| Abstract: |
Perovskite solar cells (PSCs) have made game changing progress during the last decade and reached a power conversion efficiency (PCE) of up to 25%. Furthermore, the development of material chemistry, structure design, active layer composition, and process engineering, etc. have contributed to improving PSCs stability. The significant PCE losses experienced by PSCs are related to spectral mismatch between the incident solar spectra and absorption range of active layer, which thereby limits the PCE. Besides PSCs performance, the photoinduced degradation is also a major concern. Recently, lanthanide (rare-earth) and non-lanthanide based down-conversion (DC) materials have been introduced to resolve these spectral mismatch losses as well as to reduce the photoinduced degradation. The DC materials improve the photovoltaic performance by converting ultraviolet (UV) light to visible, also providing UV shielding, and thus contribute to increasing the efficiency as well as stability of the PSCs. Moreover, the Shockley-Queisser efficiency limit of the solar cell could be crossed with the help of DC materials. In this review, we have thoroughly discussed the importance, processing, and the reported DC materials for PSCs. Furthermore, the development of DC materials and their impact on PSCs performance and stability, along with their future perspectives has been focused. |
