Abstract
We report an in-depth investigation of an inkjet-printed silver (Ag) nanoparticle grid combined
with poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) of different
conductivities as an alternative to an indium tin oxide (ITO)-based transparent anode for
organic solar cell applications. The reported measurements revealed higher transparency of the
inkjet-printed Ag nanoparticle-based grid when compared to different thicknesses of ITO on
glass substrates. Based on the proposed current collecting grid, a record power conversion
efficiency of 2% is achieved for ITO-free organic solar cells
