Nanocellulose �Bacterial cellulose films and electrospun fibers ◦ Derived from abundant and renewable resources, non-toxic �Thin films �Highly porous ◦ Absorbing sponge

Solar Cells with Nanocellulose � Method to deposite electrolyte in DSC ◦ Nanocellulose absorbs the electrolyte � No electrolyte pumping needed → no uneven distribution of electrolyte components ◦ Molecular filtering effect � No filling holes → simplifies the sealing of the cell Miettunen, K. et. al.
