Abstract
A process for annealing large-area multilayer bodies by supplying a quantity of energy at an annealing rate of at least 1° C./s. To suppress temperature inhomogeneities during the annealing, different partial quantities of the quantity of energy are supplied to the layers of the multilayer body with a local and temporal resolution. The multilayer body is annealed in a container which has a base and a cover made from glass-ceramic. The process is used to produce a thin-film solar module.
