“…[125] Fernandes et al introduced the three different organic dyes and showed their absorption spectra below 450 nm and photoluminescence within the P3HT: PCBM active layer absorption range. [126] These are coumarim 7 (C7), coumarim 153 (C153), and kremer blue (KB). The metal/organic complex (Alq 3 ), and europium complex (Eu) were used to compared the dye's optical properties.…”

Organic solar cells (OSCs) in terms of power conversion efficiency (PCE) and operational lifetime have made remarkable progress during the last decade by improving the active layer materials and introducing new interlayers. The newly developed wide bandgap organic donor and low bandgap acceptor molecules covered the absorption from the visible to the near-infrared region. Whereas the incident high energy region (UV) is not in favor of OSCs. Its absorption causes thermalization losses and photoinduced degradation, which hinders the PCE and lifetime of OSCs. Recently, lanthanide and non-lanthanide-based down-conversion (DC) materials have been introduced, which can effectively convert the high-energy photons (UV) to low-energy photons (visible) and resolve the spectral mismatch losses that limit the absorption of OSCs in high energy incident spectrum. Furthermore, the DC materials also protect the OSCs from UV-induced degradation. The DC materials were also proposed to cross the Shockley-Queisser efficiency limit of the solar cell. In this review, the need for DC materials and their processing method for OSCs have been thoroughly discussed. However, the main emphasis has been given to developing lanthanides and non-lanthanides-based DC materials for OSCs, their applications, and their impact on photovoltaic device performance, stability, and future perspectives.

“…Since first reported by Hovel et al in 1979, LDS layers have been considered as one of the effective strategies to improve the efficiency of solar cells. So far, rare-earth doped phosphors, − organic luminescent dyes, , and quantum dots (QDs) ,− have been reported as LDS materials. Among them, colloidal semiconductor QDs have attracted much attention due to their outstanding photoluminescence ,, and tunable emission wavelength by controlling their size. , Ternary I–III–VI semiconductor QDs, e.g., Ag- and Cu-based, play a pivotal role as an alternative to environmentally unfriendly Cd- and Pb-based QDs in optoelectronic devices.…”

Colloidal AgIn 5 S 8 /ZnS quantum dots (QDs) have recently emerged as a promising, efficient, nontoxic, down-shifting material in optoelectronic devices. These QDs exhibit a high photoluminescent quantum yield and offer a range of potential applications, specifically in the field of photovoltaics (PVs) for light management. In this work, we report an eco-friendly method to synthesize AgIn 5 S 8 /ZnS QDs and deposit them on commercial silicon solar cells (with an active area of 7.5 cm 2 ), with which the short-circuit current (J SC ) enhanced by 1.44% and hence the power conversion efficiency by 2.51%. The enhancements in PV performance are mainly attributable to the improved external quantum efficiency in the ultraviolet region and reduced surface reflectance in the ultraviolet and near-infrared regions. We study the effect of QD concentration on the bifunctions of downshifting and antireflection. The optimal 15 mg/mL QDs blade-coated onto the Si solar cells realize maximum current generation as the reflectance loss in the visible wavelength is compensated by the minimized reflection in the near-infrared region.

“…A luminescent downshifting (LDS) layer with phosphors is an active area of research toward improving the conversion efficiency of solar cells. Phosphors for the LDS layer include organic dyes, 4–8 rare-earth complexes, 2,9–11 and inorganic nanoparticles. 12–19 Organic dyes and rare-earth complexes are not suitable for use in solar devices; a durability of more than 20 years is required for solar modules.…”
