Cellulose-based organic solar cells via spray deposition

In this project, we use spray deposition to fabricate cellulose-based, flexible organic solar cells. We use TEMPO-cellulose nanofibrils (TEMPO-CNF) as sustainable substrate material, flexible silver- or copper-nanowires (AgNW-/CuNW) as electrode material, conductive poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) as electron blocking layer, and a mixture of poly(3 hexylthiophene) (P3HT) and [6,6]-phenyl C61 butyric acid methylester (PCBM) as …

Characterisation and effects of micro- and nanoscale components and their impact on efficiency of chemical additives

The project’s focus is on developing a methodology that will provide new knowledge and processcontrol capabilities concerning nano- and microscale fibrillar wood-pulp material in thepapermaking process.

Conducting polymers-modified wood composites

In this project, we used different conducting polymers to impregnate the wood. Our goal is to create a pathway for studying the nano/microscopic structure of the conductive wood and the interactions between the wood components and the conducting polymer matrix. . In detail, we mainly focus on the difference of crystallinity and the orientation of …
