Nanostructured organosilicon luminophores in highly efficient luminescent down-shifting layers for thin film photovoltaics

Optimum Luminescent Down-Shifting Properties for High Efficiency and Stable Perovskite Solar Cells

“…8,9,16,49 The remaining solar cell dimensions and materials are based on previous results from optimizations centered on maximizing the optical performance of front LT structures on the PSCs, 49 which are summarized in Table S1 of Supplementary Material. A preferential implementation of luminescent down-shifting (LDS) materials is via their embedment in a polymeric matrix used as the cell's encapsulant, 24,25,50 as sketched in Figure 1 a) and b), which is generally several micrometers thick. 24,50 Therefore, such DS encapsulant layer was modelled as the background medium over the cells' structures.…”

Test of SensL SiPM coated with NOL-1 wavelength shifter in liquid xenon

“…It has the very high energy transfer efficiency of the electronic excitation from the outer fragments of a molecule absorbing the light at the short wavelengths, to the inner fragment having the high photoluminescence quantum yield (QY) at longer wavelengths [6,7]. This type of luminophores are of interest for various technical applications [5,8]. The NOL-1 type was chosen for shifting of the VUV light emission of liquid xenon (175 nm) to the region of maximal PDE of SiPM (420 nm).…”

Tuning the optical properties of luminescent down shifting layers based on organic dyes to increase the efficiency and lifetime of P3HT: PCBM photovoltaic devices

“…They possess a high absorptivity and PLQY, are abundant and their cost is lower than other candidates, such as Europium complexes, quantum dots or nanophosphors [29]. However, as pointed out by Uekert et al [30], organic dyes generally have narrow absorption bands and, as a rule of thumb in organic compounds, exhibit relatively low photo stability, mainly with exposure to UV radiation. The purpose of this work is to optimise the properties of LDS layers based on organic dyes to produce a significant further increase in the current density generated by photovoltaic cells having P3HT:PCBM as the active layer.…”
