Organic dyes incorporating 9,10-dihydrophenanthrene moiety for dye-sensitized solar cells

A series of new dipolar organic dyes containing 9,10-dihydrophenanthrene has been synthesized as sensitizers for the application in dye-sensitized solar cells. These new materials containing less rigid π–linker as sensitizers exhibit good performance with conversion efficiencies ranging from 1.58percent to 6.21percent reaching 11 ～ 83percent of the ruthenium dye N719-based cell under the same condition.

Dihydrophenanthrene-based metal-free dyes for highly efficient cosensitized solar cells

Metal-free dyes (BP-1 to BP-3) containing a 9,10-dihydrophenanthrene unit in the spacer have been synthesized. The dye with the highest cell efficiency, BP-2, was used in combination with SQ2 for cosensitized DSSCs. The cosensitized DSSC in which the ratio of BP-2 and SQ2 is 8:2 (v/v) has a record high efficiency of 8.14% among cosensitized systems using all metal-free sensitizers. Dye distribution along the TiO2 film depth was analyzed by an Auger electron spectroscopy technique.
