Summary
Methionine sulfoxide (MTSO) stabilizes perovskite precursors, enhancing perovskite solar cell (PSC) performance and stability. This approach significantly reduces non-radiative recombination, leading to high power conversion efficiencies and improved device longevity.
Area of Science:
- Materials Science
- Renewable Energy
- Photovoltaics
Background:
- Perovskite solar cells (PSCs) require stable precursors for high-quality film formation and minimal non-radiative recombination.
- Controlling precursor stability is crucial for efficient and durable PSCs.
Purpose of the Study:
- To investigate methionine sulfoxide (MTSO) as a precursor stabilizer and crystal growth mediator for inverted PSCs.
- To enhance perovskite film quality, reduce recombination, and improve device efficiency and stability.
Main Methods:
- Incorporation of MTSO into the perovskite precursor solution.
- Characterization of perovskite film properties (crystallinity, defects).
- Fabrication and testing of inverted PSCs and minimodules, including stability assessments.
Main Results:
- MTSO effectively stabilized the precursor by inhibiting iodide oxidation and passivating traps.
- Achieved power conversion efficiencies of 25.91% for small-area PSCs and 21.96% for minimodules.
- Demonstrated excellent operational and thermal stability, retaining over 90% efficiency after rigorous testing.
Conclusions:
- Rational design of functional molecules like MTSO is key for precursor stabilization and perovskite crystallization.
- MTSO significantly advances the practical development and stability of PSCs.
