PBDTT-DPP, low band-gap semiconducting polymer

High purity and available online for priority dispatch


PBDTT-DPP is a low band-gap polymer with strong photosensitivity in the range of 650-850 nm, with an onset absorption at 858 nm (Eg = 1.45 eV, near infrared absorption). However, it is less sensitive to visible light in the solar spectrum. For this reason, PBDTT-DPP is an ideal candidate for tandem solar cell structures, having achieved device performances of 8.62% (with device structure ITO/ZnO/P3HT:ICBA/PEDOT:PSS/ZnO/PBDTT-DPP:PC71BM/Ag).

Additionally, a single-layer device based on PBDTT-DPP was shown to demonstrate a power conversion efficiency of 6%.[1] PBDTT-DPP also finds application in perovskite solar cells due to its perfect energy level line-ups with perovskites.

Luminosyn™ PBDTT-DPP

Luminosyn™ PBDTT-DPP is now available.

High purity & molecular weight

HPBDTT-DPP is purified by Soxhlet extraction with methanol, hexane and chlorobenzene under an argon atmosphere
