comparable to layers fabricated by conventional methods like slot die or spray coating [23]. Diffuse transmission measurements also show that inkjet printed AgNW meshes have a very low haze of only 2.3%, enabling a clear view through semitransparent devices like organic light emitting diodes (OLEDs) or solar cells in which they can be used. Besides this, inkjet printing of silver nanowires does not introduce visually obstructive patterns like silver grids into the cells. These facts combined with the freedom of shape and easy layout change enables the OPV technology to enter highly customized markets like facade integration or automotive applications.
In order to demonstrate the potential of ink jet printed AgNW electrodes in the field of printed electronics, they were applied as cathode and anode in a fully inkjet printed solar cell stack. The resulting PCE of 4.3% is the highest efficiency for fully inkjet printed OPV cells reported so far.
