Researchers develop pre-seeding strategy for improving inverted perovskite solar cells

Regular perovskite solar cells (PSCs)—which place the electron-transport layer beneath the perovskite absorber and the hole-transport layer on top—have limitations with respect to large-scale manufacturing and stability. In contrast, inverted PSCs—which reverse the positions of the electron- and hole-transport layers—boast high power conversion potential and good compatibility with scalable solution processing techniques, making them a promising photovoltaic technology.
