Recent studies of the photovoltaic device enhancement via multifunctional luminescent down-shifting films

Abstract A luminescent down-shifting (LDS) layer has attracted mass interest for a few decades due to its simple and straightforward strategy of re-aligning the incident light spectrum to the one of photoactive layers of solar cells, leading to a better spectral response. In addition to the advantages of simple installation applicable to a wide range of conventional photovoltaic (PV) devices, it can pave the way for future PV industries. This report searches the principles of the technique precisely from the elements to consider in choosing materials to the inevitable optical losses led by LDS layers. The tendencies of recent studies and their potential for future applications are examined.
