Advances in upconversion enhanced solar cell performance
Dye sensitized solar cells: The power conversion efficiency of DSSCs depends on the band gap of the dye used; for the most commonly used ruthenium dye the band gap is ~1.8 eV, which averts the cells from absorbing light beyond ~800 nm. Thus, DSSCs inherently suffer from a low PCE ...
Downconversion Materials for Perovskite Solar Cells
Currently, solar cells include spectrum conversion layers to facilitate the conversion of higher to lower photon energy and vice versa, known as DC and upconversion (UC) processes, respectively. The UC mechanism enables utilization of the incident NIR solar spectrum in the PSCs, which otherwise remains unutilized.
