“…Pb toxicity triggered attempts for Pb substitution in perovskite PV, by partial or full replacement of Pb using Sn, [44][45][46][47][48] Ge, [49][50][51][52] Sb, [53][54][55] Bi, [56][57][58] Cu, 59,60 and others [61][62][63][64][65] . Among all alternatives, Sn-based perovskites receive the most attention with materials such as methylammonium tin iodide (MASnI 3 ), formamidinium tin iodide (FASnI 3 ), and cesium tin iodide (CsSnI 3 ) 66,67 . However, PCEs of Sn-based PSCs are typically lower than that of Pb-based ones (Figure 3), and once these materials are exposed to ambient, they degrade much faster mostly due to oxidation from Sn 2+ to Sn 4+ which causes loss in V OC.…”

“…Following a study by Llanos et al, 19 precursor substances were selected as the inputs to the hazard assessment. This aligns with certain chemical regulations, which determine the inherent hazard of a product from its chemical inputs at the manufacturing stage, rather than possible end of life issues.…”

“…Although only one lead-free perovskite alternative was explored here, other lead-free perovskite alternatives have been compared elsewhere for solar applications. 19 These perovskite variations may be applicable to displays as well. This performance assessment did not encompass all possible measures of performance.…”

“…18 We have previously published an alternatives assessment on 46 perovskites in solar cells, which has identified the least hazardous alternative as well as the steps needed for that alternative to be more competitive with the highest-performing lead-based material. 19 Alternatives assessment are powerful methods in the context of sustainable chemistry because they enable research on the design and synthesis of safer alternative molecules and materials, but also a simple assessment of emerging one. 20 We hypothesize that this flexible assessment could also be used by substance researchers to identify responsible replacements for Cd-QDs for displays.…”

Light emissive organics and inorganic nanoparticles are substance classes competing for applications in displays in the form of organic LEDs (OLEDs) and quantum LEDs (QLEDs), respectively. Upcoming substance classes (perovskites) and Q-OLED displays also contain novel nanomaterials and organics for these applications. However, the sustainability of these emissive substances is difficult to assess quickly and broadly because of their complexity, their inherently different structures, and their rapid evolution in the literature. We propose the use of an alternatives assessment to compare the hazard, cost, and performance of these competing substances, with a focus on replacing cadmium-containing quantum dots. The cost assessment highlights competitiveness of OLEDs because of their low amounts needed per display, but performance assessments do not identify a preferred alternative. The hazard results indicate there is no clear alternative either, with each novel nanomaterial or organic substance having different negative aspects. These results identify the need for a low-hazard high-performing alternative substance, and the assessment provides a framework for researchers to evaluate their own novel substances.

[29,30] The perovskite solar cell is flexible due to the reduced thickness, which has a promising market applicability. [31,32] However, the reduction of the perovskite absorber layer thickness can reduce the optical path length of light, which in turn lead to unsaturated light absorption of perovskite solar cell.…”

Ultra-thin perovskite solar cell had the advantages of low cost, high efficiency and flexibility, which had significant potential in application. However, a severe optical loss was often observed in the ultra-thin perovskite solar cell due to the insufficient light absorption. In this study, inspired by the efficient light harvesting of hierarchical structure in leaf, a biomimetic leaf-type hierarchical nanostructure was introduced for designing highly efficient ultra-thin perovskite solar cell. In detail, three layers of hexagonal arrays of silica nanoparticles with different radius constructed the biomimetic leaf-type hierarchical structure. The biomimetic leaf-type hierarchical nanostructure was optimized by finite-difference time-domain method combined with particle swarm optimization algorithm to reduce the light reflection and increase the light absorption of the ultra-thin perovskite solar cell. The results indicated that biomimetic leaf-type hierarchical nanostructure could enhance the light absorption of ultra-thin perovskite solar cell by maximum 39% at the long wavelength. The photocurrent of the perovskite solar cell with biomimetic leaf-type hierarchical nanostructure was 8.4% higher than that of perovskite solar cell without biomimetic
