Paper Abstract

Inkjet printing is considered a promising technique for industrial production of Organic Photovoltaic (OPV) devices, especially due to its minimal consumption of materials, the easy modification of the numerical design and because this is a non-contact process. The objective of this study is to make efficient modules at a semi-industrial scale using 128 nozzle heads. In order to maximize the performance and lifetime, an inverted device structure was used consisting of: transparent plastic conductive substrate / N-layer / active layer / P-layer / silver electrode. Formulations and processes were therefore developed for substituting each spin-coated layer with an ink-jet printed layer. For 3.7 cm2 cells power conversion efficiency (PCE) reaches 3.3 % with only N-layer printed, 2.4 % with only active layer printed, 3.0 % with only P-layer printed and 2.9 % with only the silver electrode printed. Three-cell modules of 11 cm2 on 5x5 cm2 substrates were also made. Most PCE reach >2 % for each inkjet printed layer.
