This book reports on the design, synthesis and characterization of new small molecule electron acceptors for polymer solar cells. Starting with a detailed introduction to the science behind polymer solar cells, the author then goes on to review the challenges and advances made in developing non-fullerene acceptors so far. In the main body of the book, the author describes the design principles and synthetic strategy for a new family of acceptors, including detailed synthetic procedures and molecular modeling data used to predict physical properties. An indepth characterization of the photovoltaic performance, with transient absorption spectroscopy (TAS), photo-induced charge extraction, and grazing incidence X-ray diffraction (GIXRD) is also included, and the author uses this data to relate material properties and device performance. This book provides a useful overview for researchers beginning a project in this or related areas.

Sarah Holliday obtained her undergraduate degree in Chemistry at the University of Edinburgh, UK before moving to Imperial College London to pursue her PhD studies under the supervision of Prof. Iain McCulloch and Dr. Mathieu Turbiez (BASF). Her work on non-fullerene acceptors is considered an important contribution to the field of organic photovoltaics. She is currently a postdoc at the University of Washington, USA.
