Influence of the Subcell Properties on the Fill Factor of Two-Terminal Perovskite-Silicon Tandem Solar Cells

Christophe Ballif, Mathieu Gérard Boccard

The performance of a tandem solar cell depends on the performance of its constituting subcells. Although this dependency is theoretically straightforward for open-circuit voltage (V-oc) and short-circuit current, it is indirect for fill factor (FF) and thu ...

Tower and Path-Dependent Voltage Effects on the Measurement of Grounding Impedance for Lightning Studies

Marcos Rubinstein, Antonio Sunjerga, Hamidreza Karami, Keyhan Sheshyekani

We present an analysis aimed at evaluating the effect of the presence of the tower on the measurement of the grounding impedance. The Numerical Electromagnetics Code NEC-4 is used for the full-wave modeling of the structure including the tower and its foot ...

A partially-planarised hole-transporting quart-p-phenylene for perovskite solar cells

Shaik Mohammed Zakeeruddin, Wolfgang Richard Tress, Michael Saliba

Herein, we describe the synthesis of a hole transporting material based on a partially planarised quart-p-phenylene core incorporating tetraketal and diphenylamine substituents that show optimal energy levels and solubility for perovskite solar cell applic ...

Molecular Engineering of Simple Metal-Free Organic Dyes Derived from Triphenylamine for Dye-Sensitized Solar Cell Applications

Michael Graetzel, Shaik Mohammed Zakeeruddin, Farzan Jazaeri, Yuhang Liu, Parnian Ferdowsi, Ulf Anders Hagfeldt, Yasemin Saygili

Two new metal-free organic sensitizers, L156 and L224, were designed, synthesized, and characterized for application in dye-sensitized solar cells (DSCs). The structures of the dyes contain a triphenylamine (TPA) segment and 4-(benzo[c][1,2,5]thiadiazol-4- ...

Transient Impedance of Interconnected Wind Turbine Grounding Systems

Marcos Rubinstein, Antonio Sunjerga, Qi Li

Wind turbines are very vulnerable to lightning because of their height, sharp edges and remote locations often with low soil conductivity. In this paper we present numerical simulations of the impedance of a typical wind turbine grounding geometry. We anal ...

Insights into photovoltaic properties of ternary organic solar cells from phase diagrams

Roland Hany, Jakob Heier, Philippe Schwaller, Surendra Babu Anantharaman

The efficiency of ternary organic solar cells relies on the spontaneous establishment of a nanostructured network of donor and acceptor phases during film formation. A fundamental understanding of phase composition and arrangement and correlations to photo ...

A Timing-Monitoring Sequential for Forward and Backward Error-Detection in 28 nm FD-SOI

Andreas Peter Burg, Adam Shmuel Teman, Andrea Bonetti, Jeremy Hugues-Felix Constantin

The increasing impact of variability on near-threshold nanometer circuits calls for a tighter online monitoring and control of the available timing margins. Error-detection sequentials are widely used together with error-correction techniques to operate di ...

Fault Detection and Faulted Line Identification in Active Distribution Networks Using Synchrophasors-based Real-Time State Estimation

Mario Paolone, Paolo Romano, Marco Pignati, Lorenzo Zanni

We intend to prove that PMU-based state estimation processes for active distribution networks exhibit unique time determinism and refresh rate that make them suitable to satisfy the time-critical requirements of protections as well as the accuracy requirem ...

Intrinsic and interfacial kinetics of perovskite solar cells under photo and bias-induced degradation and recovery

Shaik Mohammed Zakeeruddin, Pankaj Kumar Yadav, Daniel Prochowicz, Essa Awadh R Alharbi

Perovskite solar cells (PSCs) have emerged as a potential candidate for high efficiency low-cost photovoltaic technology. However, the intrinsic and interfacial responses of PSCs under photo and bias-induced degradation and recovery have not been clearly u ...
