Summary: Defect-induced charge non-radiative recombination loss at perovskite/charge transport layers interfaces is a major issue for the efficiency and stability of flexible perovskite solar cells. This study proposes a comprehensive strategy to reduce the defect density at these interfaces, using TMPU material to improve conductivity of SnO2 and passivate the SnO2/perovskite interface defects, and TMFS layer to suppress perovskite surface defects and improve environmental stability. With this dual-interface engineering strategy, the optimized flexible and rigid PSCs achieve higher photoelectric conversion efficiency compared to the pristine devices, and the flexible device also demonstrates excellent mechanical durability.

Summary: This study demonstrates efficient low-temperature flexible perovskite solar cells by improving the interfacial contact between the electron-transport layer (ETL) and the perovskite layer. The incorporation of titanium tetrachloride (TiCl4) effectively decreases the adsorbed oxygen active sites and oxygen vacancies of the flexible tin oxide (SnO2) ETL layer. This leads to improved charge collection efficiency and higher solar cell efficiencies up to 23.7% at 218 K, opening up new possibilities for flexible photovoltaic technology in low-temperature environments.

Summary: This study presents a heterointerface engineering strategy using reduced L-glutathione (GSH) as a multifunctional molecule to improve the efficiency and stability of perovskite solar cells (PSCs). The introduction of GSH improves the crystallization of SnO2, enhances the affinity between SnO2 and perovskite, and passivates the defects at the heterogeneous interfaces while accelerating electron transport. The PSCs based on the GSH-SnO2 layer achieve a significantly increased power conversion efficiency (PCE) of 21.66% with no noticeable hysteresis and exhibit better environmental stability.

Summary: Due to its excellent optoelectronic properties, the power conversion efficiency of halide perovskite solar cells (PSCs) has rapidly increased to 25.7%. However, lead poisoning presents a significant obstacle to the deployment of PSCs. Tin is a promising alternative due to its similar electric and electronic properties to lead and lower toxicity. This review evaluates the characteristics and performance of quasi-2D Sn-based perovskites and proposes alternative strategies for improving the efficiency and stability of tin-based PSCs.

Summary: Functionalized oxo-graphene nanosheets (Dec-oxoG NSs) are synthesized to manage excess lead iodide (PbI2) and improve the stability of perovskite solar cells. Dec-oxoG NSs provide anchoring sites to bind the excess PbI2 and passivate perovskite grain boundaries, resulting in reduced charge recombination loss and enhanced electron extraction. The inclusion of Dec-oxoG NSs leads to a high efficiency of 23.7% in inverted (p-i-n) perovskite solar cells, with 93.8% of their initial efficiency retained after 1,000 hours of continuous one-sun illumination and high stability under thermal and ambient conditions.
