| 3,3-b]dithiophene]{3-fluoro-2[(2-ethylhexyl)carbonyl]thieno[3,4-b]thiophenediyl}) Usage And Synthesis |
| Classification | Organic semiconducting materials, Low band gap polymers, Organic photovoltaics, Polymer solar cells, Tandem solar cells, Perovskite solar cells.
| | Applications | 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%.
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.
