The second test paper besides efficiency
The laboratory efficiency of perovskite solar cells continues to be refreshed, but the long-term stability under the combined effects of heat, light, humidity and electrical bias still determines whether it can truly make it out of the laboratory.
Pay equal attention to microscopic defects and macroscopic packaging
Grain boundaries, vacancies and interface energy levels need to be addressed at the material level; at the same time, barrier films, edge sealing and thermal management must also be incorporated into the same engineering design.
Saved this one for a deeper discussion with my classmates.
I had never thought about the material side of this problem before.
The examples make the science much easier to follow.
A very approachable introduction to the topic.
This connects the classroom concept with a real application nicely.
The explanation of the mechanism was especially helpful.
Looking forward to reading more about the engineering challenges.
This gave me a useful starting point for further research.
The structure is clear and the pacing works really well.
This is a wonderfully clear way to explain a complicated idea.
