Abstract: Solar cell modules and methods of fabrication are described. In an embodiment, a pair of tandem solar cells are a step surface or trench within the top subcell of a tandem solar cell is at least partially filled with another material such as an insulator support or electrically conductive support to transfer stress away from the absorber layer of the top subcell of the tandem solar cells when stacked or connected with ribbon.

Abstract: Hybrid solar cell plates with integrated bypass diodes and modules thereof are described. In an embodiment, a hybrid solar cell plate includes a step surface including a floor and a step edge extending from the floor and across a thickness of a top subcell. A bypass diode is over the floor and laterally adjacent to the step edge.

Abstract: Solar cell interconnect with bypass diodes are described. In an embodiment, a semiconductor-based bypass layer is formed over a top electrode layer of a solar cell and spans over a vertical interconnect providing vertical interconnection between the bottom electrode layer and top electrode layer of serial solar cells. A bypass electrode layer is formed over the semiconductor-based bypass layer and in contact with the top electrode layer for one of the solar cells.

Abstract: Vapor phase transport systems and methods of depositing perovskite films are described. In an embodiment, a deposition method includes feeding a perovskite solution or constituent powder to a vaporizer, followed by vaporization and depositing the constituent vapor as a perovskite film. In an embodiment, a deposition system and method includes vaporizing different perovskite precursors in different vaporization zones at different temperatures, followed by mixing the vaporized precursors to form a constituent vapor, and depositing the constituent vapor as a perovskite film.
