Exploring the role of spin-triplets and trap states in photovoltaic processes of perovskite solar cells

Revealing the role of spin-triplets and trap states in the recombination and dissociation processes in PSCs.

SOME MASS RELATIONS IN CHARMONIUM

Regge trajectories and hyperfine splitting relations among spin-singlets and spin-triplets in charmonium spectrum were studied. Some interesting conclusions were obtained from the combination of these relations. Especially, the newly observed X(3872) and the old ψ(3836) were analyzed.

Investigation of the Spin-Hamiltonian Parameters and the Local Structure of Ni2+ Ions in CsMgX3 (X = Cl, Br, I) Crystals

Taking into account spin-spin (SS), spin-other-orbit (SOO), and orbit-orbit (OO) interactions in addition to general spin-orbit (SO) interactions, the local structures of Ni2+ in CsMgX3 (X = Cl, Br, I) are theoretically investigated by using the complete diagonalization method (CDM). On this basis, it is found that the local angles, at the Ni2+ centres are larger than those, at the hosts. The contributions to the spin-Hamiltonian parameters from spin triplets and slight magnetic interactions are discussed.
