“…Under solar irradiation; however, those solar cells were durable (20% of the initial efficiency) after 500 h exposure to solar irradiation. 19) In this contribution the lifetime has been reached to 1100 h (50%) under solar irradiation. According to the results, higher stabilities were obtained from the devices containing solution processed ETLs.…”

“…For example, Senocrate et al 18) studied the stability of methylammonium-based PSCs in the presence of temperature, applied voltage, light, oxygen (O 2 ) and water (H 2 O). Moreover, stable and reproducible outcomes were demonstrated for p-i-n structures by Aslan et al 19) Although the selected fullerene derivatives had been compared to each other in order to elucidate the influences on the perovskite device performances, 2022) their effect on device stabilities weren't investigated yet. This contribution demonstrated the effect of electron transport layer (ETL) on the stability of inverted PSCs which is obtained by mixture of Methyl ammonium iodide (MAI), Lead (II) iodide (PbI 2 ) and Lead (II) chloride (PbCl 2 ).…”

This contribution demonstrates the effects of mole ratio, concentration of perovskite components and fullerene derivatives used as electron transport layer (ETL) on the stability and performances of inverted perovskite solar cells (PSCs). C60, C70, PC61BM and PC71BM are selected as ETL materials. Methylammonium iodide (MAI):Lead (II) iodide (PbI 2 ):Lead(II) chloride (PbCl 2 ) are used to form MAPb 2 I 2 Cl which is a mixed halogen perovskite structure. The fabricated perovskite device containing PCBM with optimized concentration and mole ratio gives high power conversion efficiency (PCE) of 9.07% with an open-circuit voltage (Voc) of 0.91 V, short circuit current density of 14.1 mA/cm 2 , and fill factor of 0.71. The lifetime characteristics and the stability are found significantly dependent on the fullerene type. The devices containing PC61BM and PC71BM are able to maintain 50% and 30% of its initial performances, respectively, even after 1100 hours. Overall, the obtained results represent an important step understanding the impacts on the p-i-n type perovskite lifetimes.

“…However, in extreme cases, such as hail, earthquakes, and extreme temperatures, PV modules can be damaged. Perovskite materials are affected by moisture and oxygen, and lead-based perovskites tend to release toxic lead iodide as degradation products that can be transmitted from soil to homes and/or drinking water [25,26]. Scientists have investigated the strategies to prevent lead leakage, holding that the ideal prevention strategy is to trap lead ions quickly.…”

As a novel technology, perovskite solar cells (PSCs) have attracted worldwide attention due to their high photoelectric conversion efficiency (PCE) and low fabricating cost. Moreover, with the development of this technology, PSCs have achieved a great breakthrough in PCE. However, the heavy metal element Pb in PSCs does harm to human health and ecological environments, which restricts the further application of Pb-based PSCs. Under certain circumstances, the leakage of lead will cause serious pollution to the environment. The purpose of this review is to summary and discuss the way of lead leakage suppression. Among them, we pay more attention to the method of packaging technology, chemisorption procession and the limitations of each method. Finally, strategies of highly PCE and non-toxic perovskite devices are proposed.
