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

The coupling of a copper dye with a copper electrolyte (Cu complexes with the 2,9-dimethyl-1,10 phenanthroline ([Cu(dmp)2]2+/+) and 2-n-butyl-1,10-phenanthroline ligands ([Cu(but-phen)2]2+/+) in a DSSC resulted in a power conversion efficiency (PCE) close to 3% (Table 6 entry 7).[181,182,183]
Summary
It calls for possible adaptation of existing time-resolved characterization techniques to monitor the NIR region. It is given an overview of the concept of transparency, injection, regeneration and recombination processes. It affords to emphasize the possible issues that can be encountered by narrowing the absorber’s bandgap
