6 FAQs about [Perovskite stacked solar cells]

How do perovskite solar cells work?

The carrier transport materials The perovskite solar cell devices are made of an active layer stacked between ultrathin carrier transport materials, such as a hole transport layer (HTL) and an electron transport layer (ETL). The band alignment depends on their energy level, electron affinity, and ionization potential.
