Influence of the Hole Transporting Layer on the Thermal Stability of Inverted Organic Photovoltaics Using Accelerated Heat Lifetime Protocols
Felix Hermerschmidt, Achilleas Savva, Efthymios Georgiou +7
High power conversion efficiency (PCE) inverted organic photovoltaics (OPVs) usually use thermally evaporated MoO3 as a hole transporting layer (HTL). Despite the high PCE values r…
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, Phil Calado +9
Mobile ions in hybrid perovskite semiconductors introduce a new degree of freedom to electronic devices suggesting applications beyond photovoltaics. An intuitive device model desc…
Identifying dominant recombination mechanisms in perovskite solar cells by measuring the transient ideality factor
Phil Calado, Dan Burkitt, Jizhong Yao +7
The ideality factor determined by measuring the open circuit voltage (VOC) as function of light intensity is often used as a means to identify the dominant recombination mechanism…
