Carbon nanotubes as integrative materials for organic photovoltaic devices

In this Highlight article we conduct a critical evaluation of recent advances in the use of carbon nanotubes (CNT) for photocurrent generation. In particular, two strategies have been described. On one hand, CNT serve as photoactive material in photovoltaic devices. Alternatively, CNT are implemented as semitransparent conducting material in the construction of electrodes. Hereby, the following incentives are considered: flexible, transparent, more efficient, and large area organic photovoltaic devices.
