Journal ArticleDOI
Efficient Hybrid Solar Cells Based on Meso-Superstructured Organometal Halide Perovskites
Michael M. Lee,Joël Teuscher,Tsutomu Miyasaka,Takurou N. Murakami,Takurou N. Murakami,Henry J. Snaith +5 more
TL;DR: A low-cost, solution-processable solar cell, based on a highly crystalline perovskite absorber with intense visible to near-infrared absorptivity, that has a power conversion efficiency of 10.9% in a single-junction device under simulated full sunlight is reported.
Journal ArticleDOI
Overcoming ultraviolet light instability of sensitized TiO 2 with meso-superstructured organometal tri-halide perovskite solar cells
TL;DR: Here, a critical instability in mesoporous TiO₂-sensitized solar cells arising from light-induced desorption of surface-adsorbed oxygen is identified and it is shown that this instability does not arise in mesosuperstructured solar cells.
Journal ArticleDOI
Low-temperature processed meso-superstructured to thin-film perovskite solar cells
TL;DR: In this paper, the bulk absorber layer of CH3NH3PbI3−xClx perovskite solar cells was reduced from 500 to <150 °C and achieved power conversion efficiency up to 12.3%.
Journal ArticleDOI
Excitons versus free charges in organo-lead tri-halide perovskites
Valerio D’Innocenzo,Valerio D’Innocenzo,Giulia Grancini,Marcelo J. P. Alcocer,Marcelo J. P. Alcocer,Ajay Ram Srimath Kandada,Samuel D. Stranks,Michael M. Lee,Guglielmo Lanzani,Guglielmo Lanzani,Henry J. Snaith,Annamaria Petrozza +11 more
TL;DR: Optical spectroscopy is used to estimate the exciton binding energy in the mixed-halide crystal to be in the range of 50 meV, and it is shown that such a value is consistent with almost full ionization of the excitonic population under photovoltaic cell operating conditions.
Journal ArticleDOI
Plasmonic dye-sensitized solar cells using core-shell metal-insulator nanoparticles.
Michael Brown,Teeraporn Suteewong,R. Sai Santosh Kumar,Valerio D’Innocenzo,Annamaria Petrozza,Michael M. Lee,Ulrich Wiesner,Henry J. Snaith +7 more
TL;DR: The spectroscopic investigation indicates that plasmon-enhanced photocarrier generation competes well with plasmons oscillation damping with in the first tens of femtoseconds following light absorption.
