“…Except the large efficiency gap mentioned above [15,16], another great challenge that slows down the commercial application of PSCs is the poor stability induced by humidity [17], temperature [18], and illumination [19]. Fundamental understanding the structure performance relationship is the key point for efficiency and stability improvements.…”

Long-term stability and power conversion efficiency of perovskite solar cells are strongly affected by their precursor compositions and intermediate phases during the fabrication process. In general, complex chemical reactions happen in a short time scale during the nucleation and crystal growth steps. However, the ex-situ characterization probes cannot capture the dynamics of perovskite film formation and degradation. In this review, we discussed the ambient air-compatible in-situ characterization probes that are used to monitor the evolution of the structural, morphological, and optoelectronic properties of perovskite films, which provides a deep understanding of the perovskite crystal formation process.

“…Perovskite materials, whether inorganic or hybrid, possess exciting electronic and photoelectronic properties and have inspired researchers to exploit them for plausible applications in optoelectronic and photovoltaic devices. − Developing a hybrid perovskite (CH 3 NH 3 PbI 3 ) based solar cell efficiency of over 25% is regarded as a breakthrough in perovskite materials research worldwide . Most of the previous reports on upscaled perovskite solar cells show an efficiency range 10–17%. − Despite showing high promise in small-scale and upscaled devices, − the successful commercialization of perovskite photovoltaic solar cells (PSC) has been hindered primarily because of two issues: the stability of PSC and the toxicity of lead (Pb) . The stability can be generally divided into photostability, , thermal stability and chemical stability (influence of atmospheric O 2 and H 2 O). − Numerous studies have been reported so far to address the issue in-depth and look for possible remedies .…”

Electric field and light induced ion migration resulting in poor stability is a key hindrance for the development of perovskite solar cells and devices. Methods to identify the pathways of ion migration and subsequently to develop strategies to suppress them are prerequisites to develop perovskite solar cells with improved stability and high efficiency. In this report, we probe ion migration through the observation of negative photocurrent (I) measured by temperature (100−283 K) dependent transient photocurrent response characteristics (I−t) as well as current−voltage (I−V) characteristics under dark and light conditions. Controlled experiments are carried out on lead (Pb)-free hybrid perovskite (CH 3 NH 3 ) 3 Bi 2 (Br x Cl 1−x ) 9 (where x = 0, 0.33, 0.44, 0.55, 0.66) samples with varying Br/Cl ratio. The mixed halide system is found to have the lowest bandgap of 2.557 eV corresponding to bromine content x = 0.44. Incorporation of bromine has a visible effect on the flake-like microstructures of the perovskite materials. While, the I−V characteristics confirmed the ion migration and phase segregation of halide ions and their irreversibility in the system, the I−t profiles showed the existence of an induced electric field acting in the direction opposite to the applied field due to the migration of halide ions and creation of halide vacancies, resulting in a negative photocurrent. The I−t profiles are found to be reversible and strongly dependent on temperature as well as the Br/Cl ratio. I−V characteristics under light illumination also display hysteresis behavior, the effect of which gets reduced with the increase in bromine content. The photocurrent hysteresis and its irreversibility upon change in scanning direction of the applied electric field is believed to be arising out of ion migration dominant in perovskite materials. A comprehensive analysis has been made to infer the charge transfer process and ion migration in the mixed halide system contributing to the stability and efficiency of perovskite solar cells and devices.

“…[1][2][3] The up-to-date highest certified power conversion efficiency (PCE) of smallsized PSCs has reached 26.1%, [4] while the PCEs of large-scale perovskite solar modules (PSMs) are still far behind.

Converting PbI2 residues into low‐dimensional perovskites through post‐treatment with ammonium‐based large cations can passivate 3D perovskites, thus has emerged as an effective strategy to improve the performance of perovskite solar cells (PSCs). Herein, a dramatically improved efficiency is demonstrated for PSCs based on a two‐step‐processed FAPbI3 perovskite via post‐treatment with formamidinium (FA)‐based benzamidine hydrochloride (PFACl), outperforming the commonly used methylamine (MA)‐based benzylamine hydrochloride (PMACl). With an in‐depth exploration of the crystal structures and morphology changes of the FAPbI3 perovskite upon the PFACl post‐treatment, the preferential formation of 1D rather than 2D structures on the 3D perovskite film is identified. In contrast to the 2D counterpart, the more energetically favorable 1D structure enables a more effective elimination of PbI2 residues. As a consequence, the PFACl‐induced 1D/3D perovskite film is endowed with smoother morphology, more uniform surface potential distribution, lower trap density, faster charge transfer, and better film stability than the PMACl‐induced 2D/3D perovskite and control films, demonstrating champion efficiencies of 24.9% for a small‐size PSC, 23.6% for a 1 cm2 large‐size PSC, and 21.2% for a 5 × 5 cm2 mini‐module, which is the highest among the perovskite solar mini‐modules using the two‐step deposition method.
