Challenges for commercializing perovskite solar cells
Answers
Perovskite solar cells (PSCs) have witnessed rapidly rising power conversion efficiencies, together with advances in stability and upscaling. Despite these advances, their limited stability and need to prove upscaling remain crucial hurdles on the path to commercialization. We summarize recent advances toward commercially viable PSCs and discuss challenges that remain. We expound the development of standardized protocols to distinguish intrinsic and extrinsic degradation factors in perovskites. We review accelerated aging tests in both cells and modules and discuss the prediction of lifetimes on the basis of degradation kinetics. Mature photovoltaic solutions, which have demonstrated excellent long-term stability in field applications, offer the perovskite community valuable insights into clearing the hurdles to commercialization.
Answer:
More energy from the sun hits the Earth's surfacein an hour than humanity uses each year, makingsolar power the most promising candidate whenever the future of energy isdiscussed. The last 25 years transformed solar power from verified oddity to the world's fastest expanding energy source. While the photovoltaic (PV) market is still dominated by siliconsolar panels, perovskitesolar cells (PSCs) have been considered as a 'gamechanger' that caneke out more energy from the sun's photons and be used more flexibly than today's panels.
Making from the most abundant mineral on Earth, PSCs became the frontrunner among all emerging PV technologies. From humble beginnings in 2009 with an efficiency of 3.8% and lasted only minutes, the best PSCs now boast an efficiency of 23.3% and can work for thousands of hours under harsh test conditions.
