Keywords Patent analysis Collaboration Inventor Assignee Solar cell PV system Introduction With the help of information and communication technologies, knowledge-based econo-mies emerge when people group in an intense effort to co-produce new knowledge (i.e., produce and exchange) (David and Foray 2002). Some research views the increasing collaborative
This can be explained by the dynamic inventive pattern of solar photovoltaic technologies that several new types of solar photovoltaic cells emerged during the focal period opening up windows of opportunities (Kalthaus, 2019), as well as the rapid international transfer of codified knowledge concerning solar photovoltaic technology (Binz & Truffer, 2017), allowing
Despite improvements in using materials more efficiently, the PV industry''s demand for minerals is set to expand significantly. In the IEA''s Roadmap to Net Zero Emissions by 2050, for instance, demand for silver for solar PV manufacturing in 2030 could exceed 30% of total global silver production in 2020 – up from about 10% today. This rapid growth, combined with long lead
