Abstract
PEDOT:PSS based silicon organic heterojunction solar cells are fabricated with a highest efficiency of 8.92%. It is found that a good quality, ultra-thin oxide layer (~1–2 nm) over the substrate increases adhesion of polymer with the silicon substrate which has positive effect on fill factor of the device. This ultra-thin oxide layer led to an absolute increase of 1.86% in power conversion efficiency of the device. This layer has marginal negative impact on open-circuit voltage of the device.
