High-Performance Semiconductor Polymers Based on Diketopyrrolopyrrole and Thienothiophene

The development of high-performance conjugated organic molecules and polymers has received widespread attention in industrial and academic research.

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.

Progress for High Performance Tandem Organic Solar Cells

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%.
