PBDT-TBP is a conducting polymer with benzodithiophene (BDT) donor groups and thieno[3,4-c]pyrrole-4,6(5H)-dione acceptor groups. It has π bridges that can be synthesized by palladium (Pd) catalyzed Stille-coupling. These π-conjugations are used to enhance the optical and electrochemical properties of the polymer.

Application

High-Efficiency Organic Solar Cells (OPVs); devices prepared from mixed solvents chlorobenzene/1; 8-diiodooctane
PBDT-TBP is a donor-acceptor polymer which can be used in the fabrication of bulk heterojunction solar cells (BHJ-SCs).

Professor Chen (Nankai University, China) and his team explain the strategies behind their recent record-breaking organic solar cells, reaching a power conversion efficiency of 17.3%.

Inverted Organic Photovoltaic Devices Using Zinc Oxide Nanocomposites as Electron Transporting Layer Materials

Organic photovoltaics (OPVs) represent a low-cost, lightweight, and scalable alternative to conventional solar cells. While significant progress has been made in the development of conventional bulk heterojunction cells, new approaches are required to achieve the performance and stability necessary to enable commercially successful OPVs.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
