Description

(5Z,5'Z)-5,5'-((7,7'-(4,4,9,9-tetraoctyl-4,9-dihydro-s-indaceno[1,2-b:5,6-b']dithiophene-2,7-diyl)bis(benzo[c][1,2,5]thiadiazole-7,4-diyl))bis(methanylylidene))bis(3-ethyl-2-thioxothiazolidin-4-one) is a high-performance, non-fullerene electron acceptor (NFA) organic semiconductor material. It is engineered to deliver exceptional power conversion efficiency and stability in advanced organic photovoltaic (OPV) devices. This compound is critical for researchers and manufacturers developing next-generation solar cells, organic photodetectors, and other optoelectronic applications.

Application

• Organic Photovoltaic (OPV) Cells: As a key electron-accepting component in bulk heterojunction active layers for high-efficiency solar energy conversion.
• Organic Photodetectors (OPDs): Used in light-sensing devices for imaging, communication, and biomedical sensing due to its tunable absorption properties.
• Organic Field-Effect Transistors (OFETs): Employed in the n-type semiconductor layer for developing flexible and printed electronics.
• Perovskite Solar Cells: Investigated as an electron transport layer (ETL) or interfacial material to enhance device performance and longevity.
• Academic & Industrial R&D: Serves as a reference material for synthesizing novel conjugated polymers and small molecules for optoelectronics.
• Printed Electronics: Suitable for solution-processed fabrication techniques like spin-coating and inkjet printing for large-area, flexible devices.
