Abstract
The organic solar cells have experienced a great improvement in efficiencies over the past 5 years, mostly due to the development of new acceptor materials including the landmark acceptor, Y6, and a series of Y6-based derivative acceptors. In this work, we study a broad range of Y6-type acceptors using transient optical spectroscopy techniques and reveal the precise relationships between molecular structure, film morphology and ultrafast excited-state dynamics in these materials, which are closely correlated to the corresponding blend device performance.
