Abstract:
The basic purpose of the thesis is to present studies on dye-sensitized photovoltaic
solar cells based on high band gap mesoporous semiconductor films. Upon excitation
with visible light, dye molecules adsorbed at the surface of the semiconductor could
inject electrons (or holes) into conduction band (or valence band) of the
semiconductor. This effect could be utilized to construct photoelectrochemical cells
that are stable and resistance for photo corrosion.
