Perovskite solar cells (PSCs) with a power conversion efficiency (PCE) overpassing 25% have proved to be the most promising competitor for the next‐generation photovoltaic technology. Massive efforts are devoted to the improvement of the performance and stability of PSCs, whereas the hole transport layer (HTL) has attracted significant interest. Among diverse hole transport materials, poly[bis(4‐phenyl)(2,4,6‐trimethylphenyl)amine (PTAA) is one of the most promising candidates due to its ease of fabrication, transparency to visible light, mechanical flexibility, conductivity, and stability. Over the past few years, there has been an increasing amount of research using PTAA as the HTL first in n–i–p and then in p–i–n PSCs with extended applications in flexible, large‐area, and tandem devices. Herein, a progress review on PTAA for PSC applications is provided, which enables a better understanding of the advantages and disadvantages of PTAA, as well as the approaches to fully realizing its tremendous potential. The emerging and promising research directions for PTAA‐based PSCs are discussed, shedding light on the practical applications of PTAA.

Downconversion Materials for Perovskite Solar Cells

et al. 2022

Perovskite solar cells (PSCs) have made game‐changing progress in 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, process engineering, etc. has 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 the active layer, which thereby limits the PCE. Besides PSCs’ performance, the photoinduced degradation is also a major concern. Recently, lanthanide (rare‐earth) and nonlanthanide‐based downconversion (DC) materials have been introduced to resolve these spectral mismatch losses as well as 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 PSCs. Moreover, the Shockley–Queisser efficiency limit of the solar cell can be crossed with the help of DC materials. In this review, the importance, processing, and the reported DC materials for PSCs are thoroughly discussed. Furthermore, the development of DC materials and their impact on PSCs’ performance and stability, along with their future perspectives, are focused.

Despite recent increases in perovskite solar cell (PSC) efficiencies, long‐term stability remains a barrier to manufacturing and marketing. SnO2 electron transport layers enable the low‐temperature processing of planer n–i–p structured PSCs. However, ultraviolet radiation damages to the interface between the electron transport layer and the perovskite (PVK), which is a significant issue for n–i–p configuration. Herein, the insertion of a thin CeO2 passivation layer between the SnO2 and PVK is investigated to block the interface degradation. This CeO2 layer improves charge extraction and reduces defects in the PVK/CeO2 interface, resulting in 22.71% power conversion efficiency (PCE) compared to the pristine SnO2 PSC devices, which has a PCE of 20.7%. In addition, after 1700 h of storage at room temperature and 5%–8% RH (dry box), the PCE stability of the reinforced SnO2–CeO2 PSC devices drops from 22% to 19%, whereas that of the pristine SnO2 PSC devices drops from 20% to 16%.
