A comprehensive experimental study of five fundamental phenothiazine geometries increasing the diversity of the phenothiazine dye class for dye-sensitized solar cells
Buene, Audun Formo; Hagfeldt, Anders; Hoff, Bård Helge (Journal article; Peer reviewed, 2019)Phenothiazine is a versatile scaffold frequently used in both pharmaceutical and photovoltaic applications. Still, the structural diversity within the class of phenothiazine sensitizers for dye-sensitized solar cells is ... -
Auxiliary donors for phenothiazine sensitizers for dye-sensitized solar cells – how important are they really?
Buene, Audun Formo; Ose, Eline Ekornhol; Zakariassen, Ane Garborg; Hagfeldt, Anders; Hoff, Bård Helge (Journal article; Peer reviewed, 2019)Auxiliary donors are common design motifs for phenothiazine sensitizers for dye-sensitized solar cells. Despite this, there are only a few reports on their overall contribution to the photon-to-electron conversion efficiency. ... -
Effect of furan π-spacer and triethylene oxide methyl ether substituents on performance of phenothiazine sensitizers in dye-sensitized solar cells
Buene, Audun Formo; Boholm, Nanna; Hagfeldt, Anders; Hoff, Bård Helge (Journal article; Peer reviewed, 2019)Conjugated π-spacers are used to improve the light harvesting properties of sensitizers for dye-sensitized solar cells. In several recent works, furan has outperformed other popular π-spacers such as thiophene and phenyl. ... -
First Report of Chenodeoxycholic Acid–Substituted Dyes Improving the Dye Monolayer Quality in Dye-Sensitized Solar Cells
Buene, Audun Formo; Almenningen, David Moe; Hagfeldt, Anders; Gautun, Odd Reidar; Hoff, Bård Helge (Journal article, 2020)Chenodeoxycholic acid (CDCA) is the most used anti-aggregation additive in dye-sensitized solar cells since its introduction to the field in 1993. However, effective suppression of dye aggregation comes at the cost of ...
