Polymer light-emitting diodes (PLEDs) and organic photovoltaics (OPVs) are considered as next generation electronics due to the low-cost, flexibility, and lightweight features. However, there are challenges such as large-area processing technologies, film coating quality, and long-term stability toward scalable and low-cost polymer electronics. This chapter deals with the various scalable processing methods and evaluates the coating performance as well as electrical performances in polymer electronics fabricated by the solution processes. Special attention on coating instability is elaborated in the context of important material components in PLEDs and OPVs. Proper coating techniques can be chosen by considering the thickness requirement of each functional layer with good reproducibility. Additionally, we will evaluate mechanical/optical characteristics of the polymer anode for ITO-free electrodes; and introduce the metal mesh in combination with conductive polymers as the ITO-free transparent electrode for large area applications.
