Materials Based on Carbazole for Organic Solar Cells Applications. Theoretical Investigations
The research in new organic π-conjugated molecules with specific properties has become one of the most interesting topics in fields of materials chemistry. These materials are promising for optoelectronic device technology such as solar cells. On the other hand, the use of low band gap materials is a viable method for better harvesting of the solar spectrum and increasing its efficiency. The Co...

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.
متن کاملSynthesis and characterization of π-conjugated copolymers with thieno-imidazole units in the main chain: application for bulk heterojunction polymer solar cells.
In this paper the three new narrow bandgap D–A conjugated copolymers P1, P2 and P3 based on different weak donor fused thiophene-imidazole containing derivatives and the same benzothiadiazole acceptor unit were synthesized by Stille cross-coupling polymerization and characterized by 1H NMR, elemental analysis, GPC, TGA, DSC. These copolymers exhibit intensive absorbance in the range 350–900 nm ...
متن کاملSynthesis of thienoselenadiazole-containing conjugated copolymers and their application in polymer solar cells
INTRODUCTION In recent years, polymer solar cells (PSCs) have attracted great attention due to the energy crisis all over the world. Compared with inorganic solar cells, PSCs have many advantages, such as light weight, solution processability, mechanical flexibility and low cost.1 The stateof-the-art of PSCs are based on a fullerene-derivative acceptor, such as [6,6]-phenyl-C61-butyric acid met...
