Polythiophenes photovoltaics based

The photovoltaic properties of PPV and PPV based soluble polymers have been quantitatively confirmed also for polythiophenes. The IN characteristics of ITO/ P30T/Au [60] and of ITO/P3HT/Au [61] diodes showed excellent rectification behavior and a high photosensitivity under reversed bias.

During the last decade, there have been countless studies devoted to the synthesis of different thiophene-based polymers and oligomers for photovoltaic applications and various photoconversion efficiencies ranging from 0.1 to 5 % have been reported for devices based on such materials. We have chosen some references that cover a small part of the literature on polythiophene-based [40-54] and oligothiophene-based [55-60] devices with relatively successful photovoltaic performance. Figure 18.3 shows the molecular structures of some of the most successful materials, and their optical bandgaps and PCE are given in Table 18.1.
