Impedance spectroscopy on ITO-free polymer solar cells

Abstract

Indium tin oxide (ITO) is the most common transparent anode for polymer solar cells (PSCs). The limited flexibility of ITO, the increasing cost of indium and the patterning of ITO with a lot of chemicals, make this material not desirable for the realization of flexible, low-cost and efficient PSCs. Poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate… (More)
