Solution Processed MoO3 Interfacial Layer for Organic Photovoltaics Prepared by a Facile Synthesis Method


An MoO3 film spin-coated from a solution prepared by an extremely facile and cost-effective synthetic method is introduced as an anode buffer layer of bulk-heterojunction polymer photovoltaic devices. The device efficiency using the MoO3 anode buffer layer is comparable to that using a conventional PEDOT:PSS layer without annealing at an elevated temperature.
