Abstract

Organic solar cells have been intensively developed worldwide during the last two decades. After breaking the psychological barrier of 10% in power conversion efficiency (PCE), which was accomplished in 2011 by Mitsubishi Chemical, many academic and industry research groups generated tens of promising material combinations delivering PCEs>10%-11%. In spite of impressive efficiencies reached for small-area devices, it is still a big challenge to push this technology from labs to industry. The list of main obstacles includes low stability of vast majority of organic materials, limiting device lifetime; problematic upscaling related to the low reliability of large-area processing thin composite films with crystalline domains; and, finally, high cost of raw organic materials. To solve these challenges, principally new materials are urgently needed. In this chapter, we summarize the main principles of designing efficient electron donor conjugated polymers, discuss the relationships between the molecular structures and properties of the designed nanomaterials with their performance in real devices, and outline the material design strategies, which are expected to lead the further progress in the field.
