Organohalide Lead Perovskites for Photovoltaic Applications

Perovskite solar cells have recently exhibited a significant leap in efficiency due to their broad absorption, high optical absorption coefficient, very low exciton binding energy, long carrier diffusion lengths, efficient charge collection, and very high ...

Mobile phone data highlights the role of mass gatherings in the spreading of cholera outbreaks

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Flavio Finger

The spatiotemporal evolution of human mobility and the related fluctuations of population density are known to be key drivers of the dynamics of infectious disease outbreaks. These factors are particularly relevant in the case of mass gatherings, which may ...

Spectral methods for tempered fractional differential equations

Jan Sickmann Hesthaven, Lijing Zhao

In this paper, we first introduce fractional integral spaces, which possess some features: (i) when 0 < α < 1, functions in these spaces are not required to be zero on the boundary; (ii)the tempered fractional operators are equivalent to the Riemann-Liouvi ...

Fluid injection in a frictional weakening fracture

Brice Tanguy Alphonse Lecampion, Federico Ciardo

Understanding the mechanism of nucleation of dynamic rupture is an important issue in seismology since it is the key factor in determining the seismic potential of pre-existing faults under long-term loadings. Furthermore, the activation of Mode II crack b ...

Exciton dynamics at a single dislocation in GaN probed by picosecond time-resolved cathodoluminescence

Nicolas Grandjean, Jean-François Carlin, Benoît Marie Joseph Deveaud, Gwénolé Jean Jacopin, Wei Liu

We investigate the dynamics of donor bound excitons (D degrees X-A) at T = 10K around an isolated single edge dislocation in homoepitaxial GaN, using a picosecond time-resolved cathodoluminescence (TR-CL) setup with high temporal and spatial resolutions. A ...

Copper Phenanthroline as a Fast and High-Performance Redox Mediator for Dye-Sensitized Solar Cells

Michael Graetzel, Fabrizio Giordano, Ulf Anders Hagfeldt, Yan Hao, Marina Freitag

The most commonly used redox mediators in dye-sensitized solar cells (DSCs), iodide/triiodide and cobalt trisbipyridine (Co(bpy)(3)), were successfully replaced by bis (2,9-dimethy1-1,10-phenanthroline) copp er (I/H) (Cu(dmp)(2)). The use ...

Multilayer four-flux matrix model accounting for directional-diffuse light transfers

Roger Hersch, Mathieu Hébert

The four-flux model is a method to solve light radiative-transfer problems in planar, possibly multilayer structures. The light fluxes are modeled as two collimated and two diffuse beams propagating forward and backward perpendicularly to the layer stack. ...

Learning Network Structures from Firing Patterns

Martin Vetterli, Amin Karbasi, Amir Hesam Salavati

How can we decipher the hidden structure of a network based on limited observations? This question arises in many scenarios ranging from social to wireless and to neural networks. In such settings, we typically observe the nodes’ behaviors (e.g., the time ...
