Fabrication of organic solar cells based on a blend of poly (3-octylthiophene-2, 5-diyl) and fullerene derivative using inkjet printing technique

This paper reports the fabrication of organic solar cells using inkjet printing technique. The devices consist of an active layer sandwiched between ITO bottom electrode and aluminum as top electrode. The active layer is made of a blend of a fullerene derivative [6,6]-phenyl C61-butyric acid 3-ethylthiophene ester as acceptor and poly (3-octylthiophene-2, 5- diyl) (P3OT) as the donor. The ink of active layer was prepared with variation of donor...
