Reorganization energy for hole and electron transfer of poly(3-hexylthiophene) derivatives
(2016-09-02)
Poly(3-hexylthiophene) (P3HT) is a common material used as electron donor element in active layers of organic solar cells. Previous studies have shown that is possible to improve the electronic properties of the P3HT through ...
Thermoelectric transport coefficients from charged Solv and Nil black holes
(Springer, 2017-12)
In the present work we study charged black hole solutions of the EinsteinMaxwell action that have Thurston geometries on its near horizon region. In particular we find solutions with charged Solv and Nil geometry horizons. ...
New Class of Organic Hole-Transporting Materials Based on Xanthene Derivatives for Organic Electronic Applications
(2017-06-22)
In this work, we investigate the influence of three novel 14-aril-14H-dibenzo[a,j]xanthene derivatives (XDs) modified with different functional groups as very promising hole-transporting materials for organic optoelectronic ...
Analysis of the power conversion efficiency of perovskite solar cells with different materials as Hole-Transport Layer by numerical simulations
(Academic Press Ltd - Elsevier Science Ltd, 2017-07)
In this paper, a theoretical study of different p-p-n perovskite solar cells has been performed by means of computer simulation. Effects of the offset level upon the power conversion efficiency (PCE) of these devices have ...
Impedance spectroscopy study of solid-state dye-sensitized solar cells with varying Spiro-OMeTAD concentration
(2010-12-01)
This work reports on the changes of performance of solid-state cells dye-sensitized solar cells with the variation of concentration of spiro-OMeTAD between 5% and 25% in the fabrication of the cell. Variations of charge ...
First principles study of the ferromagnetism in Ga1-xMnxAs semiconductors

Cosmological mass transport on galactic nuclei and the growth of high-z quasars
(Wiley-VCH Verlag, 2019)
By using cosmological hydrodynamic simulations, we have studied how supernovae (SNe) and active galactic nuclei (AGN) feedback affect the mass transport (MT) process in high-redshift (z ∼ 6) galaxies and what the consequence ...
