TL;DR: In this article, a hybrid ternary model system based on a poly(3-hexylthiophene) (P3HT)/zinc phthalocyanine (ZnPc)/ZnO interface was used to study heterojunction interfaces of hybrid polymer solar cells, with the aim to better understand and precisely predict their photovoltaic properties.
Journal ArticleDOI
Structure and passivation effects of mono- and dihydrogen complexes in GaAsyN(1-y) alloys.
TL;DR: In GaAsyN(1-y), the presence of a few percent of N induces a large reduction of the GaAs band gap that vanishes upon hydrogenation, and a model is proposed that clarifies the passivation mechanism of nitrogen by H.

Zinc Oxide-Zinc Phthalocyanine interface for Hybrid Solar Cells
Giuseppe Mattioli,Claudio Melis,Giuliano Malloci,Francesco Filippone,Paola Alippi,Paolo Giannozzi,Paolo Giannozzi,Alessandro Mattoni,Aldo Amore Bonapasta +8 more
TL;DR: In this article, the structural, electronic, and optical properties of a hybrid interface formed by zinc phthalocyanine (ZnPc) molecules adsorbed on the (1010) zinc oxide surface have been investigated by using ab initio and model potential theoretical methods.
Journal ArticleDOI
Theory of the metal-nonmagnetic Mott-Jahn-Teller insulator transition in A 4 C 60
TL;DR: In this paper, the authors studied the insulating properties of the Mott-Jahn-Teller (MJT) state in a nonmagnetic state, where conduction between molecules is blocked by on-site Coulomb repulsion, magnetism is suppressed by the intramolecular Jahn Teller effect, and important excitations (such as optical and spin gap) should be essentially intra-olecular.
