Organic Conductive Materials
Organic Semiconductive Polymer: Verazol® HT Series (P3HT)

The Verazol HT series adopts organic semiconductor P3HT (poly (3-hexylthiophene)) with increased molecular weight control based on Soken's unique polymerization technology. The series features low cost due to an efficient manufacturing process, in addition to molecular weight control and a high degree of regioregularity.
Verazol® HT Series Products


All grades feature regioregularity of 97% or higher. In addition to the standard Mw 40 to 70 K and Mw 90 to 130 K, an extra high molecular weight grade of Mw 400 to 700K is available thanks to the increased control over molecular weight.
Grade | Mw | Mw/Mn | Regio-regularity |
---|---|---|---|
Verazol® HT-005 | 40~70K | 1.5~2.5 | ≧97% |
Verazol® HT-010 | 90~130K | 1.5~3.0 | ≧98% |
Verazol® HT-030 | 400~700K | 2.0~3.5 | ≧98% |
Applications
Applications include organic photovoltaics (OPV) and organic field-effective transistors (OFET). For OPV applications, in particular, structural control of bulk heterojunction layers using different grades is expected.


Organic photovoltaics are thin and lightweight, drawing considerable attention as a next-generation solar cell to replace the existing inorganic types.
Flexible solar cell using Soken's semiconductor


Organic transistors can be manufactured at low temperatures using printing techniques, and are receiving well-deserved attention as next-generation transistors. They are expected to be used in devices in ways that are difficult to achieve with existing inorganic transistors.
Applications: IC tags, sensors, organic EL devices, etc.
