Relaxation is the key to longer life: suppressed degradation of P3HT films on conductive substrates

Abstract

Here we show the dependence of the degree of degradation of poly-3-hexylthiophene (P3HT) films on the conductivity of the supporting substrate. P3HT is widely used for organic solar cells and electronic devices because it allows simple, low cost fabrication and has potential for the fabrication of flexible devices. However, P3HT is known to have a relatively low photostability, and investigating the photodegradation mechanism is an active research field. We find that P3HT films on conductive substrates show significantly retarded degradation and retain their chemical and morphological features when compared to similar films on glass substrates. This ‘substrate effect’ in retarding the degradation of P3HT films is evident even upon prolonged exposure to air for up to five months.
