Structural and electrical studies on PVDF: PANI composite thin films and their application as buffer layer on hybrid solar cells
Hybrid (organic-inorganic) solar cells were fabricated and tested using buffer layer of polyaniline (PANI)-poly(vinylidene difluoride) (PVDF) composites. The effect of PANI:PVDF composite on the performance of the solar cells was explored and the cells were characterized by current voltage (I-V) measurements under a solar simulator generating AM1.5 light (1000W/m(2)) irradiance. It was found that solar cells containing ITO/PANI:PVDF photo-anode are likely to improve photocurrent and power conversion efficiency in a way superior to that containing only ITO as photo-anode. Furthermore, PANI:PVDF composite enhanced the hole extraction at photo-anode/photo-active layer interface via the high electrical conductivity of PANI and the ferroelectricity of PVDF.
