Perovskite solar technology has rapidly transitioned into a commercially viable solution after just over a decade of intensive global research. Distinguished by its high specific power, cost-effective production, and exceptional performance under low-light conditions, it stands out among photovoltaic technologies for its broad applicability. Hybrid organic-inorganic perovskites uniquely combine the ease of solution processing typical of organic small molecules and polymeric semiconductors with the superior physical properties of high-performance crystalline inorganic semiconductors. This synergy results in a novel material class that harnesses the advantages of both organic and inorganic domains.
To enable the large-scale production of perovskite photovoltaics, the adoption of sustainable, safe, and industry-compatible processing methods is essential. Achieving sustainability begins not only with processing techniques but also at the material level. Solaveni, a Germany-based company, has pioneered the sustainable synthesis of perovskite precursors through innovative green halide chemistry. This presentation highlights the benefits of these novel synthesis routes for organic alkylammonium halides and metal halides, evaluated through life cycle assessment (LCA) and benchmarked against conventional production methods. The LCA examines the environmental impacts of these precursor materials—assessing resource consumption, energy use, and emissions—to provide critical insights into their sustainability profiles and ecological footprints. Furthermore, we introduce novel green recycling approaches for perovskite materials that enable rapid dissolution and recovery, fostering the development of a circular economy.
