“…The three considered disposal routes were: (i) inertization and residual landfill, (ii) re-use and residual landfill and (iii) reuse and recycling. For re-use, they mean regenerative cycles suggested from Kim et al and Huang et al [76,77]. As largely expected, reuse strategies reduced the values of all impact category.…”

An efficient waste management for emerging photovoltaic (PV) technologies is not mature yet. The problematic aspects along with the possible failure's identification have a pivotal role in modelling the future end-of-life management strategies. The identification of substances of concern (e.g. high cost, low availability, and high toxicity) and valuable materials is a key point to better define the research priorities to improve the eco-design of these technologies. The ultimate goal is to promote the disposal processes which enhance the repair, refurbishment, and recover opportunities and so the profitability of recycling. These studies can also prompt the investigation of innovative materials which are more cost-effective and/ or coming from renewable resources or secondary raw materials. Forecasting the waste management technologies for the emerging photovoltaics is highly challenging. In this context, our purpose is to provide an overview of the critical elements and understand the appropriate corrective improvements towards more sustainable technologies.

“…Manufacturer warranties for conventional crystalline silicon solar cells are valid [20][21][22][23][24][25][26][27][28][29][30] years; yet, module lifetimes could significantly exceed this timespan. PV manufacturers may exit the market before their products meet their end of life.…”

“…[12][13][14] Long-term device and material stability in realistic conditions is currently one of the main limitations and concerns addressed by many research groups and reviews. [15][16][17][18][19] Improvements of stability of PSCs have been under intense research, and advances have been achieved through a multitude of approaches, including ETL free 20 cells, use of dopant free HTM 21 as well as use of HTMs with fluorinated dopants, 22 variations of the metal oxide, 23 multi-cation approach, 24 or design of planar and inverted structures. 25 Another frequently discussed potential drawback of the technology is the use of lead halides in the active material, even if the active material is likely to comprise less than 0.5% of the entire cell mass if a glass substrate is used.…”

Rapid increase in the deployment of photovoltaic installations since the beginning of the century has led to the global capacity exceeding 220GW today. Projections foreseeing growing solar panel deployment rates show that photovoltaic installations will be an important asset in developing a more sustainable world economy. Yet, increasing deployment rates will lead to large volumes of waste photovoltaic modules in the future and large volumes of decommissioned panels can be expected by the middle of this century. Efficient end-of-life treatments will be needed to recover valuable components. Perovskite solar cells were first reported half a decade ago and improvements in efficiency of laboratory scale devices have been achieved at an unprecedented pace. This Perspective discusses some important environmental, regulatory, and practical aspects potentially arising at the end of life of decommissioned perovskite solar cells. With increasing PV deployment rates, resulting waste volumes can be foreseen with a 20-to 30-year lag.

“…30 Furthermore, the four most common methods to produce PSCs were environmentally revised by us. 31 This study also assessed a PSCs regeneration method previously proposed 32,33 applied to the four production methods considered. The aim of this work is to evaluate the ongoing trend of compositional engineering in PSCs through LCA from cradle to gate.…”

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
