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.

Bypass diode interconnect for thin film solar modules

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.

Vapor phase transport systems for depositing perovskite semiconductors

Thin-film solar cell modules and serial cell-to-cell interconnect structures and methods of fabrication are described. In an embodiment, solar cell module and interconnect includes a conformal transport layer over a subcell layer. The conformal transport layer may also laterally surround an outside perimeter the subcell layer.

Stable perovskite module interconnects

Thin-film solar cell modules and serial cell-to-cell interconnect structures and methods of fabrication are described. In an embodiment, a solar cell interconnect includes a bypass diode between adjacent solar cells to allow the flow of current around a single solar cell.

Integration of bypass diodes within thin film photovoltaic module interconnects

A perovskite-based solar cell comprising a transparent electrode disposed on a buffer layer that protects the perovskite from damage during the deposition of the electrode is disclosed. The buffer material is deposited using either low-temperature atomic-layer deposition, chemical-vapor deposition, or pulsed chemical-vapor deposition. In some embodiments, the perovskite material is operative as an absorption layer in a multi-cell solar-cell structure. In some embodiments, the perovskite material is operative as an absorption layer in a single junction solar cell structure.

Solar cell comprising a metal-oxide buffer layer and method of fabrication

A buffer layer for protecting an organic layer during high-energy deposition of an electrically conductive layer is disclosed. Buffer layers in accordance with the present invention are particularly well suited for use in perovskite-based single-junction solar cells and double-junction solar cell structures that include at least one perovskite-based absorbing layer. In some embodiments, the buffer layer comprises a layer of oxide-based nanoparticles that is formed using solution-state processing, in which a solution comprising the nanoparticles and a volatile solvent is spin coated onto a structure that includes the organic layer. The solvent is subsequently removed in a low-temperature process that does not degrade the organic layer.
