Usage

Classification

Polycarbazoles, Heterocyclic five-membered ring, Organic semiconducting materials, Low band gap polymers, Organic photovoltaics, Polymer solar cells, OFETs and Perovskite solar cells.

Applications

PCDTBT for high performance organic photovoltaics and air stable OFETs and perovskite solar cells. PCDTBT is one of the next generation donor materials developed for organic photovoltaics to produce better efficiencies and lifetimes. The key properties of PCDTBT result from the lower HOMO/LUMO levels which lead to advantages over standard organic photovoltaic materials of increased open circuit voltage, longer wavelength absorption and improved stability under ambient conditions. The lower lying HOMO level of PCDTBT makes it much more stable under ambient conditions and therefore an ideal candidate to use with large area deposition methods such as ink-jet printing, spray coating and blade coating. However, for these deposition techniques, uniform, aggregate free coatings are essential and so lower molecular weights are often desirable. Power conversion efficiencies of up to 6.7% have been achieved using PCDTBT (M137) in a standard reference architecture using PEDOT:PSS as a hole interface and calcium/aluminium as an electron interface. By using advanced interface materials and antireflection coatings PCDTBT has also achieved up to 7.2% in the literature.

Description

PCDTBT is one of the next generation donor materials developed for organic photovoltaics to produce better efficiencies and lifetimes. The key properties of PCDTBT result from the lower HOMO/LUMO levels which lead to advantages over standard organic photovoltaic materials of increased open circuit voltage, longer wavelength absorption and improved stability under ambient conditions.

Uses

PCDTBT blend with PCBM as a nanocomposite can be used as a donor/acceptor material for the fabrication of photovoltaic solar cells and photovoltaic inks. It may also be used as an active layer that can be used in the development of organic field effect transistors (OFETs) for the parts per million (ppm) level detection of NO2 gas.

General Description

Soluble in THF, chloroform, chlorobenzene, dichlorobenzene, and 1,2,3-trichlorobenzene
