Impact of dynamic co-evaporation schemes on the growth of methylammonium lead iodide absorbers for inverted solar cells.

ABSTRACT: A variety of different synthesis methods for the fabrication of solar cell absorbers based on the lead halide perovskite methylammonium lead iodide (MAPbI₃, MAPI) have been successfully developed in the past. In this work, we elaborate upon vacuum-based dual source co-evaporation as an industrially attractive processing technology. We present non-stationary processing schemes and concentrate on details of co-evaporation schemes where we intentionally delay the start/end points of one of the two evaporated components (MAI and PbI₂). Previously, it was found for solar cells based on a regular n-i-p structure, that the pre-evaporation of PbI[Formula: see text] is highly beneficial for absorber growth and solar cell performance. Here, we apply similar non-stationary proce
