Journal ArticleDOI
Ionic transport in hybrid lead iodide perovskite solar cells
Christopher Eames,Jarvist M. Frost,Piers R. F. Barnes,Brian C. O’Regan,Aron Walsh,M. Saiful Islam +5 more
TL;DR: The results of this combined computational and experimental study suggest that hybrid halide perovskites are mixed ionic–electronic conductors, a finding that has major implications for solar cell device architectures.
Journal ArticleDOI
Vectorial electron injection into transparent semiconductor membranes and electric field effects on the dynamics of light-induced charge separation
TL;DR: In this article, the dynamics of charge recombination following electron injection from the excited state of RuL{sub 3} into the conduction band of the semiconductor were examined under potentiostatic control of the electric field within the space charge layer of the membrane.
Journal ArticleDOI
Evidence for ion migration in hybrid perovskite solar cells with minimal hysteresis
Philip Calado,Andrew M. Telford,Daniel Bryant,Xiaoe Li,Jenny Nelson,Brian C. O’Regan,Piers R. F. Barnes +6 more
TL;DR: Transient optoelectronic measurements combined with device simulations indicate that electric-field screening, consistent with ion migration, is similar in both high and low hysteresis CH3NH3PbI3 cells.
Journal ArticleDOI
Electron Transfer Dynamics in Dye-Sensitized Solar Cells
TL;DR: In this article, the materials design parameters that control the processes of charge separation, and thereby device efficiency, in dye-sensitized photoelectrochemical solar cells are discussed.
Journal ArticleDOI
Parameters influencing the efficiency of electron injection in dye-sensitized solar cells.
TL;DR: The relative energetics of the dye excited state versus the titanium dioxide acceptor state is a key determinant of the dynamics of electron injection in DSSC, and that variations in these energetic, and therefore in the kinetics and efficiency of electron injections, impact directly upon device photovoltaic efficiency.
