P3HT is used as an electron Donor to acceptor materials such as PCBM (SOL5061) to make proven benchmarked bulk heterojunction solar cells and organic transistors.



P3HT – SOL4106

CAS: 104934-50-1

P3HT (poly(3-hexylthiophene-2,5-diyl) is a p-type conductive polymer chain that is currently one of the most widely used materials in photovoltaics due to its interesting electronic properties.

One of the most studied applications of P3HT is the development of organic photovoltaic cells with heterojunctions, which are produced in solution because they are light, flexible, and inexpensive to manufacture. These cells are developed using a mixture of (poly(3-hexylthiophene) and phenyl-C61-butyric acid methyl ester (P3HT:PCBM).

We offer three grades with different molecular weights for a variety of research purposes.

Choose between:

Mw = 70-90 kD, low pdi – P3HT RR 90-95% (SOL4106A)

Mw = 50-70 kD, low pdi – P3HT RR 87-92% (SOL4106B)

Mw = 30-50 kD, low pdi – P3HT RR-87-92% (SOL4106C)
