Photovoltaic switching mechanism in lateral structure hybrid Perovskite solar cells

August 5, 2015
Author(s)
Yongbo Yuan, Jungseok Chae, Yuchuan Shao, Qi Wang, Zhengguo Xiao, Andrea Centrone, Jinsong Huang
Organometal trihalide perovskite solar cells with lateral device architecture recently attracted interest because of their switchable photovoltaic effect, which potentially could be leveraged to realize transparent-electrode-free solar cells. However, the

Unique para-effect in electron ionization mass spectra of bis(perfluoroacyl) derivatives of bifunctional aminobenzenes

September 15, 2010

Kirill V. Tretyakov, Nino G. Todua, Roman S. Borisov, Vladimir G. Zaikin, Stephen Stein, Anzor I. Mikaia
A new kind of "para-effect" under EI conditions has been discovered for a series of bis(perfluoroacyl) derivatives of o-, m- and p- phenylendiamines, hydroxybenzeneamines and mercaptobenzeneamines of a common structure RCOX C 6H 4 NHCOR (X = NH, S, O; R =

Diffusion in Partially Saturated Porous Materials

October 1, 1999
Author(s)
Nicos Martys
The diffusive transport of ions in two classes of porous media was studied as a function of fluid saturation and wetting properties. A lattice Boltzmann method was used to model phase separation of a binary mixture, including wetting effects, in porous
