The numerous advantages of perovskite-based photovoltaic cells have been well acknowledged over the past several years. These include demonstrated high efficiency, direct and tunable bandgap, flexible and forgiving synthesis routes. Equally well-known are the challenges associated with material stability, moisture sensitivity, and the presence of lead in the most common formulation. A commercial product not only must meet those basic requirements but numerous others to meet customer and commercial requirements. Other commercial thin-film PV technologies including CdTe and CIGS spent many years going from the lab to a fabrication environment. Commercial Si solar panels, 92% of the market, have warranties of 10 or more years and expected usable lifetimes longer than 25 years, Perovskite technology must compete with those figures and for the case of 2-terminal tandem configurations with silicon, must impact the module reliability negatively. We compare reliability of silicon PV with perovskite.In order to have a complete understanding of the commercial viability of a PV process, we will contrast the life cycle assessment (LCA) of perovskite PV systems with other commercial PV technologies. The LCA data will help forecast the manufacturing process and predict the commercial success potential of perovskite systems. We will also examine the environmental impact of the Pb content and present a view of the statutory and regulatory situation that applies to this technology. Finally, we will look at requirements for recycling that may be necessary.
