Organic and inorganic halide perovskites have demonstrated rapid progress of optoelectronic figures-of-merit, strongly supporting their application in electroluminescent devices, photovoltaics as well as X-ray and optical detectors. However, the lack of a mature fabrication technology is a major challenge for their commercialization. Chemical vapor deposition (CVD) is an appealing choice due to its flexibility/scalability, high purity and superior process control. In this work, we present a prototype perovskite hot-wall CVD reactor, including details of powder-based sublimation sources, reactor design as well as selected results from deposited perovskite compounds, first optoelectronic devices and remaining challenges.
