Solar cells are an important alternative for generating clean and sustainable electricity. Cellulose acetate is a low-cost cellulose derivative that possesses, among other characteristics, stability, a surface rich in functional groups, uniformity, and the possibility of producing flexible, conformable and fine devices. In the present project, it is intended to use cellulose acetate, zinc oxide (ZnO), combined or not with nanocrystalline cellulose (CNC), in order to obtain solar cell components from the electrospinning technique. Photovoltaic properties can be checked using nanoparticles, which transfer electrons easily and are transparent. In this context, biobased materials will be obtained from cellulose acetate, CNC, and ZnO and their photovoltaic properties will be evaluated. The proposal herein is part of the doctoral project developed by the student who is applying for this scholarship. (AU)
