Abstract

Solar cell heterostructures based on PEDOT:PSS/Si heterojunction with a flat and microrelief interfaces of pyramidal and inverted pyramids type, unmodified and chemically doped PEDOT:PSS films have been fabricated. The maximum efficiency of 6.14% was obtained for solar cell heterostructures with a pyramidal type interface and doped PEDOT:PSS film, which is five times higher than for structure with a flat interface. It shown that an increase in the efficiency is occurred both due to decrease in optical losses from textured Si interface and improvement of electrical parameters of the polymer layer due to chemical doping with DMSO.
