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
Toward Stretchable Self-Powered Sensors Based on the Thermoelectric Response of PEDOT:PSS/Polyurethane Blends
Prospero J. Taroni,Giovanni Santagiuliana,Kening Wan,Philip Calado,Manting Qiu,Han Zhang,Nicola M. Pugno,Nicola M. Pugno,Matteo Palma,Natalie Stingelin-Stutzman,Martin Heeney,Oliver Fenwick,Mark Baxendale,Emiliano Bilotti +13 more
TL;DR: In this paper, a stretchable self-powered sensor with poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) is presented.
Journal ArticleDOI
Interpretation of inverted photocurrent transients in organic lead halide perovskite solar cells: proof of the field screening by mobile ions and determination of the space charge layer widths
Rebecca A. Belisle,William H. Nguyen,Andrea R. Bowring,Philip Calado,Xiaoe Li,Stuart J. C. Irvine,Michael D. McGehee,Piers R. F. Barnes,Brian C. O’Regan +8 more
TL;DR: In this article, the authors show that the photocurrent transients are reversed in sign (i.e. inverted), and the magnitude of the inverted transients can be used to find an upper bound on the width of the space charge layers adjacent to the electrodes.
Journal ArticleDOI
Identifying Dominant Recombination Mechanisms in Perovskite Solar Cells by Measuring the Transient Ideality Factor
Philip Calado,Dan Burkitt,Jizhong Yao,Joel Troughton,Trystan Watson,Matthew J. Carnie,Andrew M. Telford,Brian O'regan,Jenny Nelson,Piers R. F. Barnes +9 more
TL;DR: In this paper, the authors used drift-diffusion simulations to identify the dominant recombination mechanism in perovskite solar cells (PSCs) following device preconditioning with a forward bias.
Journal ArticleDOI
Ionic-to-electronic current amplification in hybrid perovskite solar cells: ionically gated transistor-interface circuit model explains hysteresis and impedance of mixed conducting devices
Davide Moia,Ilario Gelmetti,Philip Calado,William Fisher,Michael Stringer,Onkar Game,Yinghong Hu,Pablo Docampo,Pablo Docampo,David G. Lidzey,Emilio Palomares,Jenny Nelson,Piers R. F. Barnes +12 more
TL;DR: In this article, the perovskite-contact interfaces are described as transistors which couple ionic charge redistribution to energetic barriers controlling electronic injection and recombination, revealing an amplification factor between the out of phase electronic current and the ionic current.
