Techniques for performing improved machine learning using decision trees are disclosed. In one example, a system includes a plurality of decision tree structures, and configuration logic operatively coupled to the plurality of decision tree structures. The configuration logic selectively configures the plurality of decision tree structures to form at least one of: one or more combined decision tree structures, wherein a combined decision tree structure comprises multiple interconnected ones of the plurality of decision tree structures; and one or more individual decision tree structures, wherein an individual decision tree structure comprises a single one of the plurality of decision tree structures.

Embodiments relate to a method for annealing a solar cell structure including forming an absorber layer on a molybdenum (Mo) layer of a solar cell base structure. The solar cell base structure includes a substrate and the Mo layer is located on the substrate. The absorber layer includes a semiconductor chalcogenide material. Annealing the solar cell base structure is performed by exposing an outer layer of the solar cell base structure to a plasma.
