• A layer of titania semi-spherical shell is assembled onto the titania nano-crystalline film.
• The shell performs as a concave mirror.
• Unlike random scattering centers, the unique structure reflects full band incident light back into the photo-anode.
• Conversion efficiency is enhanced by the semi-spherical shell.
A layer of titania semi-spherical shell is assembled onto the titania nano-crystalline film to serve as photo-anode in dye-sensitized solar cells. The shell performs as a concave mirror. Unlike random scattering centers, the unique structure reflects full band of the incident light back to the titania nano-crystalline film in a convergent way. As a result, conversion efficiency is drastically enhanced by the semi-spherical shell coating with a maxima ratio of over forty-seven percent on cells with an effective area of 100 mm2.
