“…employed a solvent‐free method (Figure 33g) to fabricate large‐area perovskite layers. [ 433 ] In this approach, metallic Pb and solid MAI precursors are sequentially deposited on a substrate. The solid MAI precursors are converted to liquid polyiodide (MAI 3(L) ) on exposure to iodine vapor.…”

production have resulted in the reduction of production cost and has facilitated the growth of solar PV technology. [2-6] To make the PV technology more costcompetitive compared to other conventional sources of energy and to further fuel its rapid deployment, the levelized cost of electricity (LCOE) of a PV system needs to be reduced. In a PV system, apart from PV modules, other constituent components such as mounting unit, wiring, inverters, and battery storage constitute about 55% of the total cost. [7,8] These components are generally referred to as the balance of system (BOS). The BOS cost scales proportionally with the area of solar panel installation. An ideal way to reduce the LCOE is by increasing the efficiency of the PV modules. [8] The efficiency of well-established solar cell technologies (Figure 1) such as crystalline silicon (c-Si), gallium arsenide (GaAs) and copper indium gallium selenide (CIGS) are progressing toward the Shockley-Queisser (S-Q) limit, leaving limited room for further improvement in their performance. The thermalization and non-absorption losses incurred in these solar cells mainly restrict their spectral utilization and, consequently, their performance. However, the thermalization losses incurred in single-junction solar cells can be mitigated by combining a wide-bandgap cell with a lowbandgap cell in a multijunction solar cell design, which possesses the ability to achieve efficiencies that surpass the S-Q limit of single-junction solar cells. The practical implementation of multijunction solar cells (MJSCs) utilizing III-V materials have achieved great success in the past. [9] Under 1 sun illumination, LG Electronics and Sharp Corporation have demonstrated monolithic two-terminal MJSC devices using 2-junction (InGaP/GaAs) and 3-junction (InGaP/GaAs/InGaAs) absorber layers to attain power conversion efficiencies (PCEs) of 32.8% [10] and 37.8% [11] respectively. In 2013, Spectrolab utilized a direct bonding technique to grow a lattice-matched 5-junction monolithic MJSC device and demonstrated an efficiency of 38.8% under 1 sun illumination. [12] Very recently, NREL developed a 6-junction monolithic MJSC device to demonstrate a PCE of 39.2% under 1 sun illumination. [13] Despite achieving efficiencies beyond the S-Q limit of singlejunction solar cells, the deployment of III-V MJSCs is limited to space applications due to their high manufacturing cost coupled with slow and complicated fabrication procedures. [14] Metal halide perovskite solar cells (PSCs) have gained tremendous attention due to their high power conversion efficiencies (PCEs) and potential for low-cost manufacturing. Their wide and tunable bandgap makes perovskites an ideal candidate for tandem solar cells (TSCs) with well-established narrow bandgap photovoltaic technologies, such as crystalline silicon and Cu(In,Ga)Se 2 , to boost the PCEs beyond the Shockley-Queisser limit at affordable additional cost. Although perovskite-based TSCs have shown rapid progress over the past few years, they are far from reaching the...

“…Only two families of the perovskites utilize effectively melt preparation techniques—HTSCs and HLHs ( Figure 1 ). In the first case, melt preparation is one of the basic and well-developed approaches ( Table 1 ) while HLH phases have demonstrated such a potential only recently (Petrov et al, 2017a ; Turkevych et al, 2019 ).…”

“…At the same time, an excess of iodine or methylamine forms a self-flux - the room-temperature melts allowing crystallization of HLH perovskites from those liquids (Chen et al, 2017 ; Petrov et al, 2019 ). The recently developed and quite promising RP—MAGIC approach ( Table 1 ) utilizes reactionary polyiodide melts (RPM) to convert thin layers of metallic lead to form a uniform film of light absorbing HLH: Pb + MAI 3 = MAPbI 3 (Turkevych et al, 2019 ). The driving force of this “chemical” crystallization process is that this is not an equilibrium system and has a huge difference in chemical potentials of components between the contacting phases.…”

Widely spread crystal lattices of perovskites represent a natural flexible platform for chemical design of various advanced functional materials with unique features. An interplay between chemical bonding, defects and crystallochemical peculiarities makes the perovskite structure a "LEGO designer" utilizing natural features of chemical elements of the renowned Mendeleev's Periodic Table (PTE) celebrating its 150-year anniversary. In this mini-review, crystal chemistry and bonding features, physical and functional properties, preparation methods and tuning functional properties with periodicity "tools" of the PTE will be exemplified for legendary families of high-temperature superconductive cuprates, colossal magnetoresistive manganites and hybrid lead halides for a new generation of solar cells.

“…For instance, the best-studied photochemical system for fundamental research, such as solid-state reactions in condensed-phase chemistry was based on the polyiodide [4]. The others were mainly used as electrolytes and redox mediators for dye-sensitized solar cells or lithium-iodide batteries [5,6], or as iodine species for perovskite photovoltaics [7,8]. Among these polyiodides, the most studied are the triiodides, and more than 500 triiodide structures have been reported [2].…”

Linearly bonded triiodide chains with fairly small distance between the adjacent iodine ions feature a facile electron transfer and highly anisotropic properties. Here, we demonstrate a novel strategy towards a new one-dimensional linear triiodide DMEDA·I 6 , using chain-type N,N΄-dimethylethanediamine (DMEDA) cation to coordinate triiodine ions. This triiodide has the shortest distance between adjacent I 3 − and good linearity. An estimated electronic band gap of 1.36 eV indicates its semiconducting properties. 100 fold differences both in polarization-sensitive absorption and effective mass were achieved by simulation, with directions parallel and perpendicular to the a-axis of DMEDA·I6. The DME-DA·I6 single crystal-based photodetectors show a good switching characteristic and a distinct polarization-sensitive photoresponse with linear dichroic photodetection ratio of about 1.9. Strongly anisotropic features and semiconducting properties of DMEDA·I 6 make this triiodide system an interesting candidate for polarization related applications.
