Toward Sustainable, Colorless, and Transparent Photovoltaics: State of the Art and Perspectives for the Development of Selective Near?Infrared Dye?Sensitized Solar Cells

Dye-sensitized solar cell (DSSC) is one of the promising photovoltaic (PV) technologies for applications requiring high aesthetic features combined with energy production such as building integration PV (BIPV). In this context, DSSCs have ability to be wavelength selective, thanks development new sensitizers by molecular engineering. The long history dye research has afforded technology different colorations reaching panchromatic light absorption. However, nearly 45% radiation from sunlight lies in near-infrared (NIR) region, where human cones are not sensitive. This review provides reader key information on how selectively exploit region develop colorless and transparent based DSSC technology. Besides selective NIR absorbers, triptych photoanode, counter-electrode, redox mediator together contributing reach features. Details all components, interplay, an opinion technological limitations NIR-DSSC herein discussed relationship BIPV applications.
