“…Perovskites from BX 2 -xLBA (with AX addition) refer to breaking coordination bonds and making new bonds, so the ineluctable defects from the B-site or X-site affect the quality of as-formed perovskites; by contrast, (A•••xLBA)BX 3 would more easily form defect-free perovskites. The relationship between perovskite formation routes and perovskite quality, not only for iodide compositions but also for other halide compositions (e.g., PbBr 2 , PbCl 2 ), 54,55 is worth further investigation.…”

The preparation of solution-processed metal halide perovskites is interwoven with research on their intermediate chemistry. In this Perspective, molecule-level insights are provided into how Lewis base additives (LBAs), e.g., DMSO and NMP, facilitate powder-to-film formation processes (i.e., the chemical origin of intermediate structures, structural evolution of intermediate-to-perovskite phase transition, and device-based application of intermediate-evolved perovskites). LBAs interact with Lewis acid species (cationic A+ or B2+ sites) of ABX3 structures with separate probability in terms of coordination bonds or hydrogen bonds to form two types of intermediate structures, inducing significant differences within intermediate-to-perovskite processes. In addition, in-depth understanding of intermediate chemistry favors the multifaceted applications of solution-processed perovskites. A brief summary is finally provided together with a perspective on how intermediate chemistry determines perovskite properties and applications.

“…The clear solar cells fabricated by the thin film technology which combines respectable PCE, longer lifetime, with higher transparency are rarely reported 33 . The transparent films can be achieved by anion substitution, bandgap tuning, and thickness alteration; to date; respectable PCE from 0.1 to 0.5% with transparency between 50 to 70% can be achieved 29 , 34 . Smooth perovskite morphology and good surface coverage are imperative for repeatability and scalability; however, there is no figurative evidence of such in previous studies 29 , 30 , 35 – 37 .…”

With growing population, vertical spaces from skyscrapers are vast. Semi-transparent solar cells enable an effective pathway for vertical energy harvesting. With composition tunability, perovskite materials can be designed with different transparencies and colors. In this work, an ultra-high bandgap layered triple cation perovskite system was developed for the first time to meet the demand of clear optoelectronic applications; low dimensional triple cation perovskite thin films were fabricated using perovskite with the formula (PEA)2(CsxMA0.61-xFA0.39)39(Pb)40(Cl0.88-0.32xBr0.12+0.32x)121, 0 ≤ x ≤ 0.02 with DMSO as the appropriate solvent. The absorption edge of the material is around 410–430 nm, achieving great transparency to visible light. The structural, optical, and photovoltaic performances of the clear perovskite materials are explored with the variation of Cs contents via CsBr. The relation between thickness, transparency, and optoelectronic properties of the clear perovskite materials along with other physical properties were investigated. The highest photovoltaic conversion efficiency (PCE) of clear perovskite solar cells with 1.5% Cs was achieved to be 0.69% under xenon lamp irradiation at 100 mW/cm2 (1.5 mW/cm2 of UVA within 100 mW/cm2) and 5.24% under 365 nm UV irradiation at 2.4 mW/cm2. Photoresponsivity, external quantum efficiency (EQE), and detectivity were also determined for photodetector applications.
