展示研究成果

Good morning, everyone. Thank you for attending today's presentation. My name is Dr. Alex Chen, and I'm a senior researcher at the Institute for Advanced Materials. Today, I'll be presenting our latest findings on the 'Synthesis and Characterization of Novel Perovskite Solar Cells'.

To begin, let's briefly look at the current landscape of solar energy and the limitations of traditional silicon-based photovoltaic devices. Our research aims to address these challenges by exploring the potential of perovskite materials.

As you can see from this slide, our optimized synthesis method has significantly improved the power conversion efficiency to a record 24.5%, while also demonstrating remarkable long-term stability under humid conditions. These results are incredibly promising.

Dr. Chen, fantastic presentation. I have a question regarding the stability data you presented. Could you elaborate on the specific environmental conditions used for the long-term stability testing, especially concerning temperature fluctuations?

Thank you for the excellent question. We conducted the stability tests under a controlled environment with relative humidity maintained at 85% and temperature cycled between 25 and 60 degrees Celsius over a 1000-hour period. We also performed accelerated aging tests, but those data are for a follow-up publication.

Following up on that, did you observe any material degradation or morphological changes after the long-term stability tests that might account for the slight reduction in efficiency seen at the very end of your data set?

That's a very keen observation. We did indeed notice some minor recrystallization at the grain boundaries, which we believe contributes to that slight drop. Further work is underway to mitigate this issue through interface engineering. Does that address your question?

Yes, completely. Thank you.

Are there any other questions from the audience? If not, I'd like to thank you all again for your time and attention. We look forward to sharing more updates on this research in the near future.
