Abstract:
1. A method for manufacturing constituent layers of polymer solar cells by roll to roll coating comprising steps of: unwinding a soft substrate, said soft substrate having a cathode layer disposed thereon; slot-die coating a material of an electron transferring layer including zinc oxide and polyethylenimine ethoxylated (PEIE) on said cathode layer to form the electron transferring layer thereon by spreading PEIE evenly in a ZnO structure; sintering said electron transferring layer on said cathode layer; slot-die coating an active layer on said electron transferring layer and baking said active layer concurrently with a baking temperature ranged from 90 to 150° C., a material of said active layer being made by mixing O-xylene as a solvent; and rewinding said soft substrate.
