DURHAM, N.C., Jan. 5, 2018 — A thin-film deposition method for creating hybrid thin-film materials, applied to the fabrication of perovskite cells, could lead to a means to develop next-gen solar materials. Researchers at Duke University have developed an approach to manufacturing perovskites using pulsed laser evaporation. A solution containing the molecular building blocks for the perovskite is frozen, and the frozen block is blasted with a laser in a vacuum chamber. The laser vaporizes a tiny piece of the frozen target — about the size of a dimple on a golf ball — and the vapor travels upward in a...Read full articleRelated content from Photonics MediaARTICLESFabrication Method Could Expand Perovskite ProductionA simple, synthetic process for fabricating stable perovskite solar cells has overcome a preventative challenge to large-scale production, and, as a result, to product commercialization.
