Longstanding engineering challenges have been the focus of thin-film perovskite optoelectronic devices since their discovery as a contender for the 'next best' photovoltaic material. Dr. Hou's team have now demonstrated that utilizing vapor deposition techniques, the material has real-world potential, and have officially brought another step closer to widespread adoption.
“With vapour-deposited perovskites, we are addressing two fundamental challenges at one go: compatibility with real industrial silicon wafers and stable operation under heat,” said Asst Prof Hou. “This is the first evidence of vapour-grown perovskite tandem cells achieving the required durability for commercial deployment, bringing us closer to practical and reliable tandem solar modules.”
