Development of chemical vapour deposition fabrication of perovskites for photovoltaics

摘要

A CVD process has been developed with focus on mixed caesium lead iodide/bromide (CsPbl_(3-1) Br_x) compositions to optimise the perovskite E_g versus stability in ambient laboratory conditions for device fabrication. An initial study to establish a CVD process for mixed cation perovskites is also reported.
