Abstract

Abstract: The use of polyaniline (PANI) and carbon nanotubes (CNTs) as photovoltaic materials has been presented in this paper. The promising properties of PANI and CNTs have encouraged utilizing them in photovoltaic devices and studying their performance. The photovoltaic performance of PANI has been studied with and without CNTs. We found that there is a considerable increase in the short circuit current density from 3.49 to 8.86 mA cm −2 with the use of CNTs in the device and also an increase in power conversion efficiency. The incorporation of CNTs film had led to an efficient transport of photo-generated holes to the anode and suppressed the recombination of free charges generated, thus increasing the efficiency of the device. The performance of the device shows that the PANI and CNTs can be effectively utilized as photovoltaic materials in a photovoltaic cell.
