Polymer Solar Cells Fabricated with Printed Transparent Electrode and Active Layers 

Abstract

Polymer solar cells (PSCs) have advantages of light-weight, mechanical flexibility and high efficiency, and are compatible with low-cost solution-processed technology. Fabrication of high-performance PSCs with potential scalable coating and non-halogenated solvent processing is a necessity. In this talk, we will report our achievement on printed AgNWs-based transparent electrode and morphological manipulation of printed active layer for the printed PSCs. We used non-halogenated solvents combining with high-temperature blade-coating to prepare the PM6:Y6 blend layer. High-temperature blade-coating and non-halogenated o-XY:DMN solvent successfully suppress the excessive aggregation of Y6 and enhance crystallinity of PM6 and Y6 by regulating dynamic process of the active layer formation. We will also report a kind of AgNWs:metal oxide composite transparent conducting film prepared with blade-coating method. The printed flexible PSCs employing the AgNWs:metal oxide composite transparent electrode were fabricated.
