Host Organization

Project goals

  • Successfully manufacturing smart fibers through combining 3D printing and thermal drawing techniques.
  • Integrating organic semiconductors into fibers using wet coating methods.
  • Manufacturing high-performance fiber photovoltaic cells.
  • The project will contribute to training 9 students (6 bachelor’s, 2 master’s students, and 1 PhD student), along with 5 scientific publications (3 Q1) and 2 patents.

Project impact

Fibers and fabrics are man-made products that have a large area, are light, and are easy to integrate; Fiber photovoltaics have the potential to create remote power charging stations, wearable power sources, and utilization of excess optical power at home. Further, creating photovoltaic fibers in particular and smart fibers in general can be the potential to transform the processed textile industry into an advanced textile industry with high gray matter content.
