A Perspective on the Commercial Viability of Perovskite Solar Cells

摘要

Perovskite solar cells (PSCs) have received a large amount of research funds dueto their potential as a frontrunner in a new generation of solar cells; consequently,the desire to commercialize this technology is mounting. In this roadmap, theknowledge and the technological gaps between laboratory and industry arecritically analyzed from the perspective of 5S criteria (Stability, Safety,Sustainability, Scalability, and Storage). To avoid any favoritism in the argumentstoward commercializing this technology, herein, the average parameters of PSCs(photoconversion efficiency, durability, cost, manufacturability, and sustainability)estimated from previous studies are analyzed and discussed. Uniqueopportunities for PSCs in their current stage of achievements are identified,where application-driven, instead of performance-driven, developments areshown to favor their commercialization. Efforts required to improve the averageperformance of PSCs to state-of-the-art levels are also identified and discussed.
