Abstract

30-nm-thick sputtered nickel oxide hole-transport layers decrease the likelihood of abrupt reverse-bias breakdown, permanent shorting, and severe thermal damage in perovskite solar cells.

Discussions

• When perovskite solar cells try to operate in the shade, it can cause electrical shorting that can cause permanent damage. This study introduces a new layer that prevents this damage and provides a mo [bsky, 0 points, 1 comments]
