The bulk-heterojunction blend of an electron donor and an electron acceptor material is the
key component in a solution-processed organic photovoltaic device. In the past decades, a p …

Although fullerenes and their derivatives, such as PCBM, have been the dominant electron-
acceptor materials in organic photovoltaic cells (OPVs), they suffer from some …

Organic photovoltaic cells (OPVs) are a promising cost-effective alternative to silicon-based
solar cells, and possess light-weight, low-cost, and flexibility advantages. Significant …

Perylene imides have been an object of research for 100 years and their derivatives are key
n‐type semiconductors in the field of organic electronics. While perylene diimides have …

Perylene-3, 4, 9, 10-tetracarboxylic acid diimides (perylene diimides, PDIs) have been used
as industrial pigments for many years. More recently, new applications for PDI derivatives …

Perylene-3, 4, 9, 10-tetracarboxylic acid diimides (PDIs) and their derivatives represent one

Energy will be one of the most important factors to influence human society in the 21st
century. 1, 2 Cost, availability, and sustainability of energy have a significant impact on the …

Heterojunction organic photovoltaics have been the subject of intensive academic interest
over the past two decades, and significant commercial efforts have been directed towards …

Porphyrin-based dyes recently have become good candidates for dye-sensitized solar cells
(DSCs). However, the bottleneck is how to further improve their light-harvesting ability. In this …

We systematically investigate at the density functional theory level how changes to the
chemical structure of donor–acceptor copolymers used in a number of organic electronics …
