Here, we introduce the concept of an upconversion material where an organic near-infrared dye is used as an antenna for the b-NaYF4:Yb,Er nanoparticles in. Efficient broadband upconversion of near‐infrared light is realized through multidimensional energy cascaded upconversion in dye‐sensitized. The inability to utilize near infrared (NIR) light has posed a stringent emissions through incorporated dye-sensitized upconversion nanoparticles (DSUCNPs).

Our strategy has immediate implications for the use of DSUCNPs to improve the performance of other types of photovoltaic devices. The detailed mechanistic study by Prof. Topics Discussed in This Paper.
The proposed concept can be extended to cover any part of the solar spectrum by using a set of dye molecules with overlapping absorption spectra acting as an extremely broadband antenna system, connected to suitable upconverters.
To overcome this bottle-neck, Prof.
