Highly Efficient Flexible Hybrid Photovoltaic Cells Based on Low-Band-Gap Conjugated Polymers Sensitized by Nanoparticle-Grafted Carbon

Abstract

During the entire project period, significant progress was made on the design, modeling, synthesis, and characterization of several series functional and processable electro-active conjugated polymers with evolving frontier orbital energy levels and energy gaps that are very attractive for optoelectronic applications at VIS-NIR radiation energy ranges. Details of these new functional polymer developments are described. In addition, quantum dot grafted carbon nanotubes for potential optoelectronic applications were studied. All materials developed were fabricated into devices and their performance characteristics were evaluated. These include low-band-gap conjugated polymers such as 55-C12-PTV, SFPTV and P(C6OTV-SFTV), as well as the (-DBAB-)n block copolymer systems, and quantum dot-grafted carbon nanotubes.
