Understanding Perovskite Solar Cells

What is a key advantage of perovskite solar cells compared to traditional silicon-based cells?

• They have a longer lifespan.

• They can be manufactured using simpler processes.

• They are less efficient.

• They are more expensive to produce.

How do perovskite solar cells generate electricity?

• By reflecting sunlight.

• By exciting electrons with sunlight.

• By absorbing heat from the sun.

• By using wind energy.

What innovative application is possible with perovskite solar cells?

• They can be used to power vehicles directly.

• They can be painted onto surfaces to create solar panels.

• They can be used to store energy like batteries.

• They can be used to desalinate water.

What is a major challenge that perovskite solar cells face?

• They degrade quickly when exposed to light.

• They are too heavy for most applications.

• They require rare materials to produce.

• They are not efficient at all.

What environmental concern is associated with perovskite solar cells?

• They require a lot of water to produce.

• They emit greenhouse gases.

• They contain lead, which is toxic.

• They produce a lot of noise.
