Research Abstract	In this work, we have investigated the inverted type organic solar cells with composite thin films of polymer materials and carbon nanotubes. It was found that the inverted type polymer solar cells are improved by introducing hole transport layer of PEDOT:PSS and carbon nanotubes with additional cap layer. We have also investigated that dispersion of carbon nanotubes in the PEDOT:PSS and carbon nanotube composite thin films by charge contrast imaging using SEM. We found that incident current to the samples is an important parameter to obtain charge contrast images of the composite films. The present results indicate that charge contrast imaging using SEM is a useful way to characterize homogeneity in composite thin films of PEDOT:PSS and carbon nanotubes.
