The involvement of charge-transfer (CT) states in the photogeneration and recombination of
charge carriers has been an important focus of study within the organic photovoltaic …

A blend of a low‐optical‐gap diketopyrrolopyrrole polymer and a fullerene derivative, with
near‐zero driving force for electron transfer, is investigated. Using femtosecond transient …

Charge separation (CS) is a central process in the working of organic solar cells (OSC).
Despite the strong electron–hole (e–h) Coulombic attraction at the donor–acceptor (D–A) …

Charge carrier photogeneration is studied in photovoltaic blends of the conjugated polymer
PTB7 with the electron acceptor PC71BM at low excitation densities using broadband …

In this work, the electric field dependence of the exciton quenching efficiency at the
