Electroabsorption spectroscopy of quasi-one-dimensional organic molecular crystals
… thin films to clarify the involvement of the charge-transfer exciton in the lowest excited state. By a self-built experimental setup, two kinds of electroabsorption measurements, called "perpendicular" and "parallel" measurements, were conducted at room temperature in …

Spectroscopic Studies of Charge Dynamics in Non-Fullerene Organic Solar Cells
… achieved. Furthermore, they have shown efficient charge separation with negligible energy loss, overcoming one of the crucial limitations of fullerene based OSC. Here, we present a study on the charge generation, separation, and recombination dynamics of non-fullerene solar cells. We investigate …

Electronic excited states in quasi- one- dimensional organic solids with strong coupling of Frenkel and charge-transfer excitons
… Thus, the concept of the small radius exciton theory in linear molecular chains was adopted to examine the excitonic states. The excited states are composed of molecular excitations and nearest neighbor charge transfer (CT) excitations. We analyzed the structure and properties of the …

The role of spatial size and orientation of electronic wavefunction in exciton dissociation at van der Waals interfaces
… are generated directly by the light absorption, excitons, Coulombic bound electron-hole pairs, are created upon light absorption in OPV materials. The performance of OPVs depends on how effective the bound charge transfer (CT) exciton, an exciton with its electron and hole spatially separated by …
