Metal-free organic sensitizers with a sterically hindered thiophene unit for efficient dye-sensitized solar cells
Two new organic sensitizers for dye solar cells containing a sterically hindered moiety have been synthesized. The introduction of a 3,4-dibutyl-thiophene ring into D-π-A dyes reduces the sensitizer aggregation and allows the preparation of solar cells wi
