FLEXIBLE III-V SOLAR CELL STRUCTURE |
摘要 |
Solar cell structures include stacked layers in reverse order on a germanium substrate wherein a n++ (In)GaAs buffer layer plays dual roles as buffer and contact layers in the inverted structures. The absorbing layers employed in such exemplary structures are III-V layers such as (In)GaAs. Controlled spalling may be employed as part of the fabrication process for the solar cell structures, which may be single or multi-junction. The requirement for etching a buffer layer is eliminated, thereby facilitating the manufacturing process of devices using the disclosed structures. |
