Exploring prospective materials for energy production and storage is one of the biggest challenges in this century. Solar energy is arguably the most important amongst various renewable energy resources, due to its wide availability and sustainability with lowest environmental impact. Metal halide perovskites have emerged as a class of semiconductor materials with unique properties including tuneable band gap, high absorption coefficient, broad absorption spectrum, high charge carrier mobility and long charge diffusion lengths, which enable a broad range of photovoltaic and optoelectronic applications. Since the first embodiment of perovskite solar cells showing a power conversion efficiency of 3.8%, the device performance has now been boosted up to a certified 21% within a few years. In this perspective, we summarize differing forms of perovskite materials produced via various deposition procedures, focusing on their energy related applications, and discuss current challenges and possible solutions, with the aim of stimulating potential new applications.

“…However, HOIP materials suffer from poor stability under external stresses, especially moisture, heat and light, due to their low formation energy (approximate 0.1-0.3 eV) [11][12][13][14]. Once water approaches the perovskite surface, it prefers to strongly bind Pb cations, and then the structure degrades within only 8.5 ps [15,16].…”

To enhance the stability in humidity is very crucial to hybrid organic-inorganic lead halide perovskites in a broad range of applications. This report describes a coating stratergy of perovskite nanocrystals via polymethylmethacrylate-introduced ligand-assisted reprecipitation, using the interactions between the Pb cations on the surface of perovskite nanocrystals and the functional ester carbonyl groups in polymethylmethacrylate framework. The hydrophobic framework shields the open metal sites of hybrid organic-inorganic lead halide perovskites from being attacked by water, effectively retarding the diffusion of water into the perovskite nanocrystals. The as-prepared films demonstrate high resistance to heat and moisture. Additionally, the introduction of polymethylmethacrylate into ligand-assisted reprecipitation can effectively control the bulk precipitation and promote the stability of the perovskite solution.

“…[3][4][5] However, in order to produce them at a large scale, stability and reproducibility issues must be overcome. [6][7][8][9] Thus far, much research on PSCs has been oriented towards compositional engineering. [3][4][5]10 Perovskites with outstanding photovoltaic properties have a distinctive structure, composed by three atoms according to the formula ABX 3 , where A corresponds to a monovalent organic/inorganic cation, B corresponds to a divalent inorganic cation (commonly Pb) and X corresponds to a halide anion (Cl, Br and I).…”

After the great initiation of perovskite as a photovoltaic material, laboratory efficiencies similar to other photovoltaic technologies already commercialised have been reached. Consequently, recent research interests on perovskite solar cells try to address the stability improvement as well as make its industrialisation possible. Record efficiencies in perovskite solar cells (PSCs) have been achieved using as active material a multiple cation/anion perovskite by combining methylammonium (MA) and formamidinium (FA), but also Cs cation and I and Br as anions, materials that also have demonstrated a superior stability. Herein, the environmental performance of the production of such perovskite films was evaluated via life cycle assessment. Our study points out that multiple cation/anion perovskite films show major detrimental environmental impacts for all categories assessed, except for abiotic depletion potential, when they are compared with a canonical perovskite MAPbI 3 . In addition, a closer analysis of the materials utilised for the synthesis of the different multiple cation perovskites compositions revealed that lead halide reagents and chlorobenzene were the most adverse compounds in terms of impact. However, the former is used in all the perovskite compositions and the later can be avoided by the use of alternative fabrication methods to anti-solvent. To this extent, FAI, with the current synthesis procedures, is the most determining compound as it increases significantly the impacts and the cost in comparison with MAI. A further economic analysis, exposed that multiple cation perovskites need a significantly higher photoconversion efficiency to produce the same payback times than canonical perovskite.2
