Spectral signatures of a negative polaron in a doped polymer semiconductor: Energy levels and hubbard U interactions
D. Lungwitz et al. | J. Phys. Chem. Lett. 14 (2023)
The modern picture of negative charge carriers on conjugated polymers invokes the formation of a singly occupied (spin-up/spin-down) level within the polymer gap and a corresponding unoccupied level above the polymer conduction band edge. The energy splitting between these sublevels is related to...

Effect of ground state charge transfer and photoinduced charge separation on the energy level alignment at metal halide perovskite/organic charge transport layer interfaces
L. Frohloff et al. | Appl. Phys. A 129 (2023)
One of the most promising routes for the future fabrication of solution-processable high-performance solar cells is to employ metal halide perovskites as photoactive material combined with organic semiconductors as charge extraction layers. An essential requirement to obtain high device performance...

Defect-dependent optoelectronic properties at a molecular p-dopant / monolayer WS2 interface
J. Ma et al. | Phys. Status Solidi A (2023)
Photoemission and optical absorption experiments indicate that native n-type defects of monolayer WS2 lead to interfacial negatively charged molecular acceptors, which support interlayer charge-transfer excitons.
