Research activities in the field of diketopyrrolopyrrole (DPP)-based polymers are reviewed. Synthetic pathways to monomers and polymers, and the characteristic properties of the polymers are described. Potential applications in the field of organic electronic materials such as light emitting diodes, organic solar cells and organic field effect transistors are discussed.

Due to their high transparency, electrodes fabricated from conductive polymers are often implemented in semitransparent organic solar cells. Opaque cells usually employ metal back with reflectivity for best photon confinement the light-harvesting layer. Herein, a bilayer electrode comprising and nanofoamed poly(methyl methacrylate) (PMMA) is investigated, latter of which creates diffuse reflect...

The tandem structure provides a practical way to realize high-efficiency organic solar cells (OSCs). It overcomes several bottlenecks in single-junction OSCs such as thermalization loss, transmission and inefficient light absorption. In OSCs, the interconnecting layer (ICL) electrically connects two subcells it plays critical role determining device performance reproducibility. this review pape...
