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

“…Furthermore, the low deposition rates extend further the deposition time and subsequently, the energy consumption and carbon emissions. Five studies have included balance-of-system (BOS) equipment, which is all the related equipment that is needed to allow the functioning of the photovoltaics, cables, inventers, switches and more, in their system boundaries [17,19,21,22,24]. All the studies have shown that BOS is also a very important contributor for both climate change impact and primary energy consumption.…”

Green and Clean: Reviewing the Justification of Claims for Nanomaterials from a Sustainability Point of View

Nanotechnology is an emerging technology with the potential to contribute towards sustainability. However, there are growing concerns about the potential environmental and human health impacts of nanomaterials. Clearly, nanomaterials have advantages and disadvantages, and a balanced view is needed to assess the overall benefit. The current "green and clean" claims of proponents of nanomaterials across different sectors of the economy are evaluated in this review study. Focusing on carbon emissions and energy use, we have reviewed 18 life cycle assessment studies on nanomaterials in the solar, energy, polymer, medical and food sectors. We find that the "green and clean" claims are not supported for the majority of the reviewed studies in the energy sector. In the solar sector, only specific technologies tend to support the "green and clean" claims. In the polymer sector, only some applications support the "green and clean" claims. The main findings show that nanomaterials have high cradle-to-gate energy demand that result in high carbon emissions. Synthesis of nanomaterials is the main contributor of carbon emissions in the majority of the studies. Future improvements in reducing parameter uncertainties and in the energy efficiency of the synthesis processes of nanomaterials might improve the environmental performance of nanotechnologies.

Following the unprecedented rise in photovoltaic power conversion efficiencies during the past five years, metal-halide perovskites (MHPs) have emerged as a new and highly promising class of solar-energy materials. Their extraordinary electrical and optical properties combined with the abundance of the raw materials, the simplicity of synthetic routes, and processing versatility make MHPs ideal for cost-efficient, large-volume manufacturing of a plethora of optoelectronic devices that span far beyond photovoltaics. Herein looks beyond current applications in the field of energy, to the area of large-area electronics using MHPs as the semiconductor material. A comprehensive overview of the relevant fundamental material properties of MHPs, including crystal structure, electronic states, and charge transport, is provided first. Thereafter, recent demonstrations of MHP-based thin-film transistors and their application in logic circuits, as well as bi-functional devices such as light-sensing and light-emitting transistors, are discussed. Finally, the challenges and opportunities in the area of MHPs-based electronics, with particular emphasis on manufacturing, stability, and health and environmental concerns, are highlighted.
