar 2020) [ pdf ][ DOI:10.1021/acsenergylett.0c00183 ] We have developed a method to control crystal size when vapour depositing metal halide perovskite semiconductors	Impurity Tracking Enables Enhanced Control and Reproducibility of Hybrid Perovskite Vapor Deposition Borchert et al. ACS Appl. Mater. Interfaces, 11:28851-28857 (Jul 2019) [ pdf ][ DOI:10.1021/acsami.9b07619 ] Our results indicate that as long as precursor deposition rates are well controlled, physical vapor deposition will allow high solar cell device yields even if the purity of precursors changes from one run to another.	Solution-processed all-perovskite multi-junction solar cells McMeekin et al. Joule, 3:387-401 (Feb 2019) [ pdf ][ DOI:10.1016/j.joule.2019.01.007 ]
