FR7-7-PTD is a p-type semiconductor material developed by the Heeger Lab at the University of California, Santa Barbara. It is composed of a blend of 7 parts of PbSe, 7 parts of PbTe, and 2 parts of PbS. FR7-7-PTD has a bandgap of approximately 2.3 eV, making it suitable for use as a light-absorbing component in photovoltaic cells. In addition to its increasing use in photovoltaics, FR7-7-PTD has also been used for infrared sensing applications. The Heeger Lab's research activities are focused on the synthesis, characterization and applications of novel materials for optoelectronic, photovoltaic, and infrared sensing applications.
