Abstract

Organic electronic devices, compositions, and methods are disclosed that employ electrically conductive nanowires and conducting materials such as conjugated polymers such as sulfonated regioregular polythiophenes which provide high device performance such as good solar cell efficiency. Devices requiring transparent conductors that are resilient to physical stresses can be fabricated, with reduced corrosion problems.
