Flexible and transparent electrodes
have great potential for photon
transmission and charge-carrier collection for next generation electronics
compared to rigid electronics with indium tin oxide (ITO)-coated glass
substrates. This study describes a comprehensive study of the electrical,
morphological, optical, structural, and mechanical properties of poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)
(PEDOT:PSS) films treated by methanol and methanesulfonic acid (MSA),
which are coated on hydrophobic flexible plastic substrates. Such
a film coated on hydrophobic plastic substrates exhibits a high conductivity
up to 3560 S cm<sup>–1</sup> and a good mechanical flexibility.
Moreover, the use of the films to fabricate bendable ITO-free organic
solar cells (OSCs) integrated on plastic substrates was presented.
The bendable devices based on P3HT:PCBM not only exhibit a high power
conversion efficiency (PCE) up to 3.92%, which is comparable to 4.30%
of the rigid devices with ITO-coated glass substrates, but also keep
about 80% in PCE of the initial value after 100 time bending with
a bending radius of 14 mm in the ambient atmosphere. This work provides
a novel route to dramatically improve the conductivity of PEDOT:PSS
electrodes, as well as the mechanical flexibility of highly efficient
organic electronics with the flexible electrodes.
