The 2017 terahertz science and technology roadmap Dhillon et al. J. Phys. D-Appl. Phys., 50:043001 (Feb 2017) [ pdf ][ DOI:10.1088/1361-6463/50/4/043001 ] Comprehensive roadmap of terahertz science and technology in 2017. This 50 page article reviews that state-of-the-art and predicts future directions or research.	Influence of Interface Morphology on Hysteresis in Vapor-Deposited Perovskite Solar Cells Patel et al. , 3:1600470 (Feb 2017) [ pdf ][ DOI:10.1002/aelm.201600470 ] We use interface engineering to produce highly crystalline perovskite hysteresis-free evaporated planar heterojunction solar cells. TEM reveals that poor interfaces leads to amorphous regions of MAPbI3, hysteresis and poor stabilised power conversion efficiencies.	Broadband phase-sensitive single {InP} nanowire photoconductive terahertz detectors Peng et al. Nano Lett., 16:4925-4931 (Aug 2016) [ pdf ][ DOI:10.1021/acs.nanolett.6b01528 ]
Electron-phonon coupling in hybrid lead halide perovskites Wright et al. Nat. Commun., 7:11755 (May 2016) [ pdf ][ DOI:10.1038/ncomms11755 ] We show by photoluminescence measurements and first-principles calculations that longitudinal optical phonons dominate the electron-phonon coupling at room temperature in hybrid lead halide perovskites.	Increased Photoconductivity Lifetime in GaAs Nanowires by Controlled n-Type and p-Type Doping Boland et al. ACS Nano, 10:4219-4227 (Mar 2016) [ pdf ][ DOI:10.1021/acsnano.5b07579 ] Terahertz spectroscopy of GaAs nanowires with controlled n-type and p-type shell doping, to show enhanced lifetimes due to reduced surface recombination caused by doping-related band bending.	Hybrid Perovskites for Photovoltaics: Charge-Carrier Recombination, Diffusion, and Radiative Efficiencies Johnston et al. Accounts Chem. Res., 49:146--154 (Jan 2016) [ pdf ][ DOI:10.1021/acs.accounts.5b00411 ] A review of the photo physics of Perovskite based semiconductors
