Triphenylamine based dyes for dye sensitized solar cells: A review

In recent years a lot of work has been done in the field of dye-sensitized solar cells (DSSC). Dye-sensitized solar cell being a low-cost way for light-energy conversion is an emerging field of research. Triphenylamine based organic dyes (with D–π–A structure) as sensitizer for dye-sensitized solar cells (DSSCs) attain considerable attention because of their structural versatility, low cost and high molar absorption coefficient. In this review discussion is focused on application of TPA based dyes in dye-sensitized solar cells. Special consideration has been paid to study the relationship between molecular structure and DSSC performance. This field seen exciting progress and light to power conversion efficiencies exceed to 11%. Photovoltaic performance of DSSCs sensitized by TPA based dyes is compared and comprehensive overview is provided.
