Electrochemical Synthesis of Transition Metal Oxides and Polymer Layers for OPV Fabrication

This paper reports a new method for organic photovoltaic (OPV) fabrication by using the electrochemical synthesis of different transition metal oxides (MoO
₃
, WO
₃
, ZnO, TiO
₂
,V
₂
O
₅
) and polymers (PEDOT:PSS, P 3HT). Especially two materials are presented: MoO
₃
and PEDOT:PSS. The integration of this procedure in a roll-to-roll (R2R) process enables the production of a low-cost OPV with high efficiencies.
