This technoeconomic analysis shows that perovskite solar cells can emerge as a cost leader in photovoltaic power generation.
A PK<sub>Sn,Pb</sub>/PK<sub>Pb</sub> tandem was found to be the most promising PV technology for lowering environmental impacts from solar PVs.
Carbon (C) cycling in Lake Superior was studied within the Keweenaw Interdisciplinary Transport Experiment (KITES) project to assess (1) whether lake is net heterotrophic, (2) sources, sinks and residence time for dissolved organic carbon (DOC), (3) importance of terrigenous C subsidies, (4) factors limiting flow through bacteria. During 3 years fieldwork, measurements were made spatial temporal distributions pools rates photosynthesis, community respiration, bacterial production....
Two-terminal tandem perovskite (PK) cells are considered a promising option for future photovoltaic (PV) market due to the rapid improvements in their power conversion efficiencies. However, large-scale adoption requires better understanding on energy performance of these PVs. In this paper, life-cycle consumptions two-terminal solar consisting lead-based PK top prepared bottom copper indium gallium selenide, zinc tin and monocrystalline silicon evaluated. The payback time (EPBT) return...
Rainwater harvesting (RWH) is being used more often today as a water supply and stormwater management green infrastructure (GI). In recent years, GIs in urban engineering have gained attention due to their lower lifecycle costs—in both implementation operation phases—rather than traditional gray approaches. The research described the present paper compared of RWH systems approaches previously designed part long-term control plan (LTCP) for combined sewer overflow (CSO) Toledo, Ohio....
With solar photovoltaics (PV) playing an increasing role in our global energy market, it is now timely and critical to understand the end of life management panels. Recycling panels can be important pathway, possibly recovering a considerable amount materials adding economic benefits from currently installed Yet, date, costs recycling, especially when externality resulting environmental pollution are considered, largely unknown. In this study, we quantified private recycling crystalline...
Summary Current aggregate and top‐down approaches in life cycle sustainability assessment (LCSA) generally fail to account for spatial, temporal, emergent behavioral dynamics simultaneously during the inventory stage. We discuss key characteristics captured by complex system (agent‐based modeling [ABM] particular) context of LCSA. It is understood that integrating ABM, can be addressed propose a general concept integrate ABM into current building standards. then use hypothetical example...
This paper discusses the modeling of anion and cation leaching from complex matrixes such as weathered steel slag. The novelty method is its simultaneous application theoretical models for solubility, competitive sorption, surface precipitation phenomena to a system. Selective chemical extractions, pH dependent experiments, geochemical were used investigate thermodynamic equilibrium 12 ions (As, Ca, Cr, Ba, SO4, Mg, Cd, Cu, Mo, Pb, V, Zn) with aqueous complexes, soluble solids, sorptive...
An ex-ante life cycle inventory was developed for single walled carbon nanotube (SWCNT) PV cells, including a laboratory-made 1% efficient device and an aspirational 28% four-cell tandem device. The environmental impact of unit energy generation from the mono-Si technology used as reference point. Compared to monocrystalline Si (mono-Si), impacts SWCNT ∼18 times higher due mainly short lifetime three years. However, even with same lifetime, cell had lower than mono-Si. effects efficiency on...
Given the expansion of urban agriculture (UA), we need to understand how this system provides ecosystem services, including foundational societal needs such as social cohesion, i.e., people’s willingness cooperate with one another. Although cohesion in UA has been documented, there is no framework for its emergence and it can be modeled within a sustainability framework. In study, address literature gap by showing popular cascade services model modified include structures. We then transform...
