Summary
Ultrastable Dion-Jacobson perovskites offer a solution for the long-standing stability concerns in perovskite photovoltaics. Blade-coated solar cells demonstrate high efficiency and exceptional durability under harsh environmental conditions.
Area of Science:
- Materials Science
- Renewable Energy
- Solid-State Physics
Background:
- Perovskite photovoltaics (PV) face significant stability challenges hindering commercialization.
- Developing stable perovskite materials for efficient solar energy conversion is crucial.
Purpose of the Study:
- To demonstrate ultrastable Dion-Jacobson (DJ) perovskites for photovoltaic applications.
- To investigate the performance and stability of blade-coated DJ perovskite solar cells.
Main Methods:
- Synthesis of a series of DJ perovskites with the general formula (1,4-cyclohexanedimethanammonium)(methylammonium)n-1PbnI3n+1.
- Fabrication of solar cells using scalable blade-coating technology.
- Comprehensive stability testing under various environmental conditions (humidity, heat, operational stress).
Main Results:
- DJ perovskite solar cells (nominal n=5) achieved a maximum stabilized power conversion efficiency (PCE) of 19.11%.
- Un-encapsulated cells retained 92% of initial efficiency after 4000 hours at ~90% relative humidity.
- Cells showed remarkable thermal stability (85 °C for >5000 hours) and operational stability (MPP operation at 45 °C for >6000 hours).
Conclusions:
- The developed DJ perovskites exhibit exceptional stability, addressing a key limitation in perovskite PV.
- Scalable blade-coating technology is suitable for producing stable and efficient perovskite solar cells.
- These findings pave the way for practical applications of highly durable perovskite solar technology.
