摘要：
We combine inkjet printed silver grids and reverse nanoimprinting transfer to demonstrate front electrode structures embedded within the substrate for indium tin oxide (ITO) replacement in organic solar cells. The smooth interface between Ag grid and transparent semiconductor polymer PEDOT:PSS improves the topology of the successive layers. In turn, this results in overall good photovoltaic performance including high fill factor and no shunting. By modelling the shadowing and resistive losses as a function of the separation between grid lines, the optimal grid structure is identified, which we then confirm experimentally. Inkjet printed ITO-free solar cells showed slightly higher performance than the ITO based reference. (C) 2014 Elsevier B.V. All rights reserved.
