The PRiME Lecture - “Perovskite Solar Cells: Past 10 Years and Next 10 Years” by Nam-Gyu Park

Since the first report on the 9.7% efficient and 500 h-stable solid-state perovskite solar cell (PSC) in 2012, following two seed reports on perovskite-sensitized liquid junction solar cells in 2009 and 2011, research on perovskite photovoltaics has surged due to the high power conversion efficiency (PCE) obtainable via facile fabrication procedures. As a result, a PCE of 25.2% was recorded in 2019. According to Web of Science, the number of publications on PSCs has grown exponentially since 2012, leading to more than 15,500 accumulated papers, which indicates that PSCs are considered as promising next-generation photovoltaics. Over the past 10 years, high photovoltaic performance has been realized through compositional engineering, device architecture, and new coating methodologies. To reach a theoretical efficiency over 30% and commercialization of PSCs, further studies on recombination and developments of scalable technologies are required. In this talk, the importance of interfacial and grain boundary engineering to reach the theoretical efficiency with voltage over 1.3 V and fill factor over 0.9 is emphasized. For commercialization, new materials may be required because the current precursor mixture is problematic due to the underlying aging effect. We developed cost-effective materials based on delta FAPbI3 powder for reproducibly high efficiency PSCs. Large-area uniform perovskite coating is also important in upscaling PSCs. Acetonitrile-based and 2 methoxy ethanol-based coating solutions were developed for large-area perovskite films. In addition, additive engineering and bifacial stamping technique were found to be effective ways for upscaling PSCs. Stability is also discussed throughout the talk.

3:05 Do not lie!
The developer of the Perovskite solar cell is a Japanese professor; Tsutomu Miyasaka!

You know, Tatayanas here at RUclips has a GREAT Pirozhki recipe that I highly recommend:) By the way, I'm drunk on Jim Beam© whiskey, and loving it! Take care everyone:) Happy Holidays.

Thanks for the Wonderful talk!

[@abelectronics9031]

Thanks so much this material is very useful for beginners

[@abdulsameeu2560]

Sorry, I couldn't get the first two suggested coating methods. could anyone write it here?

[@icare7151]

Continuous range processes should be considered.

[@hardcorepapaa]

What is lifetime of pevroskite solar cell?

[@ShubhamGupta-jz8lo]

As of today, its hardly 1 year.

@Will Swifttheir cost is half of the silicon solar cell with a 25.6% efficiency as of now. We have two issues with perovskite solar cell
1. their stability
2. Toxicity
the most efficient solar cell is a lead halide perovskite solar cell with 10000h lifetime in the ambient condition which is very low compared to the silicon solar cell (it has 27% power conversion efficiency and 25 years lifetime)
Double perovskite solar cells are more stable than single perovskite solar cells but their efficiency is low compared to the single perovskite solar cell. In the solar cell, there is so-called golden triangle consists
1. Efficiency
2.cost
3. stability
if you increase one parameter others will be affected, if you increase efficiency, stability will decrease or cost will increase likewise if you increase stability efficiency will be decreased.
