Towards anode with low indium content as effective anode in organic solar cells

► The manuscript is dedicated to the realization of anode with low indium content. ► We show that a very thin In2O3 film deposited onto another transparent conductive oxide (TCO = ZnO, SnO2) allows to improve the contact between the TCO and the organic material. ► Optima results are achieved when a thin MoO3 thin film is added to these bilayer structures.
