Metrics details
Perovskite photovoltaics (PV) have delivered rapid efficiency gains; however, commercial deployment remains constrained by issues related to scale-up, reliability and system-level uncertainties. The field is now limited less by material discovery than by the complex choreography of commercialization. In this Perspective, we reframe the commercialization of perovskite PV as a multidimensional, product-centric evolution spanning materials, manufacturing, standards, policy and market design. In this Perspective, we examine perovskite and perovskite–silicon tandem photovoltaic technologies, focusing on their manufacturing maturity and commercial readiness. We highlight a plateau effect, in which additional laboratory-scale efficiency gains provide limited benefit unless accompanied by improvements in production yield, operational stability and overall factory economics. Drawing on lessons from early pilot lines, regional industrial strategies and analogue technologies such as OLEDs, we highlight the roles of supply chains, adaptive standards and risk capital in creating bankable products. Future research must treat manufacturability, stability, resource constraints and recyclability as primary design variables, and coordinated, application-driven roadmaps are essential to translate perovskite PV from record-setting devices into a credible product.
Perovskite photovoltaics (PV) are no longer constrained primarily by efficiency but by the ability to integrate materials, manufacturing, standards and finance into a coherent product and value chain.
Conventional performance metrics (efficiency and stability of small-area cells) are insufficient for investment and deployment decisions; technology, manufacturing and commercial readiness levels, together with bankability and warranty-compatible reliability data, must guide policy and funding.
Industrially relevant manufacturing routes, robust supply chains and gigawatt-scale factory economics, such as capital expenditure, yield, throughput and learning curves, need to be treated as upfront design constraints rather than downstream optimization problems.
Regional differences in policy, industrial capacity and risk appetite, such as China’s vertically integrated model versus more fragmented ecosystems in Europe and the United States, will shape where and how perovskite PV first reaches meaningful scale.
Perovskite single-junction modules are expected to succeed in differentiated applications such as building-integrated PV, aerospace and agrivoltaics, whereas high-efficiency tandem architectures remain the most promising pathway for mass-market adoption.
