Βελτιστοποίηση συνθηκών για πιεζοηλεκτρική εκτύπωση πλέγματος αργυρού και εφαρμογή του για κάτω ηλεκτρόδιο σε οργανικές φωτοβολταϊκές διαλέξεις

Abstract

Organic photovoltaics are attracting great scientific interest due to the low weight, flexibility and possibility of low cost roll-to-roll production.In this Thesis, basic working principles have been analyzed as well as main deposition techniques used in MEP laboratories.Inkjet printed silver solution was deposited on glass substrates in order to further reduce organic photovoltaic's fabrication cost.Optimum conditions and parameters were found after sedulous investigation for layer as well for single line deposition.On top of the latter an interfacial layer of PEDOT:PSS was Doctor Bladed and then a mixture of P3HT:PCBM was deposited above that.Aluminum was thermally evaporated in order to form metal cathode.A Power Conversion Efficiency of 1.96% was obtained with this device structure and parts of the results were submitted for publication to referred international journal.
