The BCL Method for DSSC: Basis and Applications

Autor: Mauricio Barrera, Irma Crivelli, Barbara Loeb

Publikováno v: Applied Sciences, Vol 12, Iss 5, p 2358 (2022)

In this work, a comprehensive view of the route that led to the construction of a theoretical approach to the functioning of DSSC is presented. The model was developed based on the theoretical interpretation of experimental results obtained along the

The role of lithium cations on the photochemistry of ruthenium complexes in dye-sensitized solar cells: A TDDFT study with the BCL model

Autor: Shane Ardo, Irma Crivelli, Gerald J. Meyer, Bárbara Loeb, Mauricio Barrera

Publikováno v: Journal of Photochemistry and Photobiology A: Chemistry. 364:510-515

Lithium cations have been shown to impart an electrostatic Stark effect on molecules bound to mesoporous metal oxides commonly used in dye-sensitized solar cells. Herein, using the Barrera-Crivelli-Loeb theoretical model accompanied by Time Dependent

Nonlinear optical response of octupolar Zn(II) complexes incorporating highly aromatic polypyridinic ligands: Insights into the role of the metal center

Autor: Isabelle Ledoux-Rak, Irma Crivelli, Luis Sanhueza, Diego Cortés-Arriagada, Bárbara Loeb

Publikováno v: Synthetic Metals. 234:9-17

In this work, the linear and nonlinear optical properties of a series of octupolar Zn(II) complexes with highly aromatic polypyridine ligands are investigated. The effect of the metal center on the spectroscopic properties of octupolar Zn (II) comple

Publikováno v: Polyhedron. 85:511-518

In this work we report the preparation of six new donor–metal–acceptor (D–M–A) type complexes of ruthenium(II) with the highly absorbing “chromophoric” ligand 4,4′-bis(2-(4-methoxyphenyl)styryl)-2,2′-bipyridine, (L-OCH3, donor moiety)

On the performance of ruthenium dyes in dye sensitized solar cells: a free cluster approach based on theoretical indexes

Autor: Mauricio Barrera, Irma Crivelli, Bárbara Loeb

Publikováno v: Journal of Molecular Modeling. 22

The performance of ruthenium dye sensitized solar cells (DSSC) with different types of ligand was studied by means of a theoretical model where the ruthenium complex is bound to two [Ti(OH)3](+) units, instead of the more usual cluster TiO2 model. El
