Abstract- This paper introduce the surface modification for film dye sensitized solar cells (film DSSCs) using atmospheric pressure microplasma as a damage less surface treatment process. The photo conversion efficiency was improved by about 0.3%-0.6% after O2 or Ar microplasma treatment. Dye adsorption amount owing to the increase of OH bonds and surface defects on TiO2 surface were increased after both microplasma treatments. The effects of the microplasma treatments on DSSSs surface were analyzed by photovoltaic measurements, X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM) analysis.
