Abstract
- We demonstrate all thermal vapor-deposited CsSnBr 3 perovskite solar cells. The cell architecture consists of a planar CsSnBr 3 heterojunction where the perovskite layer is grown by thin sequential deposition of SnBr 2 and CsBr allowing for immediate reaction. While other halides of CsSnX 3 (e.g. X=Cl, I) are extremely air sensitive and change color within seconds, illumination tests performed on unencapsulated CsSnBr 3 devices in ambient air show no change over the span of hours. Further, we evaluate the impact of low-temperature annealing and incorporation of various fluoride passivating dopant profiles via vapor deposition. Our results demonstrate an exciting alternative pathway to develop all-inorganic lead-free perovskite photovoltaics.
