Spectroscopic Studies of Organic Photovoltaic Non-Fullerene Acceptors
… a class of functional organic materials called ‘non-fullerene acceptors’ (NFAs). They have become well-established as a component in the bulk heterojunction active layer of organic photovoltaic (OPV) cells, and are credited with facilitating a rapid increase in the power conversion efficiencies …

Singlet Fission Organic Solar Cell with Long-Wavelength Absorption Using Non-fullerene Acceptors
… fission material, and Y6, a long-wavelength non-fullerene acceptor material. We characterized their current-voltage characteristics, internal and external quantum efficiency, and change in photocurrent under a magnetic field. We demonstrated successful triplet exciton dissociation at the …

Tailoring functional Π-conjugated polymers and molecules for organic photovoltaic applications
… which assembles into highly ordered domains. Non-covalent interactions such as π-π interactions, hydrogen bond, dipole-dipole interactions, and steric effect determine the spontaneous self-organization processes. However, this self-assembly process, both in solution and during film formation, …

Ultrafast Spectroscopic Studies of Solution-Processing Organic Photovoltaic Materials and Devices
… the ‘classical’ broadly studied polythiophene-fullerene blends to the high-performance OSC devices based on non-fullerene acceptors (NFAs). Firstly, the rate of exciton dissociation is studied in state-of-the-art organic blends with NFAs. The charge generation is found to be slow (ps), in sharp …

Spectroscopic Studies of Charge Dynamics in Non-Fullerene Organic Solar Cells
… has been made recently by the development of non-fullerene electron acceptor materials. They benefit from good tunablity of energy levels as well as greater thermal and photochemical stability, and remarkable power conversion efficiencies of up to 16.5 % have been achieved. Furthermore, they …
